It shall be the duty of officers designated by the Chief of
Police to enforce the provisions of these Traffic Rules and Orders.
Such 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 Traffic 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 Traffic Rules and Orders.
The Chief of Police is hereby authorized to close temporarily
any street or highway in an impending or existing emergency, or for
any lawful assemblage, demonstration or procession.
The Chief of Police is hereby authorized to 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.
Vehicles parked in places where parking is prohibited temporarily
may be moved by or under the direction of an officer.
The provisions of these Traffic Rules and Orders shall not apply
to drivers 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 necessitate a departure
from any part of these Traffic 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.
