B) The parking lock is off and you may drive away
C) The coupling is not right and should be fixed before diving the coupled unit

Answer 1

When the fifth wheel locking lever is not locked after the jaws close around the kingpin, it means that the coupling is not right and should be fixed before driving the coupled unit.

Step-by-step explanation:

When the fifth wheel locking lever is not locked after the jaws close around the kingpin, it means that the coupling is not right and should be fixed before driving the coupled unit.

In fifth wheel coupling, the locking lever is responsible for securing the jaws around the kingpin, which connects the tractor and trailer. If the lever is not locked, it indicates that the coupling is not properly engaged and could result in the trailer not swiveling on the fifth wheel or the parking lock being off.
