Dash cams are legal in New Jersey, but you must follow specific rules about where you mount them and how you record audio. If you do, your footage can usually be used as evidence in traffic or accident cases.
Where you can mount a dash cam
- No windshield obstruction: New Jersey bans any non‑transparent sign, sticker, or object on the front windshield or driver‑side front windows that blocks your clear view.
- Safe placement: The safest legal spot is on the dashboard, often on the passenger side or behind the rearview mirror, so it doesn’t cut into the driver’s line of sight.
If your dash cam blocks visibility, an officer can treat it as a violation of New Jersey’s clear‑view windshield rules, which may lead to a traffic citation.
Video recording rules
- Video in public: New Jersey allows you to record video of the roadway and public spaces from your car; you generally do not need a person’s permission to film them in public.
- Evidence in court: Dash‑cam footage is usually admissible in NJ courts if it is relevant, unaltered, and the date, time, and location can be verified or authenticated.
Audio recording and “one‑party consent”
- New Jersey is a “one‑party consent” wiretapping state: you can legally record audio from a conversation as long as you are a participant in that conversation (e.g., you are driving and talking to passengers).
- Secretly recording a private conversation in your car that you are not part of (for example, passengers talking while you are away) can violate the New Jersey Wiretapping and Electronic Surveillance Control Act and may be a criminal offense.
Best‑practice tips for NJ drivers
- Mount the camera on the dashboard or passenger‑side upper windshield area, keeping the driver’s view unobstructed.
- If your dash cam records audio, assume conversations in your car can be captured and avoid using recordings in ways that invade others’ privacy.
- If you are in an accident, preserve the footage and, if needed, consult a New Jersey accident attorney who can help determine whether it helps or hurts your case.
