Sec. 18-108. Requirements of signal devices.[246]
(a) Every device intended and used to give a signal of
intention to turn or to stop a vehicle shall be so constructed
and so installed as to give a signal plainly visible in clear
weather and under normal traffic conditions from a distance
of at least one hundred feet to the rear and one hundred
feet to the front of the vehicle; except, that a stop signal
need be visible only to the rear; provided, that no front signal
shall be required on vehicles manufactured or assembled before
January 1, 1943.
(b) Motor vehicles, trailers and semitrailers, when temporarily
stopped on the traveled or paved portion of a street so
as to create a traffic hazard, shall use all four turn signals
simultaneously to signal approaching motorists of the existing
hazard whenever such vehicle is equipped with a device
which will cause the four turn signals to flash simultaneously.
All four signals may be flashed simultaneously on a vehicle
stopped at the scene of a traffic hazard, but in no event shall
all four signals be flashed simultaneously while the vehicle
is in motion. (Code 1959, § 18-108.)
