By adjusting your mirrors, is it possible to remove all blind spots around a vehicle?

• A. True
• B. Sometimes
• C. Only with convex mirrors
• D. False

Answer: (D)

The key idea is that mirrors extend what you can see, but they cannot eliminate all blind spots. Even with carefully adjusted side and rear-view mirrors, there will still be small areas to the sides and rear that you can’t view without moving your head. Convex mirrors widen the field of view and can help reduce some blind spots, but they distort distance and don’t remove every blind spot either. For safety, you should adjust mirrors to minimize blind spots and then perform a quick shoulder check by turning your head before changing lanes or merging. That’s why the statement is false: you cannot remove all blind spots with mirror adjustments alone.
