Driving Safely第 50 / 60 题
If your trailer begins to swing out in a jackknife, what should you generally do?
a.Brake harder to stop the swing
b.Recognize it early by watching your mirrors and release the brakes if it is a braking-induced skid to regain traction
c.Turn the steering wheel sharply toward the skid
d.Accelerate hard to straighten it
解析
If the trailer wheels lock and the trailer starts to swing, you should recognize it early through your mirrors and, if braking caused it, ease off the brakes so the trailer wheels can regain traction and roll straight again. Continuing to brake hard keeps the wheels locked and worsens the skid. Early detection is essential because a full jackknife is hard to correct.
