You plan to move into the next lane. Considering the blind spots marked in red in the picture, what should you do?
Correct answer: Use your turn signal, look in your mirrors, and check over your shoulder.
Answer options
AUse your turn signal, look in your mirrors, and check over your shoulder Correct
BUse your turn signal and check over your shoulder, then change lanes
CUse your turn signal and look in your mirrors, then change lanes
Why
The red zones in the picture are areas no mirror shows, so a mirror check alone can miss a car there, while a head check alone can miss traffic closing in fast from behind. Signal, use the mirrors, and then look over your shoulder before moving over.
