What should you check about the fifth wheel plate before backing under a trailer?

a.That it is painted the correct color
b.That it is properly greased to prevent steering problems and reduce friction
c.That it is completely dry
d.That the jaws are already closed

Explicación

The fifth wheel plate should be properly lubricated with grease to reduce friction between the trailer and tractor. A dry fifth wheel can cause steering problems and hard, jerky turning. You should also confirm the jaws are open and the fifth wheel is tilted down before backing under.
