                    TITLE 43--PUBLIC LANDS: INTERIOR
 
    CHAPTER II--BUREAU OF LAND MANAGEMENT, DEPARTMENT OF THE INTERIOR
 
PART 8340--OFF-ROAD VEHICLES--Table of Contents
 
                    Subpart 8343--Vehicle Operations
 
Sec. 8343.1  Standards.


    (a) No off-road vehicle may be operated on public lands unless 
equipped with brakes in good working condition.
    (b) No off-road vehicle equipped with a muffler cutout, bypass, or 
similar device, or producing excessive noise exceeding Environmental 
Protection Agency standards, when established, may be operated on public 
lands.
    (c) By posting appropriate signs or by marking a map which shall be 
available for public inspection at local Bureau offices, the authorized 
officer may indicate those public lands upon which no off-road vehicle 
may be operated unless equipped with a properly installed spark 
arrester. The spark arrester must meet either the U.S. Department of 
Agriculture--Forest Service Standard 5100-1a, or the 80-percent 
efficiency level standard when determined by the appropriate Society of 
Automotive Engineers (SAE) Recommended Practices J335 or J350. These 
standards include, among others, the requirements that: (1) The spark 
arrester shall have an efficiency to retain or destroy at least 80 
percent of carbon particles for all flow rates, and (2) the spark 
arrester has been warranted by its manufacturer as meeting this 
efficiency requirement for at least 1,000 hours subject to normal use, 
with maintenance and mounting in accordance with the manufacturer's 
recommendation. A spark arrester is not required when an off-road 
vehicle is being operated in an area which has 3 or more inches of snow 
on the ground.
    (d) Vehicles operating during night hours, from a half-hour after 
sunset to a half-hour before sunrise, shall comply with the following:
    (1) Headlights shall be of sufficient power to illuminate an object 
at 300 feet at night under normal, clear atmospheric conditions. Two- or 
three-wheeled vehicles or single-tracked vehicles will have a minimum of 
one headlight. Vehicles having four or more wheels or more than a single 
track will have a minimum of two headlights, except double tracked 
snowmachines with a maximum capacity of two people may have only one 
headlight.
    (2) Red taillights, capable of being seen at a distance of 500 feet 
from the rear at night under normal, clear atmospheric conditions, are 
required on vehicles in the same numbers as headlights.
