I agree. Its been a pet peeve of mine that people drive around with yellow lights flashing for no reason.If the cops drove around with the red and blue going after a while people would ignore them. When I was a kid yellow lights were on towtrucks when they were towing a car to warn other motorists they were working. Id like to see the no yellow in more states.I doubt they would lie about the law. And I don't think there is any reason to run your yellow/flashing lights between jobs.
