Should I start a car parked in flood water?
Starting a flooded vehicle carries a realistic risk of water entering the engine intake, even if the car wasn't running. This leaves people unsure whether they should attempt moving to higher ground or avoid starting it completely and get it towed. However, some cars will run as they should and have no issues once they are professionally cleaned and dried.
