When changing lanes on a multi-lane highway, after checking your mirrors, what is the crucial final step to ensure safety before maneuvering?

✓ Correct Answer: Option C

Mirrors have blind spots where other vehicles may not be visible. A head check (looking over your shoulder in the direction you intend to move) is essential to visually confirm that the blind spot is clear before changing lanes, preventing collisions. Accelerating without checking is dangerous. Hazard lights are for emergencies when stopped or driving very slowly. Honking is for warning, not for signaling a lane change.
