Even where the money apparently is being applied, I was sometimes mystified. Virtually all states have laws that double traffic fines in work areas. This was done in response to accidents that killed road workers. These workers are further protected by reduced speed limits, sometimes as much as 35 mph lower than the normal speed. The problem is that many of these "work areas" seem to be nothing more than a series of warning signs and a few cones or barrels. I'd crawl along for several miles waiting for the reason to appear, but there would be no workers, no equipment, no lane closures, no rough pavement, not even blockage of the shoulders. On multi-lane roads, some drivers would obediently slow to the posted work zone speeds, while others, especially as it became apparent that there were no workers or any reason for caution, would resume their normal pace, creating a dangerous speed difference. Some states only make work zones and related speed limits active when a sign's lights are flashing, which seems like a better and safer system.
