It shall be the duty of officers designated by the Chief of
Police to enforce the provisions of these 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 rules and orders, provided that, in the event of a fire or
other emergency, to expedite traffic or safeguard pedestrians, officers
of the Police Department may direct traffic as conditions may require,
notwithstanding the provisions of these rules and orders.
The Chief of Police or his designee is hereby authorized to
close temporarily any street or highway in an impending or existing
emergency, construction, lawful assemblage, demonstration or procession.
The Chief of Police or his designee 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; or for construction or repairs for up
to 30 days, provided there is a reasonable justification of the closing
of such street. Vehicles parked in places where parking is prohibited
temporarily may be moved by or under the direction of an officer.
The Chief of Police shall make the final determination for private
duty detail officers in the event of any construction, repair or maintenance
in, upon, or adjacent to any street or highway.
The provisions of these 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 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.
