Locked trailer wheels can make a trailer slide out and swing to the side. Under which load condition is this most likely?

Correct answer: When the trailer is empty or carries a light load.

Answer options

  1. AWhen the trailer is empty or carries a light load Correct
  2. BWhen the trailer is loaded to its full legal weight
  3. CWhen the trailer carries more weight than it is rated for

Why

An empty or lightly loaded trailer has little weight pressing its tires onto the road, so it has poor traction. Its wheels lock up more easily, and the trailer can slide sideways and swing out of line.
