Is it true that you should look into the back of the fifth wheel to check if it is locked into the kingpin?

Looking into the back of the fifth wheel to check if it is locked onto the kingpin is an important safety practice for commercial drivers. The fifth wheel mechanism connects the tractor to the trailer, and ensuring that it is properly secured is crucial for safe operation.

When approaching the fifth wheel, a driver should visually confirm that the locking mechanism is engaged. This prevents any accidental separation of the tractor from the trailer while the vehicle is in motion, which can lead to serious accidents and injuries.

This practice should be a standard step in the pre-trip inspection process every time a driver couples a trailer, not just for new drivers or on occasion. A visual inspection ensures the driver is aware of the secure connection, reinforcing safety on the road. Proper training emphasizes the importance of these checks, making them a necessary part of routine vehicle operation.
