Why is it important to check blind spots when backing up a commercial vehicle?

It is crucial to check blind spots when backing up a commercial vehicle to ensure that there are no obstacles or pedestrians in the way. Blind spots are areas around the vehicle that cannot be seen through mirrors, and they can conceal hazards that pose a significant risk during maneuvers like reversing. By checking these areas, the driver can avoid accidents, preventing harm to people and damage to property. This practice is a fundamental aspect of safe driving and is particularly important in commercial driving, where larger vehicles may have larger blind spots compared to regular passenger vehicles. The act of being vigilant about blind spots contributes to overall road safety and effective vehicle operation.
