Quick Answer
Short answer: Yes, wait for water to recede before driving, as driving through standing water can cause loss of traction, electrical shock, and vehicle damage.
Understanding Flash Flood Risks
When a flash flood occurs, water levels can rise rapidly, often exceeding several feet in a matter of minutes. This can lead to standing water that may appear deceptively calm but can be incredibly deep and treacherous. In fact, according to the National Weather Service, six inches of fast-moving water can knock an adult off their feet, and two feet of water can sweep a small car away.
Assessing Safe Driving Conditions
To determine if it’s safe to drive through the floodwaters, look for signs such as a clear, steady water level, no strong currents, or visible sediment being stirred up. You can also estimate the water depth by observing nearby landmarks or signs. As a general rule, if the water level is above the middle of your vehicle’s wheels, it’s best to wait for it to recede. Remember that even if your vehicle appears to be driving through the water successfully, the electrical systems and air intake can still be compromised.
Preparing for Safe Passage
Before attempting to drive through floodwaters, make sure your vehicle is in top condition, with a full tank of gas, good tire pressure, and a reliable engine. If you do need to drive through the water, do so slowly and at a 90-degree angle to the current, avoiding sudden acceleration or hard braking. Keep your windows and doors closed to prevent water from entering the vehicle, and be prepared to exit the vehicle quickly if the water becomes too deep.
