Title 40, Chapter 8, Section 30
( 40-8-30)
Except as hereinafter provided in this part, the headlights or the
auxiliary driving light or the auxiliary passing light or
combination thereof on motor vehicles other than motorcycles or
motor driven cycles shall be so arranged that the driver may select
at will between distributions of light projected to different
elevations, and such lights may, in addition, be so arranged that
such selection can be made automatically, subject to the following
limitations: (1) There shall be an uppermost distribution of light, or
composite beam, so aimed and of such intensity as to reveal
persons and vehicles at a distance of at least 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 100 feet ahead; and 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 new motor vehicle other than a motorcycle or a motor
driven cycle registered in this state 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 headlights is in use and shall not otherwise be lighted. Such
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. |
