Idaho State Statutes - Idaho Attorney Directory

Except as otherwise
provided in this chapter, the head lamps or the auxiliary driving lamp or the
auxiliary passing lamp or their combinations on motor vehicles other than a
motorcycle or motor-driven cycle shall be so arranged that selection may be
made between distributions of light projected to different elevations, and the
lamps may be so arranged that the selection can be made automatically, subject
to the following requirements and limitations:
(1) There shall be an uppermost distribution of light, or composite beam,
so aimed and of an intensity to reveal persons and vehicles at a distance of
at least three hundred fifty (350) feet ahead for all conditions of loading.
(2) There shall be a lowermost distribution of light, or composite beam
so aimed and of sufficient intensity to reveal persons and vehicles at a
distance of at least one hundred (100) feet ahead. On a straight level road
under any condition of loading none of the high-intensity portion of the beam
shall be directed to strike the eyes of an approaching driver.
(3) Every motor vehicle manufactured after December 31, 1954, other than
a motorcycle or motor-driven cycle, which has multiple-beam road-lighting
equipment shall be equipped with a beam indicator, which shall be lighted
whenever the uppermost distribution of light from the head lamps is in use,
and shall not otherwise be lighted. The indicator shall be so designed and
located that when lighted it will be readily visible without glare to the
driver of the vehicle so equipped.
