What is a common danger associated with backing a commercial vehicle?

Parked cars
Blind spots
Visibility issues
Being difficult to maneuver

The correct answer is: Visibility issues

While visibility issues are indeed a concern when backing a commercial vehicle, the most critical danger associated with this action is the presence of blind spots. Commercial vehicles typically have larger blind spots compared to regular passenger vehicles, making it harder for drivers to see obstacles or pedestrians who may be behind them. Blind spots are areas around the vehicle that cannot be seen in the mirrors, posing significant risks during maneuvers like reversing. Because of their size and design, large trucks have limited visibility to the sides, back, and corners. This can lead to accidents if the driver is not aware of what is directly behind or to the side of the vehicle. Maneuverability is certainly impacted by the size and configuration of commercial vehicles, and parked cars can also create obstacles, but they fall secondary to the critical risk posed by blind spots. It is essential for drivers of commercial vehicles to perform thorough checks and use mirrors effectively to compensate for these blind spots when backing up.
