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

The term "blind spot" refers to areas around your vehicle that cannot be seen in mirrors. When driving, blind spots are the regions directly to the sides and sometimes behind your vehicle that are not visible through your rearview and side mirrors. This lack of visibility can make it dangerous when changing lanes or merging, as another vehicle or pedestrian could be located in these blind spots without your awareness. Understanding the concept of blind spots is crucial for safe driving practices, as it emphasizes the need for head checks or shoulder checks to ensure that the surrounding area is clear before making any maneuvers.
