What is the last step after connecting to a trailer?

After connecting to a trailer, conducting a pre-trip inspection is crucial because it ensures that all components of the trailer are in proper working condition before hitting the road. This inspection includes checking the brakes, lights, tires, and overall structural integrity of the trailer. Ensuring that the trailer is roadworthy significantly contributes to safety for both the driver and others on the road.

This step is vital because it also helps to identify any potential issues that could lead to accidents or breakdowns during transit. By performing a pre-trip inspection as the last step after coupling, the driver confirms that everything is configured correctly and ready for safe operation.
