Construction Worker Bounty

My wife and I traveled to Kansas City, Missouri today to attend a Seminar for Credit Unions. Just as we passed into Missouri from Iowa we saw the "dreaded orange cones" announcing road construction. There were the typical signs, "Slow Down", "Speed Limit 55 MPH", and "Fines Double in Construction Zones".

One sign however caught my eye, as I have never seen it before. It read, "Slow Down - $10,000 fine, AND you lose your license if you hit a construction worker."

Sounds like a bounty on highway workers..., and, what happens if the worker has reached the end of his rope and throws himself in front of a vehicle? Who pays the fine? Is it shared?
