What does the term "blind spot" refer to?

The term "blind spot" specifically refers to areas around your vehicle that cannot be observed using mirrors. These areas typically exist on either side of the vehicle and directly behind it, where the mirror does not provide a clear view. Drivers need to be aware of blind spots, especially when changing lanes or merging into traffic, as other vehicles or obstacles may be present in these zones without the driver's knowledge.

Understanding blind spots is crucial for safe driving, as it emphasizes the importance of physically checking over your shoulder or using additional safety measures, like blind spot monitoring systems in some modern vehicles, to ensure that it is safe to maneuver. The concept does not pertain to areas directly in front of the vehicle or to areas that are easily visible, which would not be classified as blind spots at all.
