What should a driver be responsible for when reversing a vehicle?

A driver is responsible for the overall safety and awareness of the surroundings when reversing a vehicle. This means not only relying on the rearview mirror but also being vigilant about the front and offside areas of the vehicle. The key aspect of this responsibility involves ensuring that the banksman, who assists with guiding the vehicle, is within view. This helps to facilitate safe maneuvering and prevent accidents, as the driver can follow the banksman's directions while also being aware of any obstacles or pedestrians that may be in the path of the vehicle.

Considering the other options, focusing solely on the rearview mirror or the right side of the vehicle does not encompass the full scope of responsibility needed while reversing. Understanding that awareness should include various perspectives around the vehicle reinforces the importance of a comprehensive approach to vehicle safety during reversing maneuvers. The mention of the back seats lacks relevance in the context of reversing, as they are not part of the driver’s immediate environment or concern when monitoring the external surroundings.
