HOW TO DEAL WITH A FLOODED FORD

HOW TO DEAL WITH A FLOODED FORD A flooded ford is one of the most deceptively dangerous hazards on Britain’s roads. What’s normally a simple shallow crossing can turn treacherous in minutes after heavy rain. Even seasoned motorists treat flooded fords with deep respect — and rightly so. Water has a way of humbling even the most capable vehicles.

Here’s how to handle the situation safely, sensibly, and in line with the long-standing principles of good driving.

HOW TO DEAL WITH A FLOODED FORD – 1. STOP WELL BACK AND ASSESS THE SITUATION

As soon as you see a ford flooded, do not drive straight in.
Pull up at a safe distance and take a moment to observe:

• How high is the water?
• Is it flowing quickly?
• Can you see the depth gauge?
• Are other vehicles turning around?

If water has risen above the depth gauge or you cannot see the bottom surface at all, that’s a clear sign the ford is unsafe.

HOW TO DEAL WITH A FLOODED FORD – 2. UNDERSTAND THE RISKS

It only takes 30cm of fast-moving water to float a car.
Just 15cm can cause you to lose steering control.
Floodwater also hides hazards:

• Deep potholes
• Washed-away surfaces
• Debris
• Sudden drops in depth

This is why experienced drivers never rely on guesswork. If there’s doubt, there’s danger.

HOW TO DEAL WITH A FLOODED FORD – 3. DO NOT ENTER IF THE WATER LOOKS DEEP OR FAST

This is the golden rule: If the ford looks flooded, you do not attempt to drive through it.

A flooded ford is very different from a normal shallow crossing. The road may be completely hidden, the force of the water can be far stronger than it appears, and once you’re in, you’re committed — with very little room for recovery.

Even 4x4s get caught out. Modern engines, electrics, and intakes are not designed for floodwater.

HOW TO DEAL WITH A FLOODED FORD – 4. FIND AN ALTERNATIVE ROUTE

This is the correct DVSA-aligned response.

Turn around in a safe place and follow diversion signs or plan a new route. It might add a few minutes to your journey, but it could save your vehicle — and potentially your life.

Remember the old saying every good driving instructor knows:
“Better to arrive late than not arrive at all.”

5. IF IN DOUBT, STAY OUT

This is the attitude the DVSA encourages for new drivers.
Floodwater is unpredictable and unforgiving. A ford that’s normally harmless can turn dangerous after just a short burst of heavy rain.

The sensible, traditional, time-tested answer is simple: Do not take risks with water.

6. REPORT IF NECESSARY

If the flooding looks severe, or if another driver is stranded, call 999 in an emergency or 101 to report a hazard. Local authorities can close the ford until it’s safe again.

SUMMARY: YOUR FLOODED FORD CHECKLIST

• Stop well back
• Assess the water height and speed
• Never enter deep or fast-moving water
• Turn around and find another route
• Report serious flooding

A flooded ford is a hazard you treat with caution and respect. The safest crossing is the one you don’t attempt.

THEORY TEST EXPLAINER: DEALING WITH A FLOODED FORD

A flooded ford is one of the most dangerous water hazards on UK roads. A ford is normally a shallow place where a road crosses a stream or river — but when the water level rises, the crossing becomes unsafe.

The DVSA wants learners to know that you must never attempt to drive through a flooded ford. Depth can rise suddenly, currents can become powerful, and the road beneath the water may be damaged or missing altogether.

Key points to remember:

• Stop well back and assess the situation.
• If the water is deep, fast-moving, or above the depth gauge, do not enter.
• Turn back and find another route.
• Floodwater can hide potholes, sharp debris, and broken road surfaces.
• Even large vehicles can be swept away in surprisingly shallow water.
• After any shallow water crossing (but not a flooded one), lightly test your brakes to dry them.

This is one of those traditional bits of road wisdom that has stood the test of time:
If in doubt — stay out.
