As the picture shows, mirrors do not cover every area around your car. How should you change lanes?
Correct answer: Signal, look in the mirrors, and then turn your head.
Answer options
ASignal and look in the mirrors, but skip turning your head
BSignal, look in the mirrors, and then turn your head Correct
CSignal and turn your head, but skip looking in the mirrors
Why
Mirrors show the green areas in the picture but not the red blind spots, so a signal and a mirror check are not enough by themselves; you also need a quick head check before you move over. Change lanes only when the gap is clear.
