How To Drive Safely Through Floods

During the rainy season, we often encounter a water-logged road. And often, avoiding floods is not driver's best option.


When you are driving through floods, the water may get inside the car engine which then causes an engine breakdown. Therefore, here are few ways to minimize car engine damage and drive safely through floods:

  1. Keeping a distance with the car in front and follow the water wave
    While crossing the flood, make sure there is a safe distance between your car and the car in front, as well keep your attention to the water wave. When driving through the flood, there will be a bow wave in front of the vehicle. This wave will move forward at a certain speed and leave a shallower water gap behind it. You can use this moment to follow the wave slowly. Maintain your car momentum so that the vehicle and the waves remain at the same speed. By doing this, your car will go through a shallower flood.
  2. Maintain low engine rotation
    There is a myth that while driving through floods, you need to maintain high engine rotation to avoid engine breakdown or prevent water from entering through the exhaust. The fact is when the car drives through floods with higher rpm, the machine air suction power also increases and causes more water reaching into the engine room. This can create water hammer symptoms and engine breakdown. Therefore, make sure to maintain your car at low rotation around 1.500-2.000 rpm. Even though the water still gets into the engine room, the damage is lesser compared to using high rotation.
  3. Avoid using half clutch
    It is recommended for manual cars to release the clutch as much as possible when passing through floods. Using a half clutch method too often will only increase the chance for a burnt clutch and increase high engine rotation.

Those are the 3 ways you can do when facing a flood while driving on the road. By implementing these 3 ways, you can now safely drive through floods. But if the water is too high, don't force to cross it! Keep measuring the possibility of your car, whether it is possible to pass it or not. Keep calm and drive safely.
