Essential Tips for Safely Driving Through Flood Water (If You Must)

.

Flooded roads are a common challenge for UK motorists, often leading to a difficult decision: should you risk driving through the water or turn around and find an alternative route?

Driving through deep water can be risky, potentially damaging your vehicle and leaving you with a hefty repair bill. It could also result in your insurance claim being denied if it’s found that you deliberately drove through more water than your vehicle can handle.

Modern vehicles are equipped to handle various weather conditions, but water remains a significant threat, especially to the electrical system and engine. Whenever possible, it’s best to turn around and avoid flooded areas.

If you do encounter flooding on the road, it’s essential to stay calm and proceed cautiously. Even light rain can increase stopping distances, so wet roads require extra care.

Here are some crucial tips to keep in mind:

• Assess the Depth: Avoid driving through water deeper than six inches if it’s standing, or four inches if it’s moving. Park your car and observe other vehicles passing through the water to gauge the depth and how they fare.
• Stick to the Crown of the Road: Where possible, stay on the middle of the road, where it’s often higher. Enter the water slowly in first gear, keeping your engine revs up. This helps maintain momentum and prevents water from entering the exhaust.
• Avoid Speeding: Resist the urge to speed through water. Moving too quickly can force water into the engine, potentially causing serious damage.
• Watch for Oncoming Vehicles: Be cautious of larger vehicles coming from the opposite direction. Their bow waves can flood your car, even if you’re driving carefully.
• Dry Your Brakes: After passing through water, gently apply your brakes to dry them. If you notice any debris in the water, stop safely and check your radiator for blockages.
• 4×4 Drivers Beware: Even in larger vehicles, take care. Enter water slowly and create a bow wave to keep the air intake clear, but be aware that older models may not handle this technique well.
• Don’t Stop Midway: If you stop in the middle of a flooded area, you may lose momentum and struggle to move forward again. If your car stalls, keep the bonnet closed to prevent further water ingress, and safely exit the vehicle.
• Avoid Aquaplaning: Even shallow puddles can cause aquaplaning, where your tyres lose contact with the road, leading to a loss of control. Approach all puddles with caution.
• Mind the Pedestrians: It’s not only inconsiderate but also illegal to splash pedestrians with water. You could face fines and penalty points if caught.

The key to navigating flooded roads is to stay calm, move steadily, and avoid taking unnecessary risks. If possible, find an alternative route and avoid driving through floodwater altogether.
