We all have seen videos of drivers driving through flooded roads. Some make it safely to the other side and some may be rescued by passers-by. Sometimes the vehicles are washed away in the strong currents causing loss of lives.

After the vehicle has been through flooded roads get the vehicle examined by a mechanic. Running it, or even just trying to start it, may cause severe damage if water has gone anywhere it should not have.
