Green zones in the picture show what your mirrors can see, and red zones show your blind spots. What steps make up a safe lane change?
Correct answer: Turn on your signal, check your mirrors, and look over your shoulder.
Answer options
ATurn on your signal and look over your shoulder, then move over
BTurn on your signal and check your mirrors, then move over
CTurn on your signal, check your mirrors, and look over your shoulder Correct
Why
As the red zones show, the mirrors leave a blind spot on each side that only a turn of the head can cover. A safe lane change therefore needs all three steps: signal your intent, check the mirrors for traffic behind and beside you, and look over your shoulder before you steer over.
