Radar Detectors in New Jersey: Can You Get a Ticket?

Recently, a client of ours was charged with obstructing his windshield with a radar detector. This came of interest to me because I always use a radar detector while driving in the State of New Jersey.

After reviewing the applicable NJ law, it appears that it would be difficult for a police officer or prosecutor in New Jersey to prove the violation. The section of the statute which I believe that the police officer made reference to is: “No person shall drive any vehicle so constructed, equipped or loaded as to unduly interfere with the driver’s vision to the front and to the sides.”

The question then is…what does “unduly interfere” mean?

The State of New Jersey requires its drivers to have a rearview mirror and an inspection sticker posted on the windshield. How can they say that you can’t have a small radar detector attached to the windshield? Most people would agree that a radar detector does not block a driver’s vision in any significant amount.

I believe it is just another charge that an unhappy police officer can tag you with. I have not taken this violation to trial yet because may times the prosecutor will merge the violation or drop it in court.
