762 ARTICLE 56.

Slow-moving vehicles, including motor trucks, shall at all times keep as
close to the right-hand side of the highway as practicable, regard being
had to the width and construction of such highway.

All vehicles about to turn from the road upon which they are traveling
into any intersecting road shall gradually reduce their speed to a point not
exceeding twelve miles an hour for a distance of not less than twenty-five
feet before beginning to make such turn, and where the view of the inter-
secting road is obstructed, preserve such reduced rates of speed until the
turn has been completed.

Except as hereinafter provided, all vehicles shall have the right of way
over other vehicles approaching at intersecting public roads from the left,
and shall give right of way to those approaching from the right. The
operator of a vehicle entering a paved public highway, which is hereby
defined to be a highway having a hard, smooth surface, composed of
gravel, shells, crushed stone, paving blocks, asphalt, concrete or other simi-
lar substance, from an unpaved public highway, or from a private road
or drive, shall come to a full stop upon reaching the intersection, and
yield the right of way to all vehicles approaching on such paved public
highway. The operator of a vehicle upon a highway shall yield the right of
way to ambulances and police and fire department vehicles when the latter
are operated upon official business and the drivers thereof sound audible
signal by bell, siren or exhaust whistle. This provision shall not operate
to relieve the operator of an ambulance or of a police or fire department
vehicle from the duty to drive with due regard for the safety of all persons
using the highway nor shall it protect the operator of any such vehicle from
the consequence of an arbitrary exercise of such right of way. Upon the
approach of any ambulance or police or fire department vehicle giving
audible signal by bell, siren or exhaust whistle, the operator or every other
vehicle shall immediately drive the same to a position as near as possible
and parallel to the right hand edge or curb of the highway, clear of any
intersection of highways, and shall stop and remain in such position
unless otherwise directed by a police or traffic officer until the ambulance,
police or fire department vehicle shall have passed. It shall be unlawful
for the operator of any vehicle other than one on official business to follow
any fire apparatus traveling in response to a fire alarm closer than six
hundred feet or to drive into or park such vehicle within six hundred feet
to the place where fire apparatus has stopped in answer to a fire alarm.

The State Roads Commission is hereby authorized and directed to desig-
nate main traveled or through highways by erecting at the entrances thereto
from intersecting highways signs notifying drivers of vehicles to come to
a full stop before entering or crossing such designated highway, and when-
ever any such signs have been so erected, it shall be unlawful for the
operator of any vehicle to fail to stop in obedience thereto, except when
traffic at such marked intersection is controlled by traffic signals or officers.
All such signs shall be illuminated at night or so placed as to be illumi-
nated by the headlights of an approaching vehicle or by street lights. The
