The correct answer is that you should back so that the fifth wheel slot is in line with the trailer kingpin. This ensures that as you reverse, the connection between the tractor and trailer occurs smoothly and accurately. Aligning the fifth wheel slot with the kingpin is crucial for safe and secure coupling, allowing the locking mechanism to engage properly.

When the fifth wheel is aligned with the kingpin, it minimizes the chance of a misalignment, which could lead to an unsafe connection. Proper alignment is necessary to maintain control and stability while connecting the trailer, ensuring that the load is secure and the vehicle operates safely on the road.

The other options do not provide the necessary alignment needed for safe connection. Aligning with the rear bumper or front bumper does not directly facilitate the coupling process, and aligning with the driver’s side door is not practical for effective backing. The focus should always be on the kingpin for safe trailer coupling.
