In short: Can I drive my car through flood water?
The most recent flood has once once more raised the question for car drivers: Can I drive my car on a flooded road – or is there even a risk of an electric shock in an electric car?

Question from Chantal to the Viva expert team:
In view of the recent flooding, I ask myself: How high can the water be so that I can still drive through it safely with my car? And how regarding in an electric car; am I not risking an electric shock?
Answer:
Youtube and Co. are full of videos in which water crossings ruin cars. Because that happens much faster than expected, at most “real” off-road vehicles (but not SUVs) tolerate it well. Therefore: When in doubt, you should stay dry. If only because the partially or fully comprehensive insurance replaces the flooded, parked car (unless the region was already an endangered area), but a car that has been driven into the water through gross negligence usually does not. If the water level is at the height of the seat cushions or if there is water in the engine, it is usually a total loss.
“Only drive at walking pace in the water and keep accelerating.”

If the water almost reaches the floor of the vehicle (often 15 to 20 centimeters), you can usually dare; it reaches up to the height of the doorsteps, better not. Only drive at walking pace in the water, never stand still and constantly accelerate. Water fountains are as entertaining as they are: The fatal end comes when the water roll penetrates the engine compartment and paralyzes the electrics, floods the air intake of the engine or sometimes when you take your foot off the gas and water penetrates the exhaust pipe. Very important: If the engine stops, do not start it once more! Then a tow truck is needed, otherwise the damage will be worse.
“Electric cars tend to be even more water-safe.”

And electric cars? They tend to be even more waterproof. Battery and motors are encapsulated. The motor does not need air, so it cannot suck in water. Of course, the electronics are just as sensitive. However, there is no risk of electric shock: as in the case of a crash, the high-voltage components are immediately disconnected from the battery. However, to be on the safe side, you should never touch the orange cables – not even when it is dry.
If the water is at the height of the doorstep, you shouldn’t risk anything. If it only goes to the vehicle floor, you can usually dare.
