What is the potential consequence of driving a trailer with its landing gear improperly set?

Driving a trailer with its landing gear improperly set can indeed result in the trailer tipping over, especially during sudden maneuvers. The landing gear is designed to provide stability and support when the trailer is parked or stationary. If the landing gear is not correctly adjusted or set, the center of gravity of the trailer might be compromised. This can lead to a higher risk of the trailer overturning if sharp turns or rapid changes in speed are made while driving. This risk is exacerbated with a heavy load, where the weight distribution becomes crucial for maintaining balance on the road.

While the other potential consequences listed may seem plausible, they do not capture the immediate danger posed by an improperly set landing gear as effectively as the risk of tipping over during unexpected maneuvers. Properly setting the landing gear is essential for ensuring safety while driving with a trailer, as it directly influences the operational stability of the vehicle.
