What is the primary purpose of adjusting your outside mirrors?

• A. To improve fuel efficiency
• B. To increase braking distance
• C. To reduce blind spots
• D. To enhance rear visibility

Answer: (C)

Outside mirrors are angled to give you a broad view of the lanes beside and behind your vehicle, so you can spot cars that might be in your blind spots. Reducing those blind spots is what makes lane changes and merges safer, since you can see approaching vehicles earlier and react in time. A practical setup is to adjust the mirrors so you can just see the edge of your own car in the inner part of each mirror and the adjacent lane in the outer portion. This helps you cover areas your rearview mirror can’t reach, without relying on a quick shoulder check every time. It’s not about fuel efficiency or braking distance, and while mirrors do show some rear area, the main purpose is to minimize blind spots for safer highway and city driving.
