Which type of coupling procedure is required for a double/triple setup?

Answer: C — two-step coupling process for safety

In a double/triple setup, a two-step coupling process is crucial for ensuring safety and stability during transportation. This method typically involves first securing the converter dollies to the rear of the lead trailer and then properly connecting the subsequent trailers. This two-step process allows for thorough checks of attachment points, ensuring that each trailer is securely coupled before moving. By implementing this additional safety measure, the risk of uncoupling or swaying is significantly minimized during transit, which can be more critical given the complexity and length of double and triple trailer combinations. This approach not only enhances the safety of the vehicle setup but also promotes better handling and control while driving. The intricacies involved in managing multiple trailers necessitate a more careful coupling procedure than what might be applied to simpler setups, underscoring the importance of the two-step coupling process.
