What should be done if a vehicle begins to sway while being towed?

When a vehicle begins to sway while being towed, the appropriate response is to steer gently to stabilize the vehicle. This method allows the driver to correct the swaying motion gradually without making abrupt changes that could worsen the instability. Steering gently helps direct the tires back into alignment with the direction of travel and minimizes the risk of losing control.

Accelerating in response to swaying can lead to further instability, as increasing speed might exacerbate the sway rather than remedy it. Braking hard could cause the tow vehicle and trailer to become unbalanced, leading to a potential jackknife situation. Switching gears does not directly address the immediate need for stabilization; it is better to focus on maintaining control through careful steering adjustments. Therefore, steering gently serves as the most effective method to regain stability while towing.
