Driving Safely第 54 / 60 题
On a long downgrade with a loaded tanker, what is the safest practice?
a.Ride the brakes continuously the whole way down
b.Shift into neutral and coast
c.Speed up to get to the bottom faster
d.Use a low gear and controlled braking to keep a safe, steady speed
解析
On a long, steep downgrade you should select a low gear before starting down and use engine braking to help control speed. Steady, controlled brake applications keep the speed safe without overheating the brakes. Riding the brakes can cause them to fade, and a heavy tanker with surge is very hard to stop if the brakes fail.
