If you’ve got a radar detector sitting on your dash, or you’ve been thinking about picking one up before your next run up I-81, this is worth a couple of minutes of your time. New York’s rule isn’t a flat yes or no. It depends on what you’re driving.
New York Radar Detector Law Bans Them in Heavy and Commercial Vehicles
The section of New York’s Vehicle and Traffic Law that covers detectors is short, and it’s aimed squarely at big vehicles. Radar and laser detectors can’t be used in any vehicle with a gross vehicle weight rating over 18,000 pounds. For commercial vehicles, the cutoff drops to anything over 10,000 pounds.
In everyday terms, the tractor-trailer hauling freight down I-86 is covered, as are many box trucks and larger delivery vehicles. If you drive a work truck and aren’t sure where yours lands, the weight rating is usually printed on a sticker inside the driver’s door.
Why a Plugged-In Radar Detector in New York Counts as Using It
This is the part that catches drivers off guard. Owning a radar detector isn’t illegal in New York. But in one of those heavier vehicles, if the detector is connected to power and working, the law presumes the driver was using it. Nobody has to prove it was actually beeping.
You can fight that presumption, but you’ll need credible, reliable evidence that the detector wasn’t in use. Just saying it was switched off isn’t going to carry much weight.

New York Fines for Radar Detector Violations Run $25 to $100
Getting caught with one in a heavy vehicle is a traffic infraction, and the fine ranges from $25 to $100. That won’t empty anybody’s wallet, but it’s still a ticket.
The law also doesn’t give police the go-ahead to take the detector from you. Seizing it would have to be allowed under some other law.
Federal Rules Add Another Layer for New York Truck Drivers
State law isn’t the only thing truckers have to think about. A federal motor carrier regulation says a driver can’t use a radar detector in a commercial motor vehicle, and can’t operate one that has a detector in it at all. So for drivers who fall under those federal rules, simply having one in the cab is a problem, plugged in or not. Trucking companies aren’t allowed to let it slide, either.
Radar Detectors Are Legal in Regular Passenger Cars in New York
Now the good news for the rest of us. If you’re driving your own car or pickup and it’s not a commercial vehicle, you’re fine. New York doesn’t ban radar or laser detectors for everyday drivers.
Legal doesn’t mean it’s a free pass, though. A detector only tells you radar is nearby. If you’ve already been clocked by the time it goes off, it won’t help much.
Radar Jammers Are Illegal in New York and Everywhere Else
Detectors and jammers often get lumped together, but they’re very different. A detector just listens. A jammer sends out a signal meant to interfere with the radar gun, and the FCC says it’s a violation of federal law to use a device that blocks or jams police radar. That applies no matter what you drive.
One more thing if you’re headed out of state. Every state sets its own rules on detectors, so it’s worth looking up the law wherever you’re going before you leave the driveway.
