Why is checking blind spots crucial while driving?

Checking blind spots is crucial while driving primarily because these areas may contain vehicles or pedestrians that are not visible in standard mirrors. Mirrors provide a limited field of view, and blind spots are the zones where objects can be hidden from view. If drivers fail to check these areas, they risk missing the presence of other road users, which can lead to collisions during maneuvers like lane changes or turns.

Blind spots exist in several locations around a vehicle, particularly on the sides and rear. For example, when changing lanes, relying solely on mirrors can create dangerous situations if a vehicle is located in one of these blind spots. By turning your head and using peripheral vision to check these areas, drivers can gain a fuller understanding of their surroundings, contributing to safer driving practices and reducing the likelihood of accidents.

While the other choices touch upon various aspects of driving—such as judging speed, ensuring proper mirror use, and legal requirements—they do not capture the primary safety concern of blind spots, which is the risk of unseen vehicles or pedestrians that could lead to a dangerous situation on the road.
