In looking for info on Stop Sign laws, I am reminded of another question that has always nagged at me...
So many people do their stop sign stop well into the intersection. Especially when they notice the police officer monitoring the intersection they had not planned on fully stopping at.
If I am behind one of these people - they "stop" a car length or so _after_ the stop line. I come to a complete stop at the same time they do, just at or a foot or so behind the stop line. (Where you would normally expect to stop for a stop sign).
Do I have to stop again, or for longer than usual? If a cop is there, I do - just to make sure. The guy in front of me never gets pulled over, even though he technically didn't stop where he was supposed to. My luck, I would get the ticket even though I am pretty sure I would be "right" in this case.
Note - in this scenario, there are no other vehicles crossing my direction of travel.
