New Jersey bicycle laws treat a bike as a vehicle, which means you follow the same traffic rules as a driver and carry specific equipment: a helmet if you’re under 17 (or riding any e-bike), a front white light and rear red light after dark, and a bell audible from 100 feet. Drivers must give you at least four feet when passing, and yes, you can be charged with DUI on a bicycle.
Helmet Requirements
Anyone under 17 must wear a properly fitted and fastened helmet while riding, sitting as a passenger, occupying an attached child seat, or being towed in a trailer.1Justia. New Jersey Code 39-4-10.1 – Bicycle Helmets, Requirements The helmet has to meet the ANSI Z90.4 bicycle helmet standard or the Snell Memorial Foundation’s 1990 standard.
Adults on a standard pedal bicycle are not required to wear a helmet. One important exception: every electric bicycle rider must wear a helmet regardless of age.2New Jersey Motor Vehicle Commission. E-bike
Lights, Reflectors, and a Bell
A bicycle ridden at night must have a front lamp emitting a white light visible from at least 500 feet and a rear lamp emitting a red light visible from at least 500 feet.3Justia. New Jersey Code 39-4-10 – Lights and Reflectors on Bicycles A rear red reflector is optional and, if used, must be a type approved by the Division of Motor Vehicles.
Every bicycle also needs a bell or other audible signal that can be heard from at least 100 feet. Sirens and whistles are prohibited.4Justia. New Jersey Code 39-4-11 – Audible Signal This rule applies all the time, not just after dark, and covers riding on streets, bike paths, and park trails.
Traffic Rules Every Cyclist Follows
Because a bicycle is a vehicle under state law, you must obey traffic signals, stop signs, lane markings, and yield requirements the same way a driver does, and you must ride in the same direction as traffic.5Justia. New Jersey Code 39-4-14.1 – Rights, Duties of Bicycle Riders on Roadways, Exemptions
Where to Ride in the Lane
You must ride as near to the right side of the roadway as practicable, with four situations that let you move left:6Justia. New Jersey Code 39-4-14.2 – Keeping to Right Side of Roadway
- Making a left turn.
- Avoiding debris, storm drains, or other hazards on the right.
- Passing a slower vehicle.
- Traveling at the same speed as surrounding traffic, in which case you may use any available lane.
Two cyclists may ride side by side if they are not impeding traffic. Once flow is affected, they must switch to single file.
Hand Signals
Signal continuously for the last 100 feet before a turn.7Justia. New Jersey Code 39-4-126 – Signaling Turns and Stops All three signals use the left arm:
- Left turn: left arm extended straight out.
- Right turn: left arm extended upward at a 90-degree angle.
- Stopping or slowing: left arm extended downward.
Sidewalks and Bike Paths
State law does not settle sidewalk riding. Municipalities set their own rules, and some prohibit it in business districts while others allow it unless signs say otherwise. Check for posted signs or the local ordinance before riding on a sidewalk in an unfamiliar area. Bike paths and multi-use trails may carry their own posted rules, including speed limits and restrictions on certain e-bikes.
Electric Bicycle Rules
New Jersey’s definition of a “low-speed electric bicycle” is narrow: only pedal-assist bikes whose motor cuts off at 20 mph qualify, which lines up with what other states call a Class 1 e-bike. Throttle-assisted bikes and pedal-assist bikes that reach 28 mph are classified as motorized bicycles (mopeds) under state law, with different requirements.2New Jersey Motor Vehicle Commission. E-bike
- You must be at least 15 to operate an e-bike.
- Every e-bike rider must wear a helmet, no matter their age.
- Low-speed e-bikes may use bicycle paths, but local governments can restrict that access.
If you’re moving from a state that gives throttle-assist e-bikes the same freedoms as regular bicycles, New Jersey does not.
How Drivers Must Pass You
On a single-lane road, a motorist passing a cyclist or other vulnerable road user must leave at least four feet of clearance. If four feet is not possible on that stretch, the driver must slow to 25 mph and wait until it is safe to pass.8New Jersey Department of Transportation. Responsibilities, Pedestrian Safety
A violation carries a $100 fine when no one is hurt. If the pass causes bodily injury, the fine is $500 and the driver receives two motor vehicle penalty points.8New Jersey Department of Transportation. Responsibilities, Pedestrian Safety Cite the statute when you file a police report after a close call or collision.
Riding Under the Influence
You can be charged with DUI on a bicycle in New Jersey. The state DUI statute was written for motor vehicles, but in State v. Tehan a state appellate court held it applies to cyclists too, reasoning that riders share the same duties as drivers. Fines, community service, and jail time are on the table. The court did strike license revocation from the list of available penalties, because no licensing system exists for bicycles.9Justia. State v. Tehan
An impaired rider weaving through traffic can also be charged under the state’s disorderly conduct statute, which reaches anyone who recklessly creates a hazardous or physically dangerous condition serving no legitimate purpose.10Justia. New Jersey Code 2C-33-2 – Disorderly Conduct
Fines and Who Pays Them
Enforcement varies, and some violations end in warnings, especially for young riders.
For helmet violations, the rider under 17 gets a warning, not a fine. The penalty falls on the parent or legal guardian: up to $25 for a first offense and up to $100 for repeats, and only when it can be shown the parent failed to exercise reasonable supervision. The fine can be waived if the family shows proof that an approved helmet was owned at the time of the violation or has been purchased since.11Justia. New Jersey Code 39-4-10.2 – Violations, Warnings, Fines
Other infractions, like riding at night without lights, failing to signal, or running a stop sign, carry fines that track motor vehicle violations. A federal court schedule for New Jersey lists a $54 base fine for bicycle and roller skate violations by juveniles under 17.12United States District Court District of New Jersey. Appendix E – List of Petty Offenses and Minimum Fines Adult cyclists can expect similar or higher amounts, and reckless riding that causes a crash can lead to civil liability on top of any ticket.
