§ 1144. Operation of vehicles on approach of authorized emergency
vehicles. (a) Upon the immediate approach of an authorized emergency
vehicle equipped with at least one lighted lamp exhibiting red light

bicycle when operated as an authorized emergency vehicle, and when
audible signals are sounded from any said vehicle by siren, exhaust
whistle, bell, air-horn or electronic equivalent; the driver of every
other vehicle shall yield the right of way and shall immediately drive
to a position parallel to, and as close as possible to the right-hand
edge or curb of the roadway, or to either edge of a one-way roadway
three or more lanes in width, clear of any intersection, and shall stop
and remain in such position until the authorized emergency vehicle has
passed, unless otherwise directed by a police officer.

(b) This section shall not operate to relieve the driver of an
authorized emergency vehicle from the duty to drive with reasonable care
for all persons using the highway.
