Passenger Vehicles vs. Commercial Vehicles
Passenger Vehicles
For personal vehicles such as sedans, hatchbacks, SUVs, and pickups, radar detectors are legal with no special state-level restrictions. Drivers simply need to ensure the device is mounted safely and does not block visibility.
Commercial Vehicles
Federal law prohibits radar detectors in many commercial vehicles, including:
- Vehicles over 10,000 pounds GVWR
- Vehicles transporting more than 9 passengers for hire
- Vehicles transporting more than 15 passengers not for hire
| Vehicle Type | Legal to Use? | Notes |
|---|---|---|
| Passenger vehicle | Yes | Legal statewide |
| Light duty personal pickup | Yes | Legal unless operated commercially |
| Commercial truck over 10,000 lbs | No | Federal law prohibits radar detectors |
| Buses and passenger carriers | No | Federal passenger transport rules apply |
Windshield Mounting Laws in Ohio
Ohio does not have a specific law that bans mounting a radar detector on the windshield. However, general obstruction rules apply, meaning the device cannot block the driver's clear view of the road.
Many drivers choose mirror-based mounts to avoid potential issues. These mounts offer several advantages:
- High and centered placement
- Cleaner sightlines
- Reduced vibration
- A more factory-like appearance
Laser Jammers and Radar Jammers in Ohio
Ohio prohibits devices that interfere with police laser or radar systems. This includes:
- Laser jammers
- Radar jammers
- Signal scramblers
Passive radar detectors are legal, but active jamming equipment is not.
How Ohio Enforces Radar Detector and Mounting Laws
In most cases, radar detector enforcement in Ohio focuses on:
- Commercial vehicle inspections
- Laser jammer violations
- Windshield obstruction issues
Police do not typically search for radar detectors in normal passenger cars, unless the device is mounted poorly or interfering with visibility.
