Commercial Vehicles

In contrast to private vehicles, commercial vehicles are restricted from using radar detectors in Wisconsin.

Our research indicates that this prohibition aligns with federal safety regulations, which aim to maintain high standards in commercial transportation. Penalties for non-compliance can include hefty fines and points against a commercial driver's license.

At Escort Radar, we stress the importance of following these legal requirements.

In Which States Are Radar Detectors Illegal?

While radar detectors are legal in many parts of the United States, certain states have imposed bans or restrictions on their use.

Here is what you need to know.

Washington D.C.

Our findings show that the use of radar detectors is prohibited in all vehicles in Washington D.C..

This strict stance is part of a broader initiative to enforce speed limits and reduce traffic incidents in the capital area.

For those traveling to or through Washington D.C., it's advisable to remove and stow your radar detectors to comply with local laws.


Similarly, Virginia maintains a complete ban on radar detectors for all vehicles. The state's enforcement is rigorous, and violations can result in fines and confiscation of the radar detector.

If your travel plans include Virginia, we recommend deactivating and storing your radar detectors before entering the state boundaries.

Mounting Radar Detectors in Wisconsin

While you are free to use radar detectors in your private vehicle, there are specific guidelines on how they should be mounted in Wisconsin.

The key rule to follow is that the device must not obstruct the driver's view of the road. You can legally mount radar detectors on your windshield in Wisconsin, as long as the placement doesn't interfere with your line of sight.

At Escort Radar, we recommend mounting the detector near the bottom of the windshield or on the dashboard to ensure compliance.
