Before changing lanes, how should you check for a blind spot?

• A. Physically turn to check areas not visible in mirrors.
• B. Rely on your side mirrors only.
• C. Ignore blind spots and hope other drivers yield.
• D. Sound the horn, then change lanes.

Answer: (A)

Checking blind spots means looking where your mirrors don’t show. Before you move to another lane, quickly turn your head and look over the shoulder into the lane you intend to enter. This shoulder check reveals vehicles or hazards hidden in the blind spot that mirrors can miss, including fast-approaching cars, motorcycles, or bicycles. Relying only on side mirrors can miss these vehicles, which is why a visual check is essential. Avoiding blind spots or honking won’t substitute for this look. Once you’ve confirmed the lane is clear, signal and merge safely.
