If you’re driving in New York, you may wonder whether using a radar detector is legal. The short answer? Yes, but with restrictions. While private vehicles can legally use radar detectors, commercial vehicles over 10,000 pounds are strictly prohibited from using them. If you’re a truck driver or operate a commercial vehicle, getting caught with a radar detector could lead to fines, penalties, and even CDL points—jeopardizing your ability to drive professionally.

Beyond commercial restrictions, radar jammers—devices that actively interfere with police radar—are completely illegal in New York and could result in criminal charges. Additionally, even if you legally use a radar detector, improper placement (such as mounting it on your windshield) could lead to a ticket for obstructing your view.

If you’re facing a ticket related to radar detector use—especially in a commercial vehicle—don’t take chances. Traffic violations can have serious consequences, including license suspension and financial penalties. Speaking with a New York traffic attorney can help you understand your rights, fight unjust fines, and potentially reduce or dismiss penalties.
