Washington, D. C.

Everywhere else you are usually inside. The clear. But” usually” carries. Some fine print, because a few states add their own rules.
States with Placement Rules (not limited)

That’s not suitable- a handful of states Adjust where you can mount. Your detector, Though the device itself remains legal.
California
Radar detectors are legal, but you can’t ride them through the windshield.
Place the device But the dashboard So instead if you petition,“ Is radar detectors legal in California?”, Yes, just watch where you progress.
Minnesota
Same windshield- mounting restriction Seam California.
The detector itself is completely legal. The mounting location is not.
Iowa
Radar detectors are legal, and the rule Here’s more general, Your device cannot block the bus, your view of the road Or a mirror?
It’s less a specific mounting ban And more a common- sense placement rule.
Lawmakers created these rules for one reason: Anything is an obstacle to your forward view, Even something small, creates a safety risk.
