What is the definition of a blind spot?

• A. Area not visible through mirrors due to lighting
• B. Area visible to the side only
• C. Area not visible through mirrors or direct observation
• D. Area behind the vehicle that can be seen in a rear window

Answer: (C)

A blind spot is the area around your vehicle that you cannot see either in your mirrors or by looking directly over your shoulder. It exists because the car’s shape and the way mirrors are angled leave zones to the sides and rear that aren’t visible without turning your head or adjusting the mirrors. Because of this, another vehicle can be there and you wouldn’t notice unless you check. To stay safe, adjust mirrors properly to maximize visibility, and always perform a quick shoulder check before changing lanes or merging. Relying on the rear window alone won’t reveal these unseen areas.
