Safe Driving第 34 / 120 题
Rain has just begun after a long dry spell and the road surface is slick. How should you adjust your following distance and speed?
a.Add at least one second of following distance and reduce speed by about one third
b.Keep the same following distance but brake earlier
c.Increase speed slightly to get off the wet road sooner
d.Follow closer so the vehicle ahead clears water from your lane
解析
On a wet road you should slow by roughly a third and add space, because traction and stopping ability are both reduced. Braking earlier alone does not create the extra cushion, and increasing speed or following closer directly increases the risk of a rear-end collision.
