How to Drive an Automatic Car Through Water?

At this point, pull over and observe how other vehicles are passing through. You can use an umbrella, branches from the roadside, or walk through the water yourself to test the depth. This will help estimate whether the vehicle can pass. As long as the air intake doesn't take in water, the vehicle won't stall and can proceed. If it's not suitable, do not force your way through the water.
I've driven through waterlogged roads many times, and the key is to stay steady. First, pull over and stop, then visually assess the water depth—generally, it shouldn't exceed the midpoint of the wheel hub, or the risk of water ingress increases. For automatic transmission vehicles, avoid using D gear; switch to a lower gear like L or S, maintaining engine speed around 2000 RPM. Gently press the accelerator to move slowly—no sudden acceleration or braking, as splashing water could flood the engine. Keep the steering wheel steady while crossing, maintaining a constant speed without changing lanes or hesitating. After passing through, find a flat spot to stop, turn off the engine briefly to let the exhaust pipe drain, then test the brakes for responsiveness (braking distance may be longer on wet surfaces). If the water level feels high and the car starts floating, stop immediately and call for help—safety first, never force your way through deep water.
