In the diagram, the red zones beside the car are blind spots. What is the correct way to change lanes?
Correct answer: Signal, check the mirrors, then glance over your shoulder.
Answer options
ASignal, check the mirrors, then glance over your shoulder Correct
BSignal, check the mirrors, then move over without a head check
CSignal, glance over your shoulder, then move over without the mirrors
Why
The signal warns other drivers, the mirrors show traffic behind and to the sides, and a quick glance over your shoulder covers the red blind-spot zones that no mirror reaches. Skipping either check can hide a car that is right beside you.
