While inspecting a sliding fifth wheel during a combination-vehicle walk-around, why does the driver check that it is not positioned too far forward?

Question

Accepted Answer

Because a fifth wheel too far forward can let the tractor frame hit the landing gear, or let the cab hit the trailer, during turns

Answer

Because a fifth wheel too far forward will prevent the kingpin from ever locking into place

Answer

Because sliding fifth wheel position has no effect on vehicle operation and is only checked for paint damage

Answer

Because it is only a concern on vehicles without antilock brakes
