Safe DrivingCâu 50 / 120
You are about to change lanes on a busy interstate. What is the correct communicating procedure?
a.Signal early, check mirrors and the blind spot, change lanes gradually, and cancel the signal after completing the move
b.Change lanes first and signal once you are established
c.Flash your headlights instead of signaling
d.Signal only if another vehicle is close behind
Giải thích
Signaling early gives other drivers time to react, and cancelling afterward prevents confusion about your intentions. Signaling after the move, substituting headlight flashes, or signaling only sometimes leaves other drivers guessing.
