Stability always decreases as speed increases and sudden moves will always make the situation worse. Ensure you hold the steering wheel steady and don’t make any sudden turns.
It is a great idea to practice reaching for the trailer brakes when stationery. That way you instinctively know where the control is. You can also get the control fitted so that it is central in the vehicle and your passenger can apply the trailer brakes if your hands are too busy holding the steering wheel steady.
Also ensure that you have your electric brakes set up suitably for your trailer. There are various models available so check your manufacturer’s instructions to work out what is right for you.
Electronic Stability Control
Electronic Stability Control (ESC) is a great safety feature to reduce the chance of caravan sway. The ESC system installed on a caravan uses a sensor underneath the van to monitor sideways movements, small oscillations or sudden jerks. When these forces cause the van to lurch to a critical point, the system applies selective braking to bring the van back into line. Essentially ESC will apply the trailer brakes for you if things start to get a bit hairy and are likely to be able react faster than you as the driver.
Many new caravans come with ESC already installed or it may be an optional extra. If you have an older van, its easy to have a system retrofitted.
It should also be mentioned that as good as ESC systems are, they aren’t infallible and are not a replacement for careful driving. Careful driving is still the most effective tool to combat the dreaded sway and keep you and your family safe on the road. However, in the event that things do get a bit wobbly, it’s nice to know there’s an ESC system doing its bit to help out.
