How to Know if It's Safe to Drive Through Flood Water

Driving through flood waters can be extremely dangerous. Flooding is one of the leading causes of weather-related deaths and vehicle damage. This guide will help you assess whether it's safe to drive through flood water and what precautions you should take.

Recognise Risks Associated with Flood Water

Floodwater can hide several dangers, including:

• Strong currents that can wash your car away.
• Deep water that can stall your engine or enter the cabin.
• Hidden debris, potholes, or road collapses.
• Contaminated water that can harm both health and vehicle components.

General Guidelines for Flood Water Assessment

Follow these guidelines before deciding to drive through flood water:

• Consider the depth of the water. Most cars are swept away by just 12 to 24 inches of moving water.
• Observe the speed of the water. Fast-moving water can be more dangerous even at shallow depths.
• Avoid driving through water that reaches above halfway up your tires, as this can lead to loss of vehicle control.
• If you cannot see the road markings, do not attempt to drive through the water.

Precautions Before Driving Through Water

If you must drive through water, take these safety measures:

• Drive slowly and steadily at about 1-2 mph.
• Use low gear to maintain traction and control.
• Navigating a central portion of the road where the road crown may be higher.
• If possible, follow the path of another vehicle.
• Keep alert and be ready to turn back if it doesn't seem safe.

Actions to Take if Stalled or Stranded

If your vehicle stalls or you become stranded, consider these actions:

• Abandon the vehicle if it’s safe to do so.
• Call for emergency assistance immediately.
• Avoid walking through flood water; as little as 6 inches of fast water can knock an adult off their feet.

Conclusion

When it comes to driving through flood water, the safest approach is often to avoid it whenever possible. By understanding the risks and taking appropriate precautions, you can protect yourself, your passengers, and your vehicle from the dangers associated with flooded roads.
