Adjusting your mirrors can completely remove all blind spots around a vehicle.

• A. True
• B. False
• C. Not sure
• D. It depends on the vehicle

Answer: (B)

False. Mirrors reduce blind spots but cannot eliminate them completely because the vehicle’s shape and the angle of view create areas you can’t see through mirrors alone. Even with perfect adjustment, there are zones directly to the side and just behind the vehicle that remain out of sight. To minimize risk, set the side mirrors so you can just see the edge of your own car in the far outer portion of each mirror, use the center rearview to cover the middle, and always do a quick head check to look into lanes you plan to use before changing lanes or merging. Relying only on mirrors can leave you blind to fast-approaching vehicles in those spots, so shoulder checks are essential.
