Which statement about mirror adjustment is true?

• A. Mirrors are optional
• B. Mirrors should be ignored when seat adjusted
• C. Proper adjustment reduces blind spots
• D. Only the left mirror matters

Answer: (C)

Properly adjusting mirrors expands what you can see and directly reduces blind spots, which is a key part of safe driving. When the side and rearview mirrors are set correctly, you gain better visibility of vehicles in adjacent lanes and objects near your car as they move into or out of your path. This makes lane changes and merges safer because you’re less likely to be surprised by vehicles that would otherwise be hidden. Mirrors are not optional tools; your seating position also matters, since how you sit affects what the mirrors show you. If you ignore mirror adjustment while setting your seat, you may end up with gaps in coverage where hazards can hide. And relying on only one mirror leaves large blind areas—coverage from both side mirrors plus the rearview mirror gives you the full picture you need to monitor traffic on all sides. So the statement that proper adjustment reduces blind spots captures the essential safety benefit of using mirrors correctly.
