The drawbar of a full trailer is to be kept level with the coupling height of the approaching towing vehicle. How is this ensured?

You answered correctly. The drawbar of a full trailer must be level with the towing vehicle’s coupling point for safe and stable connection. This is achieved by using the height adjustment system of the trailer. This system allows you to raise or lower the trailer’s drawbar to match the coupling height of the towing vehicle precisely. Using a person to direct or adjusting the towing vehicle’s height is not the standard or reliable method. Always use the trailer’s height adjustment system to ensure a secure and level connection when coupling. This improves safety and prevents excessive wear or uneven loading on the trailer and the towing vehicle.
