Safe Driving第 41 / 120 题
You are driving at night on an unlit two-lane road. Why should you keep your speed low enough to stop within the distance your headlights illuminate?
a.Because high beams are illegal on two-lane roads
b.Because engine braking works poorly at night
c.Because tire traction is always lower at night
d.Because if you cannot stop within the lighted distance you are overdriving your headlights and cannot react to a hazard in time
解析
Low beams light roughly 250 feet and high beams roughly 350 to 500 feet, so speed must be low enough to stop inside that distance. High beams are legal when no oncoming traffic is present, engine braking works the same at night, and traction depends on the surface rather than the hour.
