TITLE 23--HIGHWAYS
CHAPTER I--FEDERAL HIGHWAY ADMINISTRATION, DEPARTMENT OF TRANSPORTATION
PART 658--TRUCK SIZE AND WEIGHT, ROUTE DESIGNATIONS--LENGTH, WIDTH AND WEIGHT LIMITATIONS--Table of Contents
Sec. 658.23 LCV freeze; cargo-carrying unit freeze.
(a)(1) Except as otherwise provided in this section and except for
tow trucks with vehicles in tow, a State may allow the operation of
LCV's on the Interstate System only as listed in appendix C to this
part.
(2) Except as otherwise provided in this section, a State may not
allow the operation on the NN of any CMV combination with two or more
cargo-carrying units (not including the truck tractor) whose cargo-
carrying units exceed:
(i) The maximum combination trailer, semitrailer, or other type of
length limitation authorized by State law or regulation of that State on
or before June 1, 1991; or
(ii) The length of the cargo-carrying units of those CMV
combinations, by specific configuration, in actual, lawful operation on
a regular or periodic basis (including continuing seasonal operation) in
that State on or before June 1, 1991, as listed in appendix C to this
part.
(b) Notwithstanding paragraph (a)(2) of this section, the following
CMV combinations with two or more cargo-carrying units may operate on
the NN.
[[Page 264]]
(1) Truck tractor-semitrailer-trailer and truck tractor-semitrailer-
semitrailer combinations with a maximum length of the individual cargo
units of 28.5 feet or less.
(2) Vehicles described in Sec. 658.13(e) and (g).
(3) Truck-trailer and truck-semitrailer combinations with an overall
length of 65 feet or less.
(4) Maxi-cubes.
(5) Tow trucks with vehicles in tow.
(c) For specific safety purposes and road construction, a State may
make minor adjustments of a temporary and emergency nature to route
designations and vehicle operating restrictions applicable to
combinations subject to 23 U.S.C. 127(d) and 49 U.S.C. 31112 and in
effect on June 1, 1991 (July 6, 1991, for Alaska). Adjustments which
last 30 days or less may be made without notifying the FHWA. Minor
adjustments which exceed 30 days require approval of the FHWA. When such
adjustments are needed, a State must submit to the Division Office of
Motor Carriers, by the end of the 30th day, a written description of the
emergency, the date on which it began, and the date on which it is
expected to conclude. If the adjustment involves route designations, the
State shall describe the new route on which vehicles otherwise subject
to the freeze imposed by 23 U.S.C. 127(d) and 49 U.S.C. 31112 are
allowed to operate. To the extent possible, the geometric and pavement
design characteristics of the alternate route should be equivalent to
those of the highway section which is temporarily unavailable. Approval
or disapproval by Office of Motor Carriers officials of adjustments
involving route designations shall be coordinated with the Division
Administrator. If the adjustment involves vehicle operating
restrictions, the State shall list the restrictions that have been
removed or modified. Approval or disapproval of the adjustment by the
Division Office of Motor Carriers shall take place only after
consultation with the Regional Office of Motor Carriers. If the
adjustment is approved, a copy of the approved submission shall be
forwarded through the Regional Office of Motor Carriers, to the
Associate Administrator for Motor Carriers at Headquarters, who will
publish the notice of adjustment, with an expiration date, in the
Federal Register. Requests for extensions of time beyond the originally
established conclusion date shall be subject to the same approval and
publication process as the original request. If upon consultation with
the Regional Office of Motor Carriers, a decision is reached that minor
adjustments made by a State are not legitimately attributable to road or
bridge construction or safety, the Division Office of Motor Carriers
will so inform the State, and the original conditions of the freeze must
be reimposed immediately. Failure to do so may subject the State to a
penalty pursuant to 23 U.S.C. 141.
(d) A State may issue a permit authorizing a CMV to transport an
overlength nondivisible load on two or more cargo-carrying units on the
NN without regard to the restrictions in Sec. 658.23(a)(2).
(e) States further restricting or prohibiting the operation of
vehicles subject to 23 U.S.C. 127(d) and 49 U.S.C. 31112 after June 1,
1991, shall notify the FHWA Division Office of Motor Carriers within 30
days after the restriction is effective. The Division Office of Motor
Carriers shall forward the information through the Regional Office of
Motor Carriers to the Associate Administrator for Motor Carriers at
Headquarters. The FHWA will publish the restriction in the Federal
Register as an amendment to appendix C to this part. Failure to provide
such notification may subject the State to a penalty pursuant to 23
U.S.C. 141.
(f) The Federal Highway Administrator, on his or her own motion or
upon a request by any person (including a State), shall review the
information set forth in appendix C to this part. If the Administrator
determines there is cause to believe that a mistake was made in the
accuracy of the information contained in appendix C to this part, the
Administrator shall commence a proceeding to determine whether the
information published should be corrected. If the Administrator
determines that there is a mistake in the accuracy of the information
contained in appendix C to this part, the Administrator shall publish
[[Page 265]]
in the Federal Register the appropriate corrections to reflect that
determination.

Appendix C to Part 658--Trucks Over 80,000 Pounds on the Interstate
System and Trucks Over STAA Lengths on the National Network
This appendix contains the weight and size provisions that were in
effect on or before June 1, 1991 (July 6, 1991 for Alaska), for vehicles
covered by 23 U.S.C. 127(d) (LCV's) and 49 U.S.C. app. 2311(j)
(commercial motor vehicles (CMV's) with 2 or more cargo-carrying units).
Weights and dimensions are ``frozen'' at the values shown here, which
were in effect on June 1, 1991 (Alaska, July 6, 1991). All vehicles are
listed by configuration type.
Trucks Over 80,000 Pounds on the Interstate System
In the State-by-State descriptions, CMV combinations which can also
be LCV's are identified with the letters ``LCV'' following the type of
combination vehicle. The maximum allowable gross vehicle weight is given
in this appendix (in thousands of pounds indicated by a ``K''), as well
as information summarizing the operational conditions, routes, and legal
citations. The term ``Interstate System'' as used herein refers to the
Dwight D. Eisenhower System of Interstate and Defense Highways.
Trucks Over STAA Lengths on the National Network
Listed for each State by combination type is either:
1. The maximum cargo-carrying length (shown in feet); or
2. A notation that such vehicle is not allowed (indicated by a
``NO'').
CMV's are categorized as follows:
1. A CMV combination consisting of a truck tractor and two trailing
units.
2. A CMV combination consisting of a truck tractor and three
trailing units.
3. CMV combinations with two or more cargo-carrying units not
included in descriptions 1 or 2.
In the following table the left number is the maximum cargo-carrying
length measured in feet from the front of the first cargo unit to the
rear of the last cargo unit. This distance is not to include length
exclusive devices which have been approved by the Secretary or by any
State. Devices excluded from length determination shall only include
items whose function is related to the safe and efficient operation of
the semitrailer or trailer. No device excluded from length determination
shall be designed or used for carrying cargo. The right number is the
maximum gross weight in thousands of pounds that the type of vehicle can
carry when operating as an LCV on the Interstate System. For every State
where there is a length or weight number in the table that follows,
additional information is provided.

(1)--State submission includes multiple vehicles in this category--see
individual State listings.
(2)--No maximum weight is established as this vehicle combination is not
considered an ``LCV'' per the ISTEA definition. Florida's combination
is not allowed to operate on the Interstate System, and the
combinations for Hawaii, Mississippi, and Nebraska are not allowed to
exceed 80,000 pounds.
(3)--No maximum cargo-carrying length is established for this
combination. Because State law limits each trailing unit to not more
than 28.5 feet in length, this combination is allowed to operate on
all NN routes under the authority of the STAA of 1982, regardless of
actual cargo-carrying length. The maximum weight listed is New
Mexico's maximum allowable gross weight on the Interstate System under
the grandfather authority of 23 U.S.C. 127.
(4)--These dimensions do not apply to the same combinations. The 110-
foot length is limited to vehicles entering from Oklahoma, also
limited to 90K gross weight. The 120K gross weight is limited to
vehicles entering from Kansas, also limited to a cargo carrying length
of 109 feet.
The following abbreviation convention is used throughout the
narrative State-by-State descriptions for the captions OPERATIONAL
CONDITIONS, ROUTES, and LEGAL CITATIONS: two letter State abbreviation,
dash, ``TT'' for truck tractor, and 2 or 3 for two or three trailing
units. For example, the phrase ``Arizona truck tractor and 2 trailing
units'', would be noted as ``AZ-TT2''; the phrase ``Indiana truck
tractor and 3 trailing units'' would be noted as ``IN-TT3'', etc.
STATE: ALASKA
COMBINATION: Truck tractor and 2 trailing units
LENGTH OF THE CARGO-CARRYING UNITS: 95 feet

appropriate endorsement.
VEHICLE: Combinations with an overall length greater than 75 feet,
measured bumper to bumper, must display an ``OVERSIZE
warning sign on the front and rear. In combinations where one cargo-
carrying unit is more than 5,000 pounds heavier than the other, the
heavier unit shall be placed immediately behind the power unit. Weather
restrictions are imposed when hazardous conditions exist, as determined
by the Alaska Department of Transportation and Public Facilities
(DOT&PF) and the Alaska Department of Public Safety, Division of State
Troopers. Time of day travel is not restricted.
PERMIT: None required.
ACCESS: Alaska allows reasonable access not to exceed 5 miles to
reach or return from terminals and facilities for food, fuel, or rest.
The most direct route must be used. The Commissioner of the Alaska
DOT&PF may allow access to specific routes if it can be shown that
travel frequency, necessity, and route accommodation are required.

COMBINATION: Truck tractor and 3 trailing units--LCV
LENGTH OF THE CARGO-CARRYING UNITS: 109 feet
MAXIMUM ALLOWABLE GROSS WEIGHT: 120,000 pounds
OPERATIONAL CONDITIONS: The operations of triple trailing unit
combinations are governed by two sets of criteria: (1) The Turnpike and
Turnpike access rules, and (2) the SVC rules which apply off of the
Turnpike except in the case of vehicles operating under Turnpike access
authority. The Turnpike and Turnpike access rules allow a maximum
combination vehicle length of 119 feet overall. The SVC rules require
``Triples'' to have trailers of no more than 28.5 feet maximum length or
a cargo-carrying length of approximately 95 feet.
The Turnpike and Turnpike access rules have no time-of-day travel
restrictions or other special requirements.
The SVC rules have several operational conditions. SVC's cannot
operate on holidays or during holiday weekends. SVC's cannot be
dispatched or operated during adverse weather conditions. SVC's must
travel in the right lane, except for passing, and the following distance
is 100 feet for every 10 miles per hour. SVC permits can include any
restrictions deemed necessary, including specific routes and hours,
days, and/or seasons of operation. Rules and regulations can be
promulgated regarding driver qualifications, vehicle equipment, and
operational standards.
WEIGHT: All triple trailing unit combinations must comply with the
Federal Bridge Formula with maximum axle weights of 20,000 pounds on a
single axle and 34,000 pounds on a tandem axle. The maximum gross weight
is 120,000 pounds on the Turnpike and Turnpike access routes, but the
SVC's have a maximum weight of 110,000 pounds.
DRIVER: A commercial driver's license with the appropriate
endorsement is required under both Turnpike and SVC rules. In addition,
for SVC operation drivers must have completed SVC driver training and a
company road test. Drivers must also have 2 years of experience driving
tractor-semitrailers and 1 year driving doubles.
VEHICLE: Vehicle requirements apply to the SVC program only. All
axles, except steering axles, must have dual wheels, and all vehicles
must be able to achieve and maintain a speed of 40 miles per hour on all
grades. Antispray mud flaps shall be attached to the rear of each axle
except the steering axle. Mud flaps shall have a surface designed to
absorb and deflect excess moisture to the road surface. Drop and lift
axles are prohibited. Vehicles may have a minimum of six and a maximum
of nine axles. The heaviest trailers are to be placed forward. Hazardous
cargo is prohibited. Convex mirrors are required on both sides of the
cab. Equipment must comply with the requirements of 49 CFR 390-399.
Any SVC shall be stable at all times during normal braking and
normal operation. When traveling on a level, smooth paved surface, an
SVC shall follow the towing vehicle without shifting or swerving beyond
the restraints of the lane of travel.
PERMIT: Same as the KS-TT2 combination on the Turnpike and Turnpike
access routes. A fee per company plus a permit fee for each power unit
is required for the SVC program, and the SVC permits are valid for 1
year. SVC's operated pursuant to regulation 36-1-33 under an annual
permit shall be covered by insurance.
ACCESS: Turnpike access routes include all routes between the
Turnpike and a motor freight terminal located within a 10-mile radius of
each toll booth, except at the northeastern end of the Turnpike where a

OPERATIONAL CONDITIONS:
WEIGHT: Any combination of vehicles may not exceed a maximum gross
weight of 127,400 pounds. The maximum gross weight of the tractor and
first semitrailer shall not exceed 71,000 pounds. The maximum gross
weight of each unit of dolly and semitrailer
[[Page 290]]
shall not exceed 56,400 pounds. The maximum gross weight for the tractor
and first semitrailer is governed by the formula 35,000 pounds plus
1,000 pounds per foot between the center of the foremost axle and the
center of the rearmost axle of the semitrailer. The maximum gross weight
on any one axle is 22,400 pounds, and on any tandem axle it is 36,000
pounds. Axles less than 46 inches between centers are considered to be
one axle.
DRIVER: The driver must have a commercial driver's license with the
appropriate endorsement and must be registered with the Massachusetts
Turnpike Authority (MTA). Registration shall include all specified
driving records, safety records, physical examinations, and minimum of 5
years of driving experience with tractor trailers.
VEHICLE:
(1) Brake Regulation. The brakes on any vehicle, dolly converter, or
combination of vehicles used in tandem-trailer operations as a minimum
shall comply with Federal Motor Carrier Safety Regulations in 49 CFR
part 393. In addition, any vehicle, dolly converter or combination of
vehicles used in tandem-trailer operations shall meet the requirements
of the provisions of the Massachusetts Motor Vehicle Law. Tandem-trailer
combinations certified on or after June 1, 1968, shall be equipped with
suitable devices to accelerate application and release of the brakes of
the towed vehicle.
(2) Axles. A tractor used to haul a tandem trailer combination with
a gross weight of more than 110,000 pounds shall be equipped with tandem
rear axles, each of which shall be engaged to bear its full share of the
load on the roadway surface.
(3) Tandem Assembly. When the gross weight of the trailers vary by
more than 20 percent, they shall be coupled with the heaviest trailer
attached to the tractor. Coupling devices and towing devices shall
comply with the Federal regulations as stated in 49 CFR part 393. When
the distance between the rear of the one semitrailer and the front of
the following semitrailer is 10 feet or more, the dolly shall be
equipped with a device, or the trailers shall be connected along the
sides with suitable material, which will indicate to other Turnpike
users that the trailers are connected and are in effect one unit. The
MTA shall approve the devices or connections to be used on the
semitrailers that would indicate it is one unit. Coupling devices shall
be so designed, constructed, and installed, and the vehicles in a tandem
trailer combination shall be so designed and constructed to ensure that
when traveling on a level, smooth paved surface they will follow in the
path of the towing vehicle without shifting or swerving over 3 inches to
each side of the path of the towing vehicle when it is moving in a
straight line. A tandem trailer unit may pass another vehicle traveling
in the same direction only if the speed differential will allow the
tandem trailer unit to complete the maneuver and return to the normal
driving lane within a distance of 1 mile.
Each truck tractor shall be equipped with at least one spare fuse or
other overload protective device, if the devices are not of a reset
type, for each kind and size used. The vehicle is to carry at least one
set of tire chains for at least one driving wheel on each side between
October 15 and May 1 of each year. Each truck tractor shall carry a fire
extinguisher which shall have an aggregate rating of 20 BC.
PERMIT: A permittee must demonstrate to the MTA that it has
insurance coverage of the type and amounts required by Turnpike
regulation. Both the tractor manufacturer and the permittee shall
certify to the MTA, prior to the approval of a tractor, that it is
capable of hauling the maximum permissible gross load to be transported
by the permittee at a speed not less than 20 miles per hour on all
portions of the turnpike system. The MTA may revoke or temporarily
suspend any permit at will and the instructions of the MTA or
Massachusetts State Police shall be complied with immediately.
ACCESS: Makeup and breakup areas. Tandem trailer units shall not
leave the Turnpike right-of-way and shall be assembled and disassembled
only in designated areas.

LENGTH OF THE CARGO-CARRYING UNITS: 102 feet
MAXIMUM ALLOWABLE GROSS WEIGHT: 143,000 pounds
OPERATIONAL CONDITIONS:
WEIGHT: The following information pertains to tandem trailer
combinations with either trailer more than 28.5 feet long but not more
than 48 feet long. A nine-axle combination vehicle may not exceed a
total maximum gross weight of 143,000 pounds. An eight-axle combination
vehicle may not exceed a total maximum gross weight of 138,400 pounds.
The maximum gross weight that may be carried upon any combination of
units is limited by the maximum gross weight that can be carried upon
the axles as follows. For a nine-axle combination: Drive axles--36,000
pounds, axles four/five--36,000 pounds, axles six/seven--27,000 pounds,
and axles eight/nine--36,000 pounds. A minimum 12-foot axle spacing
between the fifth and sixth axles is also required on the nine-axle LCV.
For an eight-axle combination: Drive axles--36,000 pounds, axles four/
five--36,000 pounds, sixth axle--22,400 pounds, and axles seven/eight--
36,000 pounds. The eight-axle LCV has no minimum axle-spacing
requirements. For gross weights in excess of 138,400 pounds the
combination must include a tandem-axle dolly to meet the nine-axle
requirements. Maximum permissible gross weight for B-train combination
is 127,000 pounds.
When the gross weight of the two trailers in a tandem combination
vary more than 20 percent, the heaviest of the two must be placed in the
lead position.
For tandem trailer combinations in which neither trailing unit
exceeds 28.5 feet in length the following maximum allowable weights
apply: for a single axle--28,000
[[Page 298]]
pounds (except that steering axles may not exceed 22,400 pounds), for a
tandem axle--42,500 pounds, for a tri-axle--52,500 pounds. The gross
weight may not exceed 100,000 pounds or the manufacturers gross weight
rating, whichever is lower.
DRIVER: For operation on highways under the jurisdiction of the New
York State Thruway Authority (NYSTA), except for the full length of I-84
and that portion of I-287 from Thruway exit 8 to I-95, the driver must
have a commercial driver's license with the appropriate endorsement, and
hold a Tandem Trailer Driver's Permit issued by the NYSTA. In order to
obtain an NYSTA driver's permit, an applicant must (1) hold a valid
commercial driver's license with multiple-trailer endorsement; (2) be
over 26 years old, in good health, and have at least 5 years of provable
experience driving tractor-trailer combinations; and (3) meet all other
application requirements with regard to driving history established by
the NYSTA. Qualified drivers receive a Tandem Trailer Driver's Permit
for Tandem Vehicle Operation which is valid only for the operation of
the certified equipment owned by the company to which the permit is
issued.
For operation on highways under the jurisdiction of the New York
State DOT, cities not wholly included in one county, the full length of
I-84 and that portion of I-287 from Thruway exit 8 to I-95, the driver
must have a commercial driver's license with the appropriate
endorsement.
VEHICLE: All vehicles must meet the requirements of applicable
Federal and State statutes, rules, and regulations. Vehicles operating
on highways under the jurisdiction of the NYSTA, except for the full
length of I-84 and that portion of I-287 from Thruway exit 8 to I-95,
must also meet the following additional requirements. The tractor
manufacturer and the permittee shall certify to the NYSTA prior to the
approval of the tractor that it is capable of hauling the maximum
permissible gross load at a speed of not less than 20 miles per hour on
all portions of the thruway system.
The brakes on any vehicle, dolly converter, or combination of
vehicles shall comply with 49 CFR part 393 and, in addition, any vehicle
or dolly converter shall meet the provisions of the New York State
Traffic Law.
Tandem trailer operations shall be equipped, at a minimum, with
emergency equipment as required by 49 CFR part 393, subpart H, as
amended, tire chains from October 15 to May 1 of each year, a fire
extinguisher with an aggregate rating of 20BC, and each trailer with
specific lamps and reflectors.
All tractors certified by the NYSTA for use with tandem trailers
will be assigned an identification number by the NYSTA which must be
placed on the vehicle. The number must be at least 3 inches in height
and visible to a person standing at ground level opposite the driver's
position in the cab.
Axle Type. Tractors to be used for hauling 110,000 pounds or more
shall be equipped with tandem rear axles, both with driving power.
Tractors to be used for hauling 110,000 pounds or less may have a single
drive axle. Tandem combinations using single wheel tires commonly
referred to as ``Super Singles'' are required to use triple-axle
tractors, dual-axle trailers, and dual-axle dollies.
Dollies. Every converter dolly certified on and after June 1, 1968,
used to convert a semitrailer to a full trailer may have either single
or tandem axles at the option of the permittee. Single-axle dollies may
not utilize low profile tires. Combination vehicles with a gross weight
in excess of 138,400 pounds must have a tandem-axle dolly to meet the
nine-axle requirement. If the distance between two semitrailers is 10
feet or more, the dolly shall be equipped with a device or the trailers
connected along the sides with suitable material to indicate they are in
effect one unit. The devices or connection shall be approved by the
NYSTA prior to use on a tandem trailer combination. The NYSTA tandem-
trailer provisions require that converter dollies shall be coupled with
one or more safety chains or cables to the frame or an extension of the
frame of the motor vehicle by which it is towed. Each dolly converter
must also be equipped with mud flaps. Tandem combinations using a
sliding fifth wheel attached to the lead trailer, known as a ``B-Train''
combination, will require a separate Thruway Engineer Service approval
prior to the initial tandem run. Special provisions regarding B-Trains
will be reviewed at the time of the application or request for use on
the Thruway.
PERMIT: For operation on highways under the jurisdiction of the New
York State DOT, cities not wholly included in one county, or the
following highway sections under NYSTA jurisdiction; the full length of
I-84 and that portion of I-287 from Thruway exit 8 to I-95, a permit to
exceed the weight limits set forth in section 385(15) of the New York
State Vehicle and Traffic Law must be obtained from the State DOT, city
involved, or the NYSTA. A fee is charged for the permit.
For operation on highways under the jurisdiction of the NYSTA,
except for the full length of I-84 and that portion of I-287 from
Thruway exit 8 to I-95, companies must file an application for a Tandem
Trailer Permit with the NYSTA. Permits are issued to such companies upon
meeting qualifications, including insurance, for tandem combinations
over 65 feet in length. No permit fee is charged; however, Thruway tolls
are charged for each use of the Thruway, and the equipment must be
certified by the NYSTA annually. The annual re-certification of
equipment is handled by: New York State

are not allowed on any portion of the Interstate System under the
jurisdiction of the Ohio DOT.
WEIGHT: The OTC has established the following provisions for
operation:
Maximum Weight: Single axle = 21,000 pounds; tandem axle spaced 4
feet or less apart = 24,000 pounds; tandem axle spaced more than 4 feet
but less than 8 feet apart = 34,000 pounds; gross weight for doubles 90
feet or less in length = 90,000 pounds; gross weight for doubles over 90
feet but less than 112 feet in length = 127,400 pounds.
DRIVER: The driver must have a commercial driver's license with the
appropriate endorsement, be over 26 years of age, in good health, and
shall have not less than 5 years of experience driving tractor-trailer
or tractor-short double trailer motor vehicles. Such driving experience
shall include experience throughout the four seasons. Drivers must
comply with the applicable current requirements of the Federal Motor
Carrier Safety Regulations, Federal Hazardous Materials Regulations, and
the Economic and Safety regulations of the Ohio Public Utility
Commission.
VEHICLE: Vehicles being operated under permit at night must be
equipped with all lights and reflectors required by the Ohio Public
Utilities Commission and the Federal Motor Carrier Safety Regulations,
except that the trailer shall be equipped with two red tail lights and
two red or amber stop lights mounted with one set on each side. Trailer
and semitrailer length for doubles cannot exceed 48 feet, and mixed
trailer length combinations are not allowed for combination vehicles
over 90 feet in length. Combined cargo-carrying length, including the
trailer hitch, cannot be less than 80 feet or more than 102 feet. The
number of axles on a double shall be a minimum of five and a maximum of
nine. A tractor used in the operation of a double shall be capable of
hauling the maximum weight at a speed of not less than 40 miles per hour
on all portions of the Turnpike.
PERMIT: A special permit is required if the vehicle is over 102
inches wide, 14 feet high, or 65 feet in length including overhang.
Tractor-semitrailer-semitrailer combinations require a permit if over 75
feet in length, excluding an allowed 3-foot front overhang and a 4-foot
rear overhang. For vehicles over 120 inches wide, 14 feet high, or 80
feet long or if any unit of the combination vehicle is over 60 feet in
length, travel is restricted to daylight hours Monday through noon
Saturday, except holidays and the day before and after holidays.
Operators are restricted to daylight driving if the load overhang is
more than 4 feet. A ``Long Double Trailer Permit'' issued by the OTC is
required for operation of doubles in excess of 90 feet in length. Towing
units and coupling devices shall have sufficient structural strength to
ensure safe operation. Vehicles and coupling devices shall be so
designed, constructed, and installed in a double as to ensure that any
towed vehicles when traveling on a level, smooth paved surface will
follow in the path of the towing vehicle without shifting or swerving
more than 3 inches to either side of the path of the towing vehicle when
the latter is moving in a straight line. Vehicle coupling devices and
brakes shall meet the requirements of the Ohio Public Utilities
Commission and Federal Motor Carrier Safety Regulations. The distance
between the rearmost axle of a semitrailer and the front axle of the
next semitrailer in a coupled double unit shall not exceed 12 feet 6
inches. In no event shall the distance between the semitrailers coupled
in a double exceed 9 feet. Double and triple trailer combinations must
be equipped with adequate, properly maintained spray-suppressant mud
flaps on all axles except the steering axle. In the event that the gross
weights of the trailers vary by more than 20 percent, they shall be
coupled according to their gross weights with the heavier trailer
forward. A minimum distance of 500 feet shall be maintained between
double units and/or triple units except when overtaking and passing
another vehicle. A double shall remain in the right-hand, outside lane
except when passing or when emergency or work-zone conditions exist.
When, in the opinion of the OTC, the weather conditions are such that
operation of a double is inadvisable, the OTC will notify the permittee
that travel is prohibited for a certain period of time.
Class A and B explosives; Class A poisons; and Class 1, 2, and 3
radioactive material cannot be transported in double trailer
combinations. Other hazardous materials may be transported in one
trailer of a double. The hazardous materials should be placed in the
front trailer unless doing so will result in the second trailer weighing
more than the first trailer.
ACCESS: Tandem trailer units shall not leave the Turnpike right-of-
way and shall be

next larger number.
DRIVER: The driver must have a commercial driver's license with the
appropriate endorsement.
VEHICLE: For a combination which includes a truck tractor and two
trailing units, the lead trailing unit (semitrailer) may be up to 40
feet long. The second trailing unit may be up to 35 feet long. However,
the primary control is the total cargo-carrying distance which has a
maximum length of 68 feet. Any towed vehicles in a combination must be
equipped with safety chains or cables to prevent the towbar from
dropping to the ground in the event the coupling fails. The chains or
cables must have sufficient strength to control the towed vehicle in the
event the coupling device fails and must be attached with no more slack
than necessary to permit proper turning. However, this requirement does
not apply to a fifth-wheel coupling if the upper and lower halves of the
fifth wheel must be manually released before they can be separated.
PERMIT: A permit is required for operation if the gross combination
weight exceeds 80,000 pounds. A fee is charged. Permitted movements must
have the lighter trailing unit placed to the rear, and use splash and
spray devices when operating in rainy weather. Movement is not allowed
when road surfaces are hazardous due to ice or snow, or when other
atmospheric conditions make travel unsafe.

COMBINATION: Truck tractor and 2 trailing units--LCV
LENGTH OF CARGO-CARRYING UNITS: 100 feet
MAXIMUM ALLOWABLE GROSS WEIGHT: 129,000 pounds
OPERATIONAL CONDITIONS:
WEIGHT: For all combinations, the maximum gross weight on two or
more consecutive axles is limited by the Federal Bridge Formula but
cannot exceed 129,000 pounds. The weight on single axles or tandem axles
spaced 40 inches or less apart may not exceed 20,000 pounds. Tandem
axles spaced more than 40 inches but 96 inches or less may not exceed
34,000 pounds. Two consecutive sets of tandem axles may carry a gross
load of 34,000 pounds each, provided the overall distance between the
first and last axles of the tandems is 36 feet or more. The weight on
the steering axle may not exceed 600 pounds per inch of tire width.
For combinations with a cargo-carrying length greater than 81.5 feet
the following additional regulations also apply. The weight on all axles
(other than the steering axle) may not exceed 500 pounds per inch of
tire width. Lift axles and belly axles are not considered load-carrying
axles and will not count when determining allowable vehicle weight.
DRIVER: The driver must have a commercial driver's license with the
appropriate endorsement.
VEHICLE: For all combinations, a semitrailer or trailer may neither
be longer than nor weigh 3,000 pounds more than the trailer located
immediately in front of it. Towbars longer than 19 feet must be flagged
during daylight hours and lighted at night.
For combinations with a cargo-carrying length of 81.5 feet or less,
neither trailer may exceed 45 feet, including load overhang. Vehicles
may be 12 feet wide when hauling baled feed during daylight hours.
For combinations with a cargo-carrying length over 81.5 feet long,
neither trailer may exceed 48 feet, including load overhang. Loading the
rear of the trailer heavier than the front is not allowed. All axles
except the steering axle require dual tires. Axles spaced 8 feet or less
apart must weigh within 500 pounds of each other. The trailer hitch
offset may not exceed 6 feet. The maximum effective rear trailer
overhang may not exceed 35 percent of the trailer's wheelbase. The power
unit must have sufficient power to maintain 40 miles per hour. A ``LONG
LOAD'' sign measuring 18 inches high by 7 feet long with black on yellow
lettering 10 inches high is required on the rear. Offtracking is limited
to 8.75 feet for a turning radius of 161 feet.
Offtracking Formula = 161 - [161\2\ - (L1\2\ +
L2\2\ + L3\2\ + L4\2\ +
L5\2\ + L6\2\ + L7\2\ +
L8\2\)]\1/2\
Note: L1 through L8 are measurements between
points of articulation or vehicle pivot points. Squared dimensions to
stinger steer points of articulation are negative. For two trailing unit
combinations where at least one trailer is 45 feet long or longer, all
the dimensions used to calculate offtracking must be written in the
``Permit Restriction'' area of the permit along with the offtracking
value derived from the calculation.
PERMIT: For combinations with a cargo-carrying length of 81.5 feet
or less, a single-trip permit is required for movement on the Interstate
System if the gross vehicle weight exceeds 80,000 pounds. An annual or
single-trip permit is required for hauling baled feed over 102 inches
wide.
For combinations with a cargo-carrying length greater than 81.5
feet, a single-trip permit is required for all movements. Operations
must be discontinued when roads are slippery due to moisture, visibility
must be good, and wind conditions must not cause trailer whip or sway.
For all combinations, a fee is charged for any permit.
ACCESS: For combinations with a cargo-carrying length of 81.5 feet
or less, access is Statewide off the NN unless restricted by the South
Dakota DOT.

WEIGHT: Weight limits are as follows:
Single axle: 20,000 pounds
Tandem axle: 34,000 pounds
Gross weight: 129,000 pounds
Vehicles must comply with the Federal Bridge Formula
Tire loading on vehicles requiring an overweight or oversize permit
shall not exceed 500 pounds per inch of tire width for tires 11 inches
wide and greater, and 450 pounds per inch of tire width for tires less
than 11 inches
[[Page 309]]
wide as designated by the tire manufacturer on the side wall of the
tire. Tire loading on vehicles not requiring an overweight or oversize
permit shall not exceed 600 pounds per inch of tire width as designated
by the tire manufacturer on the sidewall.
DRIVER: The driver must have a commercial driver's license with the
appropriate endorsement. Carriers must certify that their drivers have a
safe driving record and have passed a road test administered by a
qualified safety supervisor.
VEHICLE: While in transit, no trailer shall be positioned ahead of
another trailer which carries an appreciably heavier load. An empty
trailer shall not precede a loaded trailer. Vehicles shall be powered to
operate on level terrain at speeds compatible with other traffic. They
must be able to maintain a minimum speed of 20 miles per hour under
normal operating conditions on any grade of 5 percent or less over which
the combination is operated and be able to resume a speed of 20 miles
per hour after stopping on any such grade, except in extreme weather
conditions.
Oversize signs are required on vehicles in excess of 75 feet in
length on two-lane highways.
A heavy-duty fifth wheel is required. All fifth wheels must be clean
and lubricated with a light-duty grease prior to each trip. The fifth
wheel must be located in a position which provides adequate stability.
Pick-up plates must be of equal strength to the fifth wheel. The kingpin
must be of a solid type and permanently fastened. Screw-out or folding-
type kingpins are prohibited.
All hitch connections must be of a no-slack type, preferably a
power-actuated ram. Air-actuated hitches which are isolated from the
primary air transmission system are recommended.
The drawbar length should be the practical minimum consistent with
the clearances required between trailers for turning and backing
maneuvers.
Axles must be those designed for the width of the body.
All braking systems must comply with State and Federal requirements.
In addition, fast air transmission and release valves must be provided
on all semitrailer and converter-dolly axles. A brake force limiting
valve, sometimes called a ``slippery road'' valve, may be provided on
the steering axle. Anti-sail type mud flaps are recommended.
The use of single tires on any combination vehicle requiring an
overweight or oversize permit shall not be allowed on single axles. A
single axle is defined as one having more than 8 feet between it and the
nearest axle or group of axles on the vehicle.
When traveling on a level, smooth paved surface, the trailing units
must follow in the path of the towing vehicle without shifting or
swerving more than 3 inches to either side when the towing vehicle is
moving in a straight line. Each combination shall maintain a minimum
distance of 500 feet from another commercial vehicle traveling in the
same direction on the same highway. Loads shall be securely fastened to
the transporter with material and devices of sufficient strength to
prevent the load from becoming loose, detached, dangerously displaced,
or in any manner a hazard to other highway users. The components of the
load shall be reinforced or bound securely in advance of travel to
prevent debris from being blown off the unit and endangering the safety
of the traveling public. Any debris from the special permit vehicle
deposited on the highway shall be removed by the permittee.
Bodily injury and property damage insurance is required before a
special Transportation Permit will be issued.
In the event any claim arises against the State of Utah, Utah
Department of Transportation, Utah Highway Patrol, or their employees
from the operation granted under the permit, the permittee shall agree
to indemnify and hold harmless each of them from such claim.
PERMIT: Permits must be purchased. The Utah DOT Motor Carrier Safety
Division will, on submission of an LCV permit request, assign an
investigator to perform an audit on the carrier, which must have an
established safety program that is in compliance with the Federal Motor
Carrier Safety Regulations (49 CFR parts 387-399), the Federal Hazardous
Materials Regulations (49 CFR parts 171-178), and a ``Satisfactory''
safety rating. The request must show a travel plan for the operation of
the vehicles. Permits are subject to Highway Patrol supervision and
permitted vehicles may be subject to temporary delays or removed from
the highways when necessary during hazardous road, weather, or traffic
conditions. The permit will be cancelled without refund if violated.
Expiration dates cannot be extended except for reasons beyond the
control of the permittee, including adverse weather. Permits are void if
defaced, modified, or obliterated. Lost or destroyed permits cannot be
duplicated and are not transferable.
ACCESS: Routes approved by the Utah DOT plus local delivery
destination travel on two-lane roads.
ROUTES: For combinations with a cargo-carrying length of 85 feet or
less, all NN routes. Combinations with a cargo-carrying length over 85

Appendix D to Part 658--Devices That Are Excluded From Measurement of
the Length or Width of a Commercial Motor Vehicle
The following devices are excluded from measurement of the length or
width of a commercial motor vehicle, as long as they do not carry
property and do not exceed the dimensional limitations included in
Sec. 658.16. This list is not exhaustive.
1. All devices at the front of a semitrailer or trailer including,
but not limited to, the following:
(a) A device at the front of a trailer chassis to secure containers
and prevent movement in transit;
(b) A front coupler device on a semitrailer or trailer used in road
and rail intermodal operations;
(c) Aerodynamic devices, air deflector;
(d) Air compressor;
(e) Certificate holder (manifest box);
(f) Door vent hardware;
(g) Electrical connector;
(h) Gladhand;
(i) Handhold;
(j) Hazardous materials placards and holders;
(k) Heater;
(l) Ladder;
(m) Non-load carrying tie-down devices on automobile transporters;
(n) Pickup plate lip;
(o) Pump offline on tank trailer;
(p) Refrigeration unit;
[[Page 313]]
(q) Removable bulkhead;
(r) Removable stakes;
(s) Stabilizing jack (anti-nosedive device);
(t) Stake pockets;
(u) Step;
(v) Tarp basket;
(w) Tire carrier; and
(x) Uppercoupler.
2. Devices excluded from length measurement at the rear of a
semitrailer or trailer including, but not limited to, the following:
(a) Handhold;
(b) Hazardous materials placards and holders;
(c) Ladder;
(d) Pintle hook;
(e) Removable stakes;
(f) Splash and spray suppression device;
(g) Stake pockets; and
(h) Step.
3. Devices excluded from width determination, not to exceed 3 inches
from the side of the vehicle including, but not limited to, the
following:
(a) Corner caps;
(b) Hazardous materials placards and holders;
(c) Lift pads for trailer on flatcar (piggyback) operation;
(d) Rain gutters;
(e) Rear and side door hinges and their protective hardware;
(f) Side marker lamps;
(g) Structural reinforcement for side doors or intermodal operation
(limited to 1 inch from the side within the 3 inch maximum extension);
(h) Tarping systems for open-top trailers;
(i) Movable devices to enclose the cargo area of flatbed
semitrailers or trailers, usually called tarping systems, where no
component part of the system extends more than 3 inches from the sides
or back of the vehicle when the vehicle is in operation. This exclusion
applies to all component parts of tarping systems, including the
transverse structure at the front of the vehicle to which the sliding
walls and roof of the tarp mechanism are attached, provided the
structure is not also intended or designed to comply with 49 CFR
393.106, which requires a headerboard strong enough to prevent cargo
from penetrating or crushing the cab; the transverse structure may be up
to 108 inches wide if properly centered so that neither side extends
more than 3 inches beyond the structural edge of the vehicle. Also
excluded from measurement are side rails running the length of the
vehicle and rear doors, provided the only function of the latter, like
that of the transverse structure at the front of the vehicle, is to seal
the cargo area and anchor the sliding walls and roof. On the other hand,
a headerboard designed to comply with 49 CFR 393.106 is load bearing and
thus limited to 102 inches in width. However, the ``wings'' designed to
close the gap between such a headerboard and the movable walls and roof
of a tarping system are width exclusive, provided they are add-on pieces
designed to bear only the load of the tarping system itself and are not
integral parts of the load-bearing headerboard structure;
(j) Tie-down assembly on platform trailers;
(k) Wall variation from true flat; and
(l) Weevil pins and sockets on low-bed trailers.
