 CHAPTER I--FEDERAL HIGHWAY ADMINISTRATION, DEPARTMENT OF TRANSPORTATION
 
PART 658_TRUCK SIZE AND WEIGHT, ROUTE DESIGNATIONS_LENGTH, WIDTH AND 
 
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.
    (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 
designation 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). Minor 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 FHWA, 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 alternate 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. If the adjustment 
involves vehicle operating restrictions, the State shall list the 
restrictions that have been removed or modified. If the adjustment is 
approved, the FHWA will publish the notice of adjustment, with an 
expiration date, in the Federal Register. Requests for extension of time 
beyond the originally established conclusion date shall be subject to 
the same approval and publications process as the original request. If 
upon consultation with the FHWA a decision is reached that minor 
adjustments made by a State are not legitimately attributable to road or 
bridge construction or safety, the FHWA will 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 within 30 days after the restriction is 
effective. 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 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

[[Page 304]]

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
