The Borough Council may, in its discretion, refuse to issue or renew, or may, after notice and hearing, suspend:
A. 
Any license of either class if the applicant or licensee has been once convicted of a crime in this or any other jurisdiction or convicted of being a disorderly person or of a violation of Title 39, Motor Vehicles and Traffic Regulation, of the Revised Statutes of New Jersey, or violates any provision of this chapter or has any judgment unsatisfied of record against him arising out of an automobile accident, or has made false answers in his application for such license or any renewal thereof, or has failed or fails to render prompt, safe and adequate taxicab or limousine service, or has not complied fully with all requirements of this chapter for such class of license.
B. 
Any taxicab or limousine driver's license if the licensee or applicant has in any degree contributed to any injury to person or damage to property arising out of negligent operation of a motor vehicle, or has any communicable or contagious disease.
C. 
Any taxicab or limousine owner's license if the motor vehicle licensed, by reason of unsafe or unsanitary condition, is dangerous to the safety or health of the occupants or others, or if the policy of insurance required by N.J.S.A. 48:16-3 has once lapsed or such coverage is not maintained at all times.
Each applicant granted a taxicab or limousine driver's license shall be issued a license card in evidence thereof, in a form approved by Borough Council and signed by the Borough Clerk in its behalf. Such license card shall at all times be prominently displayed and adequately protected in the interior of any taxicab or limousine operated by the licensee so that the face thereof shall at all times be in full view and plainly legible to any passenger seated on the rear seat of such taxicab or limousine. The license card shall at all times be and remain the property of the Borough and, on direction of Borough Council, shall at once be surrendered to the Borough Clerk. No taxicab or limousine driver's license card other than that of the licensee actually operating the taxicab or limousine at the time shall be displayed therein.
Each applicant granted a taxicab or limousine owner's license shall be issued a license plate, hereinafter referred to as a "Borough tag," made of such material and in such form as Borough Council shall see fit, which said Borough tag shall at all times be kept clearly legible and be displayed on the rear exterior portion of the taxicab or limousine thereby licensed, directly above or below the New Jersey state registration plate thereon. Said Borough tag shall at all times be and remain the property of the Borough and, on direction of Borough Council shall at once be surrendered to the Borough Clerk. The face of such Borough tag shall be illuminated by a suitable light so arranged as to throw a continuous steady illumination thereon during the entire period from one hour after sunset until one hour before sunrise.
