What does the term "blind spot" refer to in driving?

The term "blind spot" refers specifically to areas around a vehicle that are not visible in the rearview or side mirrors. When driving, certain zones, particularly directly behind and to the sides of the vehicle, can be obstructed from a driver's view by the vehicle's body. This can create dangerous situations, as other vehicles, cyclists, or pedestrians may occupy these areas without the driver's knowledge. It emphasizes the importance of checking these blind spots by turning one's head or utilizing technology such as blind spot monitoring systems to ensure safe maneuvering, such as changing lanes or merging. Understanding the concept of blind spots is crucial for safe driving practices, as failing to recognize them can lead to accidents.
