Blind spots can be reduced but not eliminated.

• A. Completely eliminated
• B. Can be eliminated with advanced mirrors
• C. Reduced but not eliminated
• D. They disappear at dawn

Answer: (C)

Blind spots are the areas around your vehicle that you can’t see in your mirrors. Even with the best mirror setups, you can’t remove every angle you can’t observe, so blind spots can be reduced but not eliminated. You reduce them by properly adjusting your side mirrors and seat position, using the rearview mirror in combination with occasional quick head checks, and making sure you don’t rely solely on mirrors when changing lanes. Since there will always be some space you can’t see, the safe habit is to check over your shoulder before merging or changing lanes and treat blind spots as present at all times. Dawn or daylight doesn’t change this fact.
