When checking if a trailer is securely coupled, what position should the landing gears be in?

When checking if a trailer is securely coupled, the landing gears should be positioned slightly raised. This position indicates that the weight of the trailer is being supported by the tractor's fifth wheel rather than the landing gear. If the landing gear is completely raised, it might not be properly supporting the trailer, which could lead to instability during driving. Additionally, having the landing gear firmly on the ground or completely lowered would suggest that the trailer is not fully attached to the tractor, which might indicate a risk of separation while on the road. Therefore, slightly raising the landing gear is an ideal position to confirm that the trailer is securely coupled while still ensuring it's ready to be moved.
