By If you’ve ever towed a trailer and felt it start to fishtail behind you, you know just how scary trailer sway can be. It’s not only nerve-wracking—it can be dangerous. Whether you’re hauling a car hauler, utility trailer, enclosed trailer, or a dump trailer, understanding trailer sway is key to keeping your towing experience safe and smooth.
Let’s break it down:
What Is Trailer Sway?
Trailer sway happens when your trailer starts to move side-to-side uncontrollably, usually at higher speeds. It can be caused by things like:
- High winds or wind gusts from passing vehicles
- Improper weight distribution
- Driving too fast for conditions
- Tire pressure issues
- Suspension or hitch problems
When sway kicks in, it can feel like the trailer is trying to take control of the tow vehicle—and if not handled properly, it can lead to serious accidents.
What To Do If Trailer Sway Happens
If your trailer starts to sway while you’re driving, stay calm and follow these steps:
- Don’t slam on the brakes. Sudden braking can make the sway worse.
- Gradually ease off the gas. Let your vehicle slow down naturally.
- Hold the steering wheel steady. Avoid jerky corrections—stay centered in your lane.
- Use trailer brakes if you have them. If your trailer has its own brake controller, applying just the trailer brakes can help stabilize it.
- Wait for it to settle. Once the sway stops, pull over when safe to inspect your load and setup.
How To Prevent Trailer Sway
The best way to handle trailer sway is to stop it before it starts. Here’s how:
Load It Right
- Make sure 60% of the trailer’s weight is in the front half of the trailer, ahead of the axle.
- Keep the load balanced side-to-side.
- Secure everything so nothing shifts while towing.
Check Your Hitch
- Use a weight distribution hitch if needed, especially for heavier loads.
- Consider adding sway control devices—they’re worth it.
- Double check your coupler and safety chains every time you tow.
Check Tire Pressure and Suspension
- Make sure all tires (tow vehicle and trailer) are properly inflated.
- Look for worn suspension components or uneven tire wear.
Mind Your Speed
- Trailer sway gets worse the faster you go. Stick to safe towing speeds—even if the speed limit is higher.
- Slow down when it’s windy or you’re passing large trucks.
Know Your Limits
- Don’t exceed your vehicle’s towing capacity.
- Make sure your trailer’s load doesn’t go over its weight rating.
Final Thoughts
Trailer sway can happen to anyone, but with the right setup and a bit of know-how, it’s totally avoidable. Always give your trailer setup a once-over before hitting the road, and when in doubt, take it slow.
