According to motor vehicle experts, trailer sway is the leading cause of accidents involving towed trailers. While there are no known statistics to back up this claim, any motorist can tell that a trailer swaying violently while in transit is a mishap waiting to happen.

You can’t eliminate trailer sway as it is the inevitable effect of forces acting on the trailer and the towing vehicle. A heavy trailer will tend to sway more than a lighter trailer as it will magnify the impact of wind on the trailer’s side. A 30-mph wind is estimated to exert 2.3 psf. The faster the wind and the heavier the trailer, the more likely it will be for the trailer to sway uncontrollably.

However, you can reduce the swaying with the right trailer hitch, which distributes the load between the towing vehicle’s rear axle and trailer’s front axle. A stable hitch can counter the natural forces pushing the trailer sideways, and thus prevent accidents.

Along with this, it will also help to redistribute the trailer’s load, by placing heavier items ahead of the trailer axle. If the trailer has a brake, this can be used control the swaying. It is also important to drive at a safe speed, and to be aware of any movement your trailer makes while in motion.
