Before moving into another lane, what must you do?

Correct answer: C – Check mirrors and turn your head to inspect the blind spot
Blind spots near the rear corners of a vehicle may hide another vehicle, motorcycle, or bicyclist. Check the mirrors and turn your head to verify that the area is clear before changing lanes. A vehicle must not leave its lane until the driver has determined that the movement can be made safely.
