What might indicate that you did not secure the trailer properly?

The indication that suggests the trailer is not secured properly is the movement of the trailer. When a trailer is properly secured to the tractor, it should remain stable and not shift from side to side or exhibit any significant movement while driving. If the trailer is moving, it can point to an improper connection to the vehicle or that securing mechanisms, such as safety chains or hitch locks, are not adequately engaged. This movement can lead to dangerous driving conditions and could contribute to accidents, emphasizing the importance of checking for trailer stability before setting off.

Excessive tire wear might indicate other mechanical issues or problems related to loading but doesn't directly relate to trailer security. Unusual noises from the tractor could suggest engine or mechanical problems, unrelated to the trailer being secured. Increased fuel consumption may signal that the load is too heavy, causing strain on the engine, but it doesn't provide a clear indication of whether the trailer is secured properly. In contrast, the clear and direct signal of trailer movement directly correlates with concerns about proper securing to the vehicle.
