What is a "blind spot" while driving?

A "blind spot" refers to an area around a vehicle that cannot be seen by the driver through the mirrors. These spots can pose significant safety risks because drivers may not be aware of other vehicles, pedestrians, or obstacles in these areas. Understanding where your vehicle's blind spots are is crucial for safe driving, as it encourages drivers to turn their heads and check their surroundings before changing lanes or merging.

The other areas mentioned in the options, such as areas visible in mirrors or those immediately in front or behind the vehicle, involve sections that can typically be observed by the driver. Recognizing what constitutes a blind spot helps drivers take necessary precautions, such as shoulder checks, to avoid accidents.
