Rain can create a number of hazards on the road depending on how hard it falls. A light sprinkle can cause oils to leach from the road, resulting in a slippery surface that can affect the traction on a caravan or towing vehicle. Slow down and keep a speed-appropriate distance between you and the vehicle in front.
Heavy rainfall will quickly limit visibility of other vehicles and the road ahead. If you can’t see very far or lose sight of the caravan in your mirrors, pull over at the first available rest stop until it eases.
Heavy rain can cause water to cover the road resulting in aquaplaning, or complete loss of traction. If you approach water covering the road, reduce your speed, steer carefully and brake lightly (remember to account for the increased braking distances).
If it hails, you will compound the impact of the hail if you keep driving. Find some shelter until it passes. If you cannot get under cover, park facing the storm. Your windscreen is usually made of toughened glass and so this will reduce the area of exposed caravan windows.
Here are some tips for wet weather travelling:
There’s no sense taking risks when driving in rain, as the dangers are always greater. If the weather sets in, it might be best if you do the same and wait it out somewhere safe.
