Move over law enforcement
The county where I live includes 25 miles of interstate (covered by only 2 FD's, including mine which covers about 8 of that) and our deputies actually run sting operations at random times throughout the year. They will do a special traffic enforcement on the "I" with 2 deputies and when one of them has a speeder, the other will park just past that, and pull over cars that don't abide by the move over law. No warnings either,only tickets. It's great to see the special enforcement of it. After getting brushed by a sideview mirror on a call one time, anything PD can do to enforce the law is good in my eyes!!
