The vehicle driver must sign DD Form 626 at which times regarding the vehicle's load?

The correct response indicates that the vehicle driver must sign DD Form 626 both before and after loading, as well as during the inspection of the vehicle’s load. This procedure is in place to ensure that all necessary safety checks are conducted and recorded properly, confirming that the vehicle is prepared for transport according to the required guidelines.

Signing before loading allows the driver to acknowledge that they have reviewed the vehicle's condition and load before the transportation process begins. After loading, the driver's signature reaffirms that they have checked the completed load for compliance with safety and regulatory requirements. The inspection process further ensures that everything is in order and meets the safe transport criteria.

The combined requirement for signatures at these three critical points ensures thorough oversight and accountability throughout the transportation process, ultimately promoting safety and adherence to standards.
