This diagram shows how far each mirror can see and where the blind spots lie. Which sequence prepares you properly for a lane change?
Correct answer: Turn on the signal, scan the mirrors, and turn your head to check the blind spot.
Answer options
AScan the mirrors, move into the new lane, and then turn on the signal
BTurn on the signal, scan the mirrors, and move over without turning your head
CTurn on the signal, scan the mirrors, and turn your head to check the blind spot Correct
Why
The signal tells others what you plan, the mirrors show what is behind and beside you, and turning your head reveals the blind spots shaded red in the diagram. Signaling only after you have moved over gives other drivers no warning.
