What should you do before moving into another lane on a multilane highway?

Correct answer: D – Signal and check your mirrors and blind spot
Before moving right or left, exercise due care to determine that the movement can be made with reasonable safety and signal appropriately. Check the rearview and side mirrors, then look over your shoulder toward the lane you plan to enter. Identify a safe opening and look again before steering into the lane.
