state coffers are low.
Yep.
When this “flashing light” law first went through in my state, the police set up a series of speed traps.
Pull over one driver for speeding above the posted limit on 59. Subsequent to that was another officer stationed to pull over anyone in the adjacent lane driving the speed limit (and not 20 BELOW the posted limit). And same with another officer in tandem after that waiting to pull over someone adjacent to THAT shoulder lane.
