What should you do if the tongue weight of a trailer is too heavy?

When the tongue weight of a trailer is too heavy, it significantly impacts the handling and steering of the towing vehicle. A heavy tongue weight can press down on the rear of the vehicle, causing the front wheels to lift slightly. This results in less steering control, making it difficult for the driver to maneuver the vehicle safely. Steering becomes less responsive, increasing the risk of an accident, especially when making turns or navigating curves.

Increased tongue weight doesn't improve fuel efficiency; in fact, it can hinder the towing vehicle's performance due to the added strain on the engine and suspension. While it is possible for a heavy tongue weight to lead to swaying if mismanaged, the primary concern is the negative impact on steering control, as stated in the correct choice. Recognizing and addressing proper tongue weight is essential for safe towing practices.
