What should you do to shift asphalt in a truck when you cannot reach it?

Locking the tailgate and lifting the box is the most effective method for shifting asphalt in a truck when access is limited. This technique allows the material to slide toward the rear of the truck more easily, as the upward movement of the bed can create an angle that encourages the asphalt to flow out. By securing the tailgate, you prevent the material from spilling out prematurely, enabling a controlled unloading process.

This method avoids the potential issues associated with the other options. Unloading from the side may not be safe or practical, as it can lead to uneven distribution or spillage. Pounding on the box, while it may seem like a way to dislodge the material, can cause damage to the truck and might not be effective in moving large volumes of asphalt. Driving in reverse could be dangerous and ineffective, as it may not promote the movement of the material in a controlled manner.
