Driving Safely第 51 / 60 题
Why do combination vehicles need a longer following distance than smaller vehicles?
a.Because trailers have brighter lights
b.Because they use less fuel
c.Because they are heavier and longer, so they take more time and distance to stop
d.Because the trailer has no brakes
解析
Combination vehicles are heavy and long, so they need much more distance and time to stop than cars. A good rule is at least one second of following distance for every 10 feet of vehicle length at low speeds, adding a second above 40 mph. More space gives you time to react and stop safely.
