When backing up a commercial vehicle, what should drivers do?

When backing up a commercial vehicle, it is essential for drivers to look behind them and use a guide if possible. This practice enhances situational awareness and safety, as it allows the driver to have a clear view of the area behind the vehicle, which can often be blind to mirrors alone. By physically turning to check their surroundings and relying on a guide, whether that be another person who can assist in providing directions or visual cues, the driver can better avoid obstacles, pedestrians, and other vehicles.

Using mirrors to back up is helpful, but it does not provide a full perspective of the area behind the vehicle. Mirrors can only show a limited view and may miss lower objects or hazards. Sounding the horn continuously could be distracting and does not substitute for visual checks. Turning quickly to save time can potentially lead to accidents or collisions, as it hinders the driver's ability to fully assess their surroundings. Therefore, actively looking back and utilizing a guide when necessary is the most effective and safe strategy for backing up a commercial vehicle.
