Which statement is true regarding the distance between the dolly and the nose of the trailer when coupling?

The statement that the dolly can be close to the nose of the trailer is correct because when coupling a tractor to a trailer, the dolly plays a critical role in aligning the trailers properly during the coupling process. Keeping the dolly near the nose of the trailer allows for a smoother connection between the two units, ensuring that the mechanisms properly engage.

In practice, maintaining the correct position of the dolly relative to the trailer helps reduce the risk of misalignment that could cause difficulties when coupling. It is essential for the driver to ensure that the dolly does not create a large gap that could necessitate additional adjustments during the coupling process. By keeping the dolly close to the trailer's nose, the driver facilitates a safer and more efficient connection.

Other statements regarding the distance imply unnecessary gaps or suggest positions that could complicate the coupling, leading to safety concerns or operational inefficiencies. Understanding the correct positioning is vital for anyone operating doubles or triples, as proper coupling techniques are fundamental to safe driving.
