Here in the Carolinas, 15 over can get your license suspended for 30 days on a first offense. Cops typically won't bother you as long as your no more the 10 over the posted speed limit, school zones being the exception. Any form of speeding in a school zone is equivalent to a mortal sin! And I'm okay with that!

The best incident I ever encountered was a stop for speeding just south of Columbus, Ohio. Deputy sheriff said I was doing 69 in a 55 zone. Having seen my wife & 2 boys in the car (1987 Cougar XR7), he asked why I was in such a hurry. I responded that speed limits were essentially for those folks incapable of handling a car at higher speeds and that wasn't the case for me! He got a great laugh out of that, said they would talk about me at shift change that evening, and then wrote me a ticket! Never did come back on my NC license. To this day, I consider myself lucky!

And I'm in agreement with others regarding left lane drivers. The Europeans are more respectful of highway driving etiquette typically using the left lane only for passing. (Note: But even that trait is slowly diminishing.) But here in the States, the trucks have torn up the RH lane so much, that many folks use the LH lane just to keep from being "hammered" all the time. (Note: Really a complex issue of excessive traffic in RH lane, increased car density vs. original design specs, truck load carrying capabilities increasing over the years, along with insufficient funding for road maintenance. Trucks aren't the sole source of this problem.) I don't care if someone wants to drive in the LH lane. But be respectful of a car approaching from behind, move over to allow the pass, and then move back to continue on. Near the end of a month, law enforcement is not above pulling you over for passing on the RH side, which is considered unsafe driving practice in most states.

And it's going to get worse as States don't have funding to maintain the highway system and the trucks will eventually move over to the left on open roadways. I would! And here is SC, I think the state driving manual states that on a 4-lane divided highway, it's allowed to drive in either lane. So they have a right to be over there!
