I don't know about other places, but on the highway in Michigan near construction sites they sometimes have signs saying something like "If you injure a worker, it's a $5000 fine and up to 25 years in jail".
Note the precedence of the $5000 fine before the 25 years of jail time. Clearly the Michigan DOT thinks that fines and jail time are necessary incentives to not kill or harm construction workers.
