Using the picture of mirror coverage and blind spots as a guide, what is the proper way to change lanes?

Answer options
ASignal and check your mirrors, with no need to glance back
BSignal and glance over your shoulder, with no need for mirrors
CSignal, check your mirrors, and glance over your shoulder Correct

The red areas in the picture are blind spots that neither the side mirrors nor the rearview mirror can show. After signaling and checking the mirrors, a quick look over your shoulder toward the lane you want is the only way to spot a vehicle hiding there.
