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

When a towed vehicle begins to sway, the proper action is to gently steer into the sway. This technique involves turning the steering wheel in the direction that the vehicle is swaying. By doing so, you help to regain control and realign the vehicle with the direction of travel. This is essential for stabilizing the trailer and preventing further swaying or potential jackknifing.

Increasing speed drastically would likely exacerbate the swaying and increase the risk of losing control. Braking harshly can cause the trailer to skid or become more unstable. Quickly switching lanes could lead to a loss of control or an accident, as you may not have enough space or time to safely maneuver the vehicle. Gentle steering into the sway is a proactive approach to correct the motion and ensure safe towing.
