It shall be the duty of officers designated
by the Chief of Police to enforce the provisions of these regulations.
Such officers are hereby authorized to direct all traffic, either
in person or by means of a visible or audible signal, in conformance
with the provisions of these regulations, 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 regulations.
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 regulations 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 regulations. These exemptions shall not, however,
protect the driver of any vehicle from the consequences of a reckless
disregard of the safety of others.
