When backing up a truck, what is the best practice to ensure safety?

Getting out and checking the area behind the vehicle first is crucial for ensuring safety while backing up a truck. This practice allows the driver to visually assess the surroundings for any obstacles, pedestrians, or other vehicles that might be hidden from the mirrors. Mirror use can be helpful, but they may not provide a complete view of the environment, especially in larger trucks where blind spots can exist. By stepping outside and conducting a thorough visual inspection, drivers can identify potential hazards and make informed decisions before beginning to reverse, ultimately reducing the risk of accidents.

Relying solely on mirrors can lead to blind spots being overlooked, and using the horn frequently offers no assurance of safety, as it does not eliminate the need to check behind the vehicle. Continuously reversing until sightlines become clear can create dangers, as it may lead to collisions with unseen obstacles. Hence, the practice of exiting the vehicle to inspect the area before backing up is the most effective and safest approach.
