It shall be the duty of the Police Officers to enforce the provisions
of these rules and orders. Police Officers are hereby authorized to
direct all traffic either in person or by means of visible or audible
signal in conformance with the provisions of these rules and orders,
provided that in the event of a fire or other emergency to expedite
traffic or safeguard pedestrians, officers of the Police or Fire Department
may direct traffic, as conditions may require, notwithstanding the
provisions of these rules and orders.
The police may close temporarily any street or highway in an
impending or existing emergency, or for any lawful assemblage, demonstration
or procession provided there is reasonable justification for the closing
of such street.
The police may prohibit, temporarily, parking on any street
or highway or part thereof in an impending or existing emergency,
or for a lawful assemblage, demonstration or procession provided there
is reasonable justification for such prohibition. Vehicles parked
in places where parking is prohibited temporarily may be moved by
or under the direction of an officer.
The provisions of these rules and orders shall not apply to
operators actually engaged in work upon a street or highway closed
to travel or under construction or repair, to officers when engaged
in the performance of public duties nor to drivers of emergency vehicles
while operating in an emergency and in performance of public duties
when the nature of the work of any of these necessitates a departure
from any part of these rules and orders. These exemptions shall not,
however, protect the driver of any vehicle from the consequences of
a reckless disregard of the safety of others.
