The picture shows what your mirrors cover and the blind spots they miss. What should you do before moving into another lane?
Correct answer: Signal, check the mirrors, and glance over your shoulder.
Answer options
AOnly signal and check the mirrors
BSignal, check the mirrors, and glance over your shoulder Correct
COnly signal and glance over your shoulder
Why
As the picture shows, the mirrors leave blind spots on both sides of the car, so a quick look over your shoulder is the reliable way to spot a vehicle hiding there. Signal to announce your move, check the mirrors for traffic behind you, and then do the head check before you move over.
