Why should you check that the tractor frame clears the trailer's landing gear as you pull away after uncoupling?

Pick an answer

1. Landing gear clearance is never a real concern once the trailer has already been uncoupled from the tractor
2. It only matters for trailers with automatic landing gear
3. It is checked only during the initial coupling, not when leaving
4. Pulling out too sharply or too soon can cause the tractor to strike the landing gear or trailer nose
