[Amended 1-14-1997 by G.O. No. 1-1997]
A. 
The provisions of this chapter shall apply to the driver of any vehicle owned by or used in the service of the United States government and this state, county or City, or any political subdivision of this state, county or City or any City or state agency, and it shall be unlawful for any such driver to violate any of the provisions of this chapter except as otherwise permitted in this chapter or by state statute.
B. 
All parking and traffic regulations shall apply to all elected and nonelected public employees and officials including all employees and officials of the United States government, the state, all of its political subdivisions, including any county, City or other municipality, including the City of Yonkers, except if the driver and/or vehicle are performing an official government function and on a specific emergency or activity which required the noncompliance with the traffic or parking regulation which would be otherwise applicable. Such an exemption must be demonstrated in detail by submission of a sworn affidavit by the driver of the vehicle and/or owner thereof which sets forth a specific emergency or activity and the government function involved. The affidavit shall be substantially in conformance with those promulgated by the Parking Violations Bureau, in accordance with the "Official Business Defense" regulations also promulgated. Each affidavit must be reviewed and approved by a hearing officer or by the Director of the Parking Violations Bureau.
A. 
The provisions of this chapter regulating the operation, parking and standing of vehicles shall apply to authorized emergency vehicles, as defined in this chapter, except as follows: A driver, when operating any such vehicle in an emergency, except when otherwise directed by a police officer, may:
(1) 
Park or stand notwithstanding the provisions of this chapter.
(2) 
Proceed past a red or stop signal or stop sign, but only after slowing down as may be necessary for safe operation.
(3) 
Exceed the prima facie speed limits so long as he does not endanger life or property.
(4) 
Disregard regulations governing direction of movement or turning in specified directions so long as he does not endanger life or property.
B. 
The foregoing exemptions shall not, however, protect the driver of any such vehicle from the consequences of his reckless disregard of the safety of others.
A. 
The driver of any vehicle and the motorman of any streetcar shall obey the instructions of any official traffic control device applicable thereto placed in accordance with the traffic ordinances of this City, unless otherwise directed by a police officer, subject to the exemptions granted the driver of an authorized emergency vehicle in this chapter.
B. 
No provision of this chapter for which signs are required shall be enforced against an alleged violator if, at the time and place of the alleged violation, an official sign is not in proper position and sufficiently legible to be seen by an ordinarily observant person. Whenever a particular section does not state that signs are required, such section shall be effective without signs being erected to give notice thereof.
Whenever authorized signs are erected indicating a zone of quiet, no person operating a motor vehicle within any such zone shall sound the horn or other warning device of said vehicle except in an emergency.
Whenever traffic shall be controlled by traffic control signals exhibiting different-colored lights successively, one at a time, or exhibiting the word "Walk," the following colors only shall be used and such lights and word shall indicate the following:
AMBER
Vehicular traffic facing the signal shall stop when an amber light is exhibited following a green signal; but when such stop cannot be made safely, vehicular traffic may proceed in a cautious manner through the intersection.
GREEN
Vehicular traffic facing the signal may proceed straight through or turn right or left, unless a sign at such place prohibits a right or left turn. Vehicular traffic shall yield the right-of-way to pedestrians lawfully within the intersection at the time such signal is exhibited. Pedestrians facing the signal may proceed across any marked or unmarked crosswalk.
RED
Vehicular traffic facing a red signal shall stop before entering the nearest crosswalk bordering the intersection at which the traffic control signal is located or at which a sign bearing the words "Stop on Red" is displayed and shall remain standing until the green signal shall be exhibited.
WALK
When the word "Walk" is exhibited by any traffic control signal, all vehicular traffic shall stop and remain standing to permit pedestrians to proceed across any marked or unmarked crosswalk.
It shall be unlawful for the directing officer or the operator of any railroad train to direct the operation of or to operate the same in such a manner as to prevent the use of any street for purposes of travel for a period of time longer than five minutes, except that this provision shall not apply to trains or cars in motion other than those engaged in switching. It shall be unlawful for any railroad train to stop within an intersection or on a crosswalk for the purpose of receiving or discharging passengers.
A. 
A traffic control signal shall regulate traffic only at the intersection where it is located, unless a sign bearing the words "Stop on Red" is conspicuously displayed at other intersections intended to be regulated by such traffic control signal.
B. 
The Traffic Engineer is hereby authorized to designate intersections, other than intersections at which traffic control signals are located, to be regulated by traffic control signals and to cause to be displayed at such intersections a sign bearing the words "Stop on Red."
It shall be unlawful for the driver of any vehicle to drive any such vehicle onto, past or across any crosswalk or street intersection where vehicles are directed to stop by traffic control lights or by "Stop on Red" signs contrary to or in disobedience of the directions indicated by such traffic control signals.
