Safe Driving第 38 / 120 题
How far ahead should a commercial driver normally be looking while driving?
a.Just past the front bumper
b.About 5 seconds ahead
c.As far as the headlights reach at all times
d.About 12 to 15 seconds ahead, which is roughly a quarter mile at highway speed
解析
Looking 12 to 15 seconds ahead gives you time to see and respond to developing hazards instead of reacting at the last moment. Looking just past the bumper or only 5 seconds ahead is far too short, and headlight range is a night-driving limit rather than a general rule.
