How does the stabiliser bar on a caravan work?

The stabiliser bar on a caravan enhances towing stability by reducing sway during travel. It employs friction or a mechanical system to create resistance against lateral movement, effectively dampening any oscillations caused by wind or uneven road surfaces. When the caravan begins to sway, the stabiliser bar engages, providing a counteracting force that helps keep the caravan aligned with the towing vehicle. This results in a smoother and safer towing experience.
