Safe Driving第 58 / 120 题
On a mountain grade you see a sign for a runaway vehicle ramp ahead. What is its purpose?
a.It is a required weigh station for loaded trucks
b.It is a parking area for chaining up in winter
c.It is an escape route designed to stop a vehicle that has lost braking ability
d.It is a mandatory rest stop for descending vehicles
解析
Escape ramps use gravel beds or upgrades to stop a vehicle whose brakes have faded or failed, and using one is far better than continuing downhill. They are not weigh stations, chain-up areas, or required rest stops.
