I'm sure this law varies from state to state, Alabama also has a clause saying somthing to the effect of unreasonable time or several rotations of light changing for other directions and not yours. It is a problem when you are the only vehicle(motorcycle) on one of the magnetic sensor lights,,,,,I just recently had this problem and I kinda lost my cool with the
LEO, I knew he had a camera running in his car and his microphone could catch our conversation so I told him in a tastefull manner that if he had a problem with me running the red light then I would see him in court, he wrote me a warning and I ripped it up in front of him.......The situation was stupid, I just got through detailing my bike, I wanted to take it for a spin, OK, it's 10pm during the week, nobody is out and downtown is like a ghost town. Of all redlights I stop at the one right in front of the police station and I have my left signal on...I'm going to make a ride by the river boatlanding downtown and back up to my house. I wait....wait...wait...ok, nobody has passed by, nothing comming, police station is dark except for the dispatch office, several LEO cars always parked outside, but one had an officer who was sitting there watching me the whole time, he waits till I get two blocks away then come out to get me....I asked him did he see how long I sat there, and his reply was next time turn right at the red,,MORON!.....I also had my blue leds on! He never said a word about them!!!
