In what position should the fifth wheel be during inspection?

During the pre-trip inspection of a truck equipped with a fifth wheel, it is essential that the fifth wheel is properly greased and locked in place. This ensures that the connection between the tractor and the trailer is secure and safe for travel. A properly locked fifth wheel prevents any movement between the truck and trailer during operation, which is crucial for maintaining control of the vehicle and for the safety of all road users.

Additionally, having the fifth wheel properly greased ensures smooth operation and reduces wear over time, which can prolong the life of the component. Regular maintenance checks, including greasing, help to prevent issues that could lead to dangerous situations on the road.

The other options present scenarios that could adversely affect safety. A loose fifth wheel would lead to instability, while removing it from the vehicle or positioning it in an elevated state does not meet the necessary conditions for safe vehicle operation.
