A great idea out of Tennessee that didn’t make it past state legislators. A bill from 2006 would have required towns that generates more than half of its revenue from speeding tickets to use blue-colored speed limit signage. The motivation behind this bill was certain towns that intentionally lower speed limits to unreasonably low levels in order to generate more revenue from speeding tickets. This undermines the purpose of speed limits, which is supposed to be for public safety, not government revenue. But we all know how that goes.
