The picture marks the blind spots that mirrors do not cover. Which routine is correct for changing lanes?
Correct answer: Signal, check your mirrors, then do a shoulder check.
Answer options
ASignal, check your mirrors, then do a shoulder check Correct
BSignal, check your mirrors, then move over
CSignal, do a shoulder check, then move over
Why
Mirrors leave a blind spot on each side of the car, like the red areas in the picture, so after signaling and checking the mirrors you still need to turn your head and look before moving over.
