Can You Drive If Water Gets Into the Car Exhaust Pipe?

[SanJaxon]

You can drive if water gets into the car exhaust pipe. Generally, water in the exhaust pipe does not affect driving because the water can only stay inside the exhaust pipe. Relevant information is as follows: If water in the exhaust pipe causes the engine to take in water, the consequences can be severe. If only the exhaust pipe has water, the accumulated water should be removed as soon as possible to prevent impurities in the water from clogging the three-way catalytic converter or damaging the oxygen sensor. To drain the water, simply increase the throttle to expel the water through the exhaust. Water in the exhaust pipe may cause blockage, leading to poor exhaust flow and engine stalling. However, in this case, the engine may not necessarily take in water—it’s just what’s commonly referred to as being "choked out." There’s no need to worry; as long as you wait for the water to drain, you can restart the car.
