Which of the following is a responsibility of a driver regarding cargo transportation?

Ensuring that the cargo is securely tied down and covered is a critical responsibility of the driver in the transportation of goods. Properly securing cargo helps to prevent it from shifting during transit, which could lead to accidents or damage to both the cargo and the vehicle. Additionally, covering the cargo may be necessary to protect it from environmental elements like rain, wind, or debris, and to comply with legal requirements regarding load security.

Securing cargo not only promotes safety on the road but also satisfies legal obligations set forth by the Department of Transportation (DOT) and other regulatory agencies. Drivers must be aware of the correct methods and equipment for securing different types of loads to maintain safety standards and ensure compliance during inspections.

While complying with speed limits, focusing on the vehicle's exterior, and reviewing maintenance records are all important aspects of driving and vehicle operation, they do not directly relate to the specific responsibility of cargo transportation, which is the focus of this question.
