Most Flash Flood Fatalities Happen in Cars—Here’s Why
Published Aug 2, 2025
Over 50% of flash flood deaths in the U.S. occur in vehicles. Drivers often misjudge water depth or attempt to cross flooded roads. Just 6 inches of fast-moving water can stall a car, while 12 inches can sweep it away. Poor visibility, pressure to keep moving, and road damage contribute to fatal missteps.
Vehicles and flash floods: a deadly mix
More than half of all flash flood fatalities in the U.S. involve vehicles, highlighting a critical misunderstanding of flood dangers. Drivers frequently underestimate the power of moving water, leading to perilous attempts to cross flooded roadways. It's a startling reality that just six inches of rapidly flowing water can stall a car, while twelve inches can completely sweep it away.
Poor visibility and pressure lead to errors
Several factors contribute to these tragic miscalculations. Poor visibility during heavy rainfall makes it difficult to gauge water depth accurately. The pressure to maintain progress, especially during commutes or urgent trips, can override better judgment. Furthermore, floodwaters can cause unseen road damage, turning a seemingly passable route into a hazardous trap.
Driving through floodwaters is never safe
The Centers for Disease Control and Prevention (CDC) emphasizes that driving through flooded areas is never safe. Floodwaters can conceal debris, potholes, and even washed-out sections of the road. The force of the water can also compromise a vehicle's stability, making it difficult to control.
Prioritize safety: Turn around, don't drown
To avoid becoming a statistic, it is crucial to adhere to the adage: "Turn Around, Don't Drown." When encountering a flooded road, never attempt to cross it. Find an alternate route or wait for the water to recede. Staying informed about weather forecasts and flood warnings is also essential for making safe travel decisions. Remember, your life is worth more than arriving on time. Always prioritize safety over speed when faced with flood conditions.
