What is the purpose of performing a blind spot check?

• A. To verify fuel level
• B. To evaluate weather conditions
• C. To check tire pressure
• D. To ensure there are no vehicles in areas not visible in mirrors before changing lanes

Answer: (D)

Blind spots are areas beside and behind your vehicle that mirrors can’t show. A blind spot check means turning your head to scan those areas before changing lanes or merging. This helps you confirm there isn’t a vehicle in a lane you’re about to enter, reducing the risk of a sideswipe or collision. Relying only on mirrors can miss cars in those zones, especially with big trucks or in heavy traffic.

The other options aren’t related to visibility in adjacent lanes: fuel level, weather conditions, or tire pressure are separate vehicle checks that don’t address whether another vehicle is in your blind spot.
