Todays world, anyone with a badge and gun call all the shots..
Ron Skeen is the only person I know that has ever, EVER been given a ticket.....(speeding) Any ticket!!!
I've been maybe 50-60k and never been stopped. Its not to easy to pull a 70' rig on the side of any road....Just to check if a passenger is drinking.
