When backing up a large truck, what should you do?

Having someone guide you while backing up a large truck is the best practice for several reasons. The size and blind spots of large trucks can obscure the driver's view of their surroundings, making it difficult to see obstacles or pedestrians. A guide can provide a clear view of what is behind and around the truck, helping to prevent accidents and ensuring safety.

Moreover, relying solely on mirrors or backup cameras can lead to misjudgments, as these tools are not foolproof. Mirrors may not capture all angles, while backup cameras can have limited visibility or can be obstructed. Having a human guide helps mitigate these risks, allowing for more precise maneuvers and better communication about when it is safe to proceed.

Backing up quickly, as suggested in one of the other options, is not advisable because it increases the risk of accidents. Taking time to back up carefully under the watchful guidance of someone knowledgeable about the area ensures a safer and more controlled operation.
