We have had that law in TN for a few years now. CD599 has it right, but also pay attention to what I underlined above. The time of day and the amount of traffic plays a big part of it. It's one thing if it's at 2 in the morning with no other cars in sight. But if it is during the day or a time when a ton of other vehicles are present, running the red light regardless of coming to a complete stop or not, just because you didn't want to wait for the light to change isn't an excuse and will likely land you a ticket. Common sense is a factor here. Don't take advantage of the new ruling. I doubt any judge will dismiss a case if the officer can prove the motorcyclist had cars behind him which would have triggered the sensor and the rider did not give ample time for the light to change.Let's be real clear about this. You can't "run" a red light with this new law. You can only PROCEED after stopping at a red light if it won't change to green. Don't want anybody getting hurt.
