What are "blind spots" in driving?

Blind spots refer to areas around a vehicle that cannot be seen by the driver through the mirrors. These areas present a significant challenge for drivers because they can conceal other vehicles, cyclists, or pedestrians, making it difficult to make safe lane changes or turns.

Understanding the concept of blind spots is critical for safe driving, as it emphasizes the importance of making head checks and using a full awareness of the vehicle's surroundings rather than solely relying on mirrors. This knowledge aids in preventing collisions and enhances overall road safety.

The other options do not relate directly to the definition of blind spots. While visible areas, poor lighting conditions, and high-accident zones are all important aspects of driving safety, they do not capture the specific nature of blind spots as areas that are unseen by the driver.
