When you get a drivers licence you sign a contract that you agree to obey all traffic laws, or run the risk of getting fined and possibly losing your driving privileges. Does that mean I always go the limit or under? Do my tires come to a complete stop at every stop sign?
I think theres a huge differences between driving 68 on the freeway in a 65 zone, and doing 125 through a school zone while chugging jack daniels.
Of course there's a difference. Why do people bring these moot points up all the time? The point is, and always has been, that if some moron state trooper wanted to give you a ticket for going 68 in a 65 he could. You would most probably get it dismissed, but that doesn't mean he doesn't have the right to give you a ticket....
