If your caravan begins to sway or snake, remain calm and avoid the urge to apply the towing vehicle’s brakes.
Don’t try to steer out of the swaying / snaking. Alternatively hold the vehicle steady and try to stay in the lane. Gently apply the caravan’s electric brakes using the manual control in the tow vehicle. Otherwise, where conditions permit, continue at a steady speed or accelerate slightly until the sway stops.
When a condition of sway has been corrected, slow down and pull off the road safely. Check that your load is correctly distributed within the trailer, making sure that heavier items are placed over the axles of the caravan. A caravan that doesn’t have the load distributed correctly may not handle well and may be the cause of swaying / snaking.
