Short answer:
 

Yes, radar detectors are legal in New York for private passenger vehicles. If you’re driving your own car, SUV, or pickup truck in New York State, you are allowed to use a radar detector. However, there are some strict exceptions, and misusing these devices can still land you in trouble.

Below, we’ll explain exactly who can (and can’t) use radar detectors in New York, plus all the important laws, restrictions, and best practices to stay compliant.

‍

Who Can Use a Radar Detector in New York?

• Private vehicle owners:
  You can legally install and use a radar detector in your personal vehicle throughout New York State. This means your family car, your daily commuter, or even your Sunday convertible are all fair game.
  
  
• No restrictions on placement:
  New York does not have a state law against mounting radar detectors on your windshield or dashboard. Just make sure it doesn’t block your view or distract you from driving safely.
  
  

When Are Radar Detectors Not Legal in New York?

There are several situations where radar detectors are absolutely not allowed in New York:

1. Commercial Vehicles (Over 10,000 Pounds)
Federal law prohibits radar detectors in any commercial motor vehicle weighing over 10,000 lbs—and New York enforces this rule. If you’re driving a big rig, delivery truck, or other commercial vehicle, leave the radar detector at home.

2. Radar and Laser Jammers
Unlike detectors, radar jammers and laser jammers are 100% illegal in New York (and most other states). Jammers actively interfere with police speed-measuring equipment, and using them can lead to steep fines or even criminal charges.

3. Federal Property and Military Bases
Radar detectors are banned on federal installations, like military bases or certain national parks in New York. Always check posted signs and rules when entering these areas—devices may be confiscated.

‍

Why Are Radar Detectors Legal for Most New York Drivers?

• Radar guns can be inaccurate or misused, so radar detectors let drivers be more aware of speed enforcement zones.
  
  
• Passive radar detectors (unlike jammers) do not interfere with police equipment.
  
  
• New York State believes drivers should have the right to monitor their surroundings—but not to speed.
  
  

Important: Using a radar detector isn’t an excuse to break the law. If you’re caught speeding, the device won’t protect you from a ticket!
