What Happens If You Get Pulled Over With Radar Detectors in Hawaii?

If you're within Hawaii's legal limits, a traffic stop shouldn't escalate over radar detectors. But "shouldn't" and "won't" are different things. Officers have discretion, and anything in plain view is fair game. Store it properly, know the exact legal limits, and keep proof of legal purchase if you can. Don't volunteer information you're not asked for.
