Working on the road can be very dangerous. I was a supervisor of a work crew of individuals who owed the state time and when we would put out our warning signs, I swear people would speed up instead of slow down and instead of moving over, they would move closer to the edge of the road. We had a supervisor who was killed on the job by a tire that came off of a semi. It bounced over a guard rail and took him straight out of this world.
