As the picture shows, mirrors leave some areas uncovered. What should you do before you move from one lane into another?
Correct answer: Use the turn signal, scan the mirrors, and look back over your shoulder.
Answer options
AUse the turn signal, scan the mirrors, and look back over your shoulder Correct
BUse the turn signal and scan the mirrors, then move over without turning your head
CUse the turn signal and look back over your shoulder, without scanning the mirrors
Why
The turn signal warns other drivers, the mirrors show vehicles to the rear and sides, and turning your head reveals the blind spots marked in red. Skipping the mirror check or the head check can put you in the path of a vehicle you never saw.
