New Jersey Title 39 (Motor Vehicles and Traffic Regulation) does not address bicycles on sidewalks at the state level; the matter is left to municipalities under N.J. Stat. § 39:4-197. Newark, Jersey City, Hoboken, and Atlantic City each prohibit sidewalk riding by adults in their central business districts. Many smaller municipalities allow sidewalk riding citywide subject to a yield-to-pedestrians rule. Boardwalks have their own bike-hour ordinances along the Jersey Shore.
New Jersey's DWI statute (N.J.S.A. 39:4-50) applies only to operators of a 'motor vehicle.' New Jersey courts have held that bicycles are not motor vehicles for DWI purposes (State v. Tehan, 1989). A cyclist cannot be charged with DWI in New Jersey; disorderly-conduct or related offenses may still apply.
Front headlamp emitting a white light visible from at least 500 feet to the front.
Rear requirement
Rear light only
Rear spec
Red rear lamp visible from at least 500 feet to the rear (a reflector alone does not satisfy the statute — a lamp is mandatory). A red reflector may be added on top of the lamp.
Two abreast permitted on the roadway. N.J. Stat. § 39:4-14.5 prohibits riding more than two abreast except on paths or parts of roadways set aside for the exclusive use of bicycles.
Bicycles are prohibited on New Jersey Interstate highways (I-78, I-80, I-95, I-280, I-287, I-295, I-676) under NJDOT controlled-access regulations and on the New Jersey Turnpike, Garden State Parkway, and Atlantic City Expressway under their respective authority regulations. Conventional US and state routes (US-1, US-9, US-202, NJ-29) remain open. The Pulaski Skyway and the Hudson River crossings (Lincoln and Holland Tunnels, George Washington Bridge bike path) have separate rules — check the Port Authority bicycle access pages.
