You may have noticed runaway truck lanes while driving in the mountains. These gravel-filled lanes are designed to stop trucks
that have lost their brakes on mountain grades. Typically, such a lane is horizontal (if possible) and about 34.0 m long. Think of
the ground as exerting a frictional drag force on the truck.
