Section § 28150

Explanation

This law prohibits any vehicle from having a device that can mess with police radar or laser speed measuring tools. It's illegal for anyone to use, buy, or sell these gadgets. Break this rule, and it's usually just a minor offense, unless you have four or more devices, then it's a more serious crime. But if you have a federal license, you can transport these devices as long as you have the license on you while doing so.
