What check should be made regarding the tailgate of a truck?

The check regarding the tailgate of a truck should focus on its proper operation and the security of its locking mechanism. Ensuring that the tailgate operates correctly is vital for functionality, as it needs to open and close smoothly without obstruction. A secure locking mechanism is equally important, as it helps prevent cargo from falling out while the vehicle is in motion, thereby enhancing safety for both the driver and other road users.

While other checks, such as towing capacity or aesthetic considerations like matching paint, can be relevant in specific contexts, they do not address the primary functional and safety aspects of the tailgate that are critical during a pre-trip inspection. Focusing on the operational integrity and security of the tailgate directly impacts vehicle safety and load security during transit.
