How should air and electrical lines from the tractor to the trailer be managed?

Managing air and electrical lines between the tractor and the trailer is crucial for ensuring safe and effective operation of combination vehicles. The correct approach involves securing the lines while allowing for enough slack or loops to enable turning and articulation of the vehicle. This flexibility is essential because, during turns, the lines need to move with the vehicle without being pulled taut, which could lead to damage or disconnection.

By ensuring the lines are secured but have enough slack, you minimize the risk of them getting snagged or caught, which could lead to failures of essential systems such as the air brakes or electrical connections. Proper management of these lines is vital for maintaining functionality and safety when maneuvering in various driving conditions and during turns.
