Are these states that are listed still legal to use personal radar devices? 2010.
Thank You

Also make sure you do not hang anything (therefore neither the radar detector) on the windshield in CA ... so if you can and works keep it somewhere else ...

I have and use an "Escort X50 in my work van, and it is a commercial vehicle. Is it illegal to use? And why? Thank you in advance.

Dear Jeff, can you kindly advise I have Whistler 78 pro. Will it work properly in US?
Radar detectors are illegal in Washington DC

If I fly in to US through Washington can I have problems for keeping it in My Lagguage?

I will use it in Florida

The use of radar JAMMERS is illegal in , but not radar detectors....

Lori-
Before posting, be sure to read your source! It clearly states that radar JAMMERS are illegal, and that radar detectors are illegal in COMMERCIAL vehicles. The law states that people with privately owned vehicles MAY use and posses radar detectors, not radar jammers.

Hi ,
I was wondering if radar detectors are legal in NJ, if they are can you please point me to right statue # so I can read for myself. People say it is legal but nobody is showing me proof from NJ government official website.

Thank you

Sincerely ,

I was wondering this the other day, since we were going on vacation. Thanks for the post.

there is a federal law against the use of radar detectors over 10,000lbs

Hi Jack, fortunately, most radar detectors don't weigh that much.
