Radar Detector Laws Utah: What Drivers Should Know

ByBNW TEAM

Radar detectors are electronic devices that drivers use to detect radio or laser signals that are emitted by Utah police to maintain speed limits on the roads. 

If you are someone who drives frequently, you must have at least thought about buying a radar detector so you can avoid getting a speeding ticket.

But first, you should know whether it’s legal to use one in Utah. The good news is Utah is quite permissive compared to other states like Virginia, where using a radar detector is strictly banned. 

But wait—there’s more! Being legal doesn’t mean no rules will be applicable. This guide covers almost everything that Utah drivers should know before placing a radar detector on their car’s windshield.  

Are Radar Detectors Legal In Utah?

Yes, radar detectors are legal to use in standard and private passenger vehicles. Whether you drive a sedan, a truck, or a motorcycle, you can use this device to alert you whenever you are approaching police radar.

  • For Personal Vehicles

You don’t need any special registration to use a radar detector in your personally owned vehicle. Drivers can use it to avoid speeding tickets without breaking any state law. So, long story short, you can buy one, install it, and use it while driving on Utah highways without any second thought.

  • For Commercial Vehicles

Remember, commercial vehicles have a different story. Under Utah law, it’s illegal to use radar detectors if you drive a vehicle for commercial purposes. Commercial vehicles may include semi-trucks, delivery vehicles, or any kind of vehicle that is used to transport goods in the course of business.

All in all, if you drive for a living like trucking or ride-sharing, it’s wise to leave your radar detector at home. Because it can lead to heavy fines and legal complications for both you and your employer if you get caught using one on the highway.

Does Using A Detector Affect A Speeding Ticket?

No! Using a detector doesn’t stop a police officer from issuing you a speeding ticket. 

In fact, it can negatively influence an officer’s discretion at a signal, and it becomes less likely that he will let you go with just a verbal warning. If a speeding incident also leads to a crash or injury, speaking with a car accident attorney can help you understand your legal options.

Here are some possible Utah-based scenarios you might face:

  1. You cannot use the failure of a radar detector to alert as a valid excuse in your defense to dismiss the fine charge in court.
  2. Possessing a radar detector that is near military bases can even lead to separate fines or even confiscation of the device.
  3. Utah uses fixed-wing aircraft and helicopters for air patrol as well that clock your speed over timed distances, leaving your radar detector completely useless.
  4. Officers also use laser guns because their beams are highly targeted, and your device usually goes off when a laser strikes your vehicle and logs your speed.

What Are The Penalties For Violating The Law?

Because Utah allows you to use standard radar detectors, you won’t legally face penalties just because you have one on your windshield. 

However, important laws and consequences of breaking them are discussed below: 

State Infraction

According to Utah Code 41-6a-604, driving a vehicle that has a device designed to jam or interfere with police radar falls under a state infraction. 

The violation may result in a fine up to $750. First-time offenses are usually settled between $50 and $250. Fortunately, an infraction does not carry jail sentences.

But if your device specifically jams active radar frequencies regulated by the Federal Communications Commission (FCC), then this offense will fall under federal law. Its penalty can lead to up to a $50,000 fine and 5 years in jail.

Windshield Obstruction Tickets

Under Utah Code 41-6aa-1635, you cannot mount a radar detector anywhere that blocks your view of the road. Which means a police officer can still write you a windshield obstruction ticket if you place your perfectly working and legal device in the way of your sight while driving. 

Fortunately, it’s just a minor traffic infraction that is settled with a small fine and an instruction to clear your dashboard.

Commercial Vehicles

Under federal regulations 49 CFR 392.71, when a commercial vehicle, especially those over 10,000 pounds, breaks the radar detector law, it automatically becomes a big deal. Because driving heavy vehicles also comes with heavy rules. 

Federal law strictly prohibits using a radar detector on commercial vehicles. So even if your device is turned off, unplugged, or hidden in a bag, it will still be illegal. 

Additionally, you may get in trouble if police officers find a radar jammer in your cab or truck. Consequences include heavy fines that drivers usually need to pay out of their pockets and device confiscation. 

5 Tips to Avoid Speeding Tickets

The most reliable way to avoid speeding tickets in Utah is always to drive within a safer range of the speed limit. Safe driving also reduces the risk of serious crashes, including head-on collisions, which can result in severe injuries.

But you can adopt these habits to avoid getting a speeding ticket: 

  1. Use cruise control on highways, but only if road conditions allow you to.
  2. Watch out for changing speed limits near schools, hospitals, or construction zones.
  3. Try to leave earlier so you are not tempted to rush on your way.
  4. Keep a tab on your speed when you are passing traffic, descending a hill, or merging with other cars on the road.
  5. Always slow down when you see bad weather, reduced visibility, heavy traffic, or a road under construction.

Conclusion

If you own a personal vehicle, you can use a radar detector without any legal worry. But if you drive for a living, you should remember detectors are not allowed in commercial vehicles. 

Otherwise, you can face heavy fines in the form of speeding tickets from Utah traffic police. However, if you ever get involved in any car accident because of crossing a speed limit, you can contact Cockayne Law to get free legal guidance. 

FAQs

Are radar jammers legal in Utah?

No, Utah law strictly prohibits driving a vehicle on a highway with a radar jamming device. It is considered an infraction according to federal law under current Utah Code 41-6a-609. 

Can I get a ticket for using a radar detector?

No, as using a radar detector in your personal vehicle is legal in Utah, you won’t get a ticket for having one in your vehicle. However, if you place it on the windshield where it might block your road view, you can get a windshield obstruction ticket from Utah traffic police.

Does a radar detector help fight a speeding ticket?

Not necessarily! A radar detector just alerts the driver whenever you step into radio signals emitted by Utah police. This device will not be counted as proof that you were driving within the speed limit. 

Can police confiscate a radar detector?

It depends on your situation and applicable law. A police officer can’t confiscate your device just for being there in your personal car. But if you are caught using one in a commercial vehicle, Utah police can confiscate your device because it’s prohibited.
