Can You Drive If the Exhaust Pipe Is Submerged in Water?

You cannot drive if the exhaust pipe is submerged in water. If the car's exhaust pipe takes in water and the engine stalls, never attempt to restart it forcefully. Instead, immediately call for rescue services and wait for assistance. Below is an introduction to vehicle wading: Introduction: Vehicle wading, as the name suggests, refers to driving through low-lying, waterlogged roads or passing through water. This typically occurs during rainy weather in low-lying areas where inadequate drainage leads to water accumulation on the road. Precautions: Before wading, observe the road conditions carefully; during wading, maintain steady power; after wading, inspect the electrical system.
As someone who drives frequently, I must tell you that you should never continue driving when the exhaust pipe is submerged in water. I once experienced this during a heavy rainstorm. The water flooded the exhaust pipe, and I thought driving slowly would be fine. However, the engine suddenly stalled. Later, at the repair shop, I learned that water had been sucked into the cylinders. When the cylinders compress, water cannot be compressed, causing the pistons and connecting rods to bend or even break, leading to complete engine failure. The repair cost was over ten thousand yuan, not to mention the wasted time. More dangerously, if the water is deeper, the car could get stuck, increasing the risk of being trapped. So, if you notice water reaching the height of the exhaust pipe, immediately turn off the engine, stop driving, and do not attempt to restart. Seek help or call a tow truck. Before heading out, always check the weather forecast to avoid flood-prone areas or consider choosing a car with higher ground clearance for peace of mind.
I think this issue is very important, and everyone should understand the basic principle: when the exhaust pipe is submerged in water and you continue driving, water may enter the engine through the exhaust valve. While the engine is running, the cylinders compress air. Once water is sucked in, it cannot be compressed, which can cause instant damage to internal components. I once saw a neighbor's car suffer engine failure after this happened, costing a fortune to repair. So never take the risk—stop immediately if the water level exceeds the bottom of the car's exhaust pipe. Prevention is also key: choose elevated routes when driving in the rain, and avoid forcing your way through flooded areas. Always keep an emergency kit and rescue equipment in the car. If you encounter flooding, do not attempt to restart the engine—safety is the top priority. Remember this small tip: water entering the engine is more dangerous than it appears, and planning your route in advance can help avoid trouble.
