Approximately how many blind-spot incidents occur in the United States each year?

• A. 840,000
• B. 400,000
• C. 1,200,000
• D. 100,000

Answer: (A)

Blind spots are areas beside and behind your vehicle that you can’t see in your mirrors, so changing lanes without checking those zones can lead to crashes or near-misses. The best estimate for how often these blind-spot incidents happen in the United States each year is about 840,000. This figure comes from safety data that tracks lane-change crashes and near-misses attributed to not seeing a vehicle in the blind spot, highlighting how common and serious even routine lane changes can be. This matters for driving practice: always do a shoulder check in addition to using your mirrors, and adjust your mirrors so you can see as much of the side and rear as possible. Signal early, glance over your shoulder before moving, and maintain a safe following distance to give yourself time to react if something enters the blind spot.
