I see these plastered all over Ohio and Michigan (and no wonder with all the goddamn construction going on).
Basically I have three problems with this sign. First of all, the amount of jail time is way out of proportion with the fine. If it had read "up to 15 years" then it would have been different. But 15 years? I've seen people get less time for outright murder. Here they are saying you could just run over the guys' big toe and you're in the slammer till 2025.
Secondly, it says "injure or kill a worker" - same fine. The means if you hit him you might as well kill him because the fine will be exactly the same.
But perhaps most odious, is the fact that the sign fails to consider that the injury may be the construction worker's fault. Construction work is one of the most entitled jobs out there. They take chances, they pull out in traffic, they talk on cell phones while on the job. Basically, they act as if the construction site is their own personal little playground and act accordingly.
I'm sure you've seen some of these workers acting pretty belligerent during the many times you've been snarled in traffic. (When they're not just lazing around that is). While it could be argued that reckless driving may cause the majority of the worker injuries, its certainly not too much of a stretch that a significant number are caused by the worker's own negligence or irresponsible behavior. The fact that the sign fails to consider that just argues all the more the sheer arrogance of the highway construction industry as well as the hypocrisy and arrogance of the agencies that award the construction contracts and make these signs.
