for the safety of all persons using the highway nor shall it protect the opera-
tor 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 of ¹ salvage corps vehicle giving audible signal by bell, siren or
exhaust whistle, the operator of 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 or salvage
corps 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 opera-
tor of any vehicle, including bicycle, to fail to stop in obedience thereto,
except when traffic at such marked intersection is controlled by traffic sig-
nals or officers. All such signs shall be illuminated at night or so placed
as to be illuminated by the headlights of an approaching vehicle or by
street lights. The operator of a vehicle, including bicycle, entering a high-
way so designated shall yield the right of way to all vehicles approaching
on such highway, provided that at the intersection of two highways so desig-
nated, all vehicles shall have the right of way over other vehicles approach-

limits of Baltimore City, the designation and marking of such main trav-
eled or through highways shall be made by the Police Commissioner of
Baltimore City.

No ordinance, rule or regulation of any municipality or county shall
change or abrogate in any way these provisions of the General Law with
