As the red zones in the picture show, your mirrors do not cover everything beside you. Which set of steps should you use to change lanes?
Correct answer: Turn on your signal, check the mirrors, then look over your shoulder.
Answer options
ATurn on your signal and check the mirrors, then move over
BTurn on your signal and look over your shoulder, then move over
CTurn on your signal, check the mirrors, then look over your shoulder Correct
Why
Signaling tells other drivers what you plan to do, and the mirrors show vehicles to the rear and sides. The red zones are blind spots the mirrors miss, so a quick head check over your shoulder is needed to confirm the lane is open before you steer into it.
