My question involves a moving violation in the state of Alabama.

I think I may have run a red light today... although I'm not sure, as I didn't see when the light changed.

Anyways, I didn't get a ticket on the way home, so I assume no one saw, at least not a human I assume. There were several cops in the area... so maybe they didn't give a shit? (Or maybe I was already in the intersection... don't know.)

My question is, for how long can they actually pull me over for that? Since I didn't get a ticket, there should be some sort of statute of limitations right? (They also have no way of proving I drove the car at that time either... but still...)
