a) Dukes of Hazzard Theme Park

b) Failed attempt to build a road over the mountain

c) Runaway truck ramp

Answer: C.

A runaway truck ramp, runaway truck lane, escape lane, emergency escape ramp or truck arrester bed is a traffic device that enables vehicles that are having braking problems to safely stop. It is typically a long, sand or gravel-filled lane adjacent to a road with a steep grade, and is designed to accommodate large trucks. The deep gravel allows the truck’s momentum to be dissipated in a controlled and relatively harmless way, allowing the operator to stop it safely.
