The roads become a different place when heavy rain and floodwater descend. Driving your motorhome may feel quite daunting, and the conditions can catch out those who are less experienced in driving during adverse weather. With that in mind, we’ve written a handy guide to driving in floods which will help to prepare you for essential journeys.
Avoid driving where possible
The consequences of driving through flood water can be severe. So, ask yourself, do I really need to make this journey? If your trip can be avoided, consider delaying it until the road conditions have improved.
How deep is the water?
If your journey is essential, be sure to exercise caution. If you come across flood water and do not know how deep it is, don’t drive through it. Even if you have a tall motorhome or campervan, your engine could still suck up water through the air intake and damage itself. There are usually alternative routes you can take in these circumstances.
Put your lights on
When visibility is reduced, always turn your headlights on. If conditions are murky, turn your fog lights on when necessary, but make sure to switch them off when the weather improves.
Slow down
Drive no faster than 3-4 miles an hour on flooded routes. Going too fast can mean your motorhome or campervan loses contact with the road. You could also create a wave that splashes other cars, impairing the vision of their drivers.
Use a low gear
To keep the engine revving in a manual vehicle, press the clutch slightly whilst also pressing the accelerator. In an automatic vehicle, use the lowest gear and keep your foot on the accelerator.
Keep moving forward
If you must drive through floods, drive slowly, use a low gear, and do your best to keep engine revs at a high rate. Moving forward continuously helps to avoid stalling the engine.
Brake gently
Once you’ve driven through the water, apply your brakes carefully for at least three seconds. This helps to clear water from your brake pads and discs. You may need to test your brakes a couple of times to make sure they’re working properly.
Maintain visibility
Heavy rain can reduce visibility considerably. Make sure your windscreen wipers are operating effectively, and your demisters are set correctly before you start your journey. Think about leaving your air conditioning on too, as it’ll help stop your windows from misting up. You should also consider using dipped headlights.
Keep a safe distance from other vehicles
Stopping distances increase dramatically in wet conditions, especially for larger vehicles. Ease off the accelerator and leave at least twice as much space between you and the vehicle in front as you would normally.
Keep an eye on other drivers
Road users around you may not be quite so prepared. They may also have visibility issues, so make allowances for others when driving in heavy rain or spray.
Be wary of maintenance hole covers
Water levels change quickly in flood conditions. This means maintenance hole covers can be lifted out of place and moved along in fast flowing water. Open maintenance holes are extremely dangerous. So, keep your eyes peeled and report any you see to the local council as soon as it’s safe to do so.
Always assume that flood water is contaminated
Flood water in towns and cities can carry harmful bacteria from sewers and drains that could cause illness. Agricultural chemicals and animal waste are likely to be found in rural flood water. With that in mind, avoid entering the water if possible.
Be prepared
If you break down in floodwater, stay in the vehicle – your camper is less likely to be swept away than you are. Turn on your hazard lights and contact the emergency services if you are in danger. Once you have addressed your immediate safety, get in touch with your breakdown provider.
Maintain your vehicle
Flash flooding can create issues very quickly. It’s always best to make sure your motorhome is prepared ahead of time. When changing tyres, choose ‘C’ or ‘CP’ marked varieties as they’re made to withstand the weight and pressure of a leisure vehicle. ‘CP’ marked tyres are generally used on motorhomes, whilst ‘C’ tyres suit van conversions. Any mud guards and mudflaps should also be inspected regularly.
You should also:
- Check that your tyres are above the recommended legal tread depth
- Make sure your brake lights, and all other lights, are working
- Keep supplies in your vehicle to help in the event of a breakdown
