What you need to know about flooded vehicles
When severe weather hits, fleets need to be prepared for the challenges of flooded vehicles. Unpredictable conditions can be a major threat, but with the right strategies, you can protect both yourself and your fleet vehicle.
Understanding the risks of flooded vehicles
According to the CDC, each year floods cause more deaths than any other thunderstorm-related hazard – and those deaths commonly happen when a vehicle is driven into flood water. Remember to follow the advice of the National Weather Service: “Turn Around and Don’t Drown,” as only 12 inches of flowing water can carry away a vehicle.
Long-term impact of flood damage
- Resale value: Flood damage can drastically affect a fleet vehicle's resale value. Before investing in repairs, consider the potential long-term cost impact. While minor repairs might be feasible, damage to interiors or electronic systems can have lasting effects.
- Mechanical system compromise: Flood water typically leaves a "water line" after it recedes. Debris or contamination in the water will deposit particles on the surface, leaving a visible line showing water depth. If a vehicle is submerged up to 12 inches or more, have it towed for a thorough mechanical examination before starting the engine as water infiltration can make mechanical systems inoperable.
What to do if your fleet vehicle is flooded
Don’t start the engine
- If water entered the cabin, don’t try to start your engine as the electric components have likely been damaged. In most vehicles, the airbag and restraint control module are mounted to the floor beneath the carpet. Moisture can wick into fabric and affect areas even above the water line.
- If the vehicle stalled out while driving through standing water, it’s possible that the engine is damaged from ingesting water.
Get more information
- Find out the source of the water – fresh, brackish or salt water – and how long the vehicle spent submerged.
- Brackish and salt water are the most damaging as they cause corrosion when they’re in contact with electronics. If the vehicle’s electrical system has been compromised by anything other than fresh water, repair is typically not an option.
Handle hybrid and electric vehicles carefully
- If there’s any chance that your hybrid or electric vehicle was flooded, don’t start or charge it.
- Don’t touch the vehicle or step into standing water within a 10-foot radius because of high voltage hazards. The best thing to do is to call your accident management provider and report the damage.
- If you’re certain your vehicle was not flooded, and you need to use emergency charging cables to charge your electric vehicle, be extremely cautious. These cables don’t offer the same level of protection as a wall box charger does. Take these basic precautions:
- Don’t use them with bare feet.
- Never use them on wet surfaces.
- Don’t have direct contact with the vehicle, other than when connecting the cable.
- Never disconnect the cable while it is in use.
