This diagram shows the zones your mirrors cover and the blind spots they miss. What is the right routine for changing lanes?
Correct answer: Signal, check your mirrors, and glance over your shoulder.
Answer options
ASignal, check your mirrors, and glance over your shoulder Correct
BSignal, check your mirrors, and then move over
CSignal, glance over your shoulder, and then move over
Why
Your turn signal warns other drivers, your mirrors show traffic behind and beside you, and a quick look over your shoulder covers the blind spots the mirrors cannot reach. Skipping either check can leave a vehicle right beside you unnoticed, and skipping the signal leaves other drivers unaware that you are moving over.
