Should a car pass through waterlogged sections quickly or slowly?

When driving through waterlogged sections, a car should pass slowly. When driving on flooded roads, you should engage a low gear to maintain sufficient power for the vehicle, slowly and steadily enter the water, keep the steering steady, and pass through at a constant speed without shifting gears, stopping, or making sharp turns. The correct way to drive through waterlogged sections: First, stop and observe the depth of the water to see if it exceeds half of the wheel hub. If it does, do not proceed further. If it is passable, shift to gear 1 or 2 to ensure the engine runs at high RPM, providing sufficient power. Open the window slightly to allow ventilation in case the car gets submerged and the doors cannot be opened. After entering the waterlogged section, drive at a low speed and try to pass through the middle of the road, as the center is usually higher than the sides, with shallower water. Post-water crossing measures: Check the electrical system. Immediately remove any explosive materials from the electrical components, dry them, and reinstall the fan belt. Inspect each gearbox for water ingress, check if there are any obstructions between the radiator fins, assess tire damage, and look for any debris or plants tangled under the chassis. Clean the vehicle promptly to restore braking effectiveness. Do not attempt to start the engine before confirming that the electrical system, engine components, and other parts are free of water to avoid further damage.
As a seasoned driver who frequently takes long-distance trips, I believe it's crucial to drive slowly when crossing waterlogged sections. Speeding through poses too much risk—the splashing water can rise high and easily enter the engine intake. If the engine ingests water and stalls, the car could be left stranded right in the middle of the road. I learned this the hard way when I was younger—I tried to show off by rushing through, only to flood the engine and incur hefty repair costs. Moving slowly and steadily at around 5 to 10 km/h reduces water pressure, protecting the undercarriage and electronic components while preventing skidding or loss of control. Before crossing, it's best to step out and check the water depth—if it exceeds half the height of the tires, don't take the risk. Remember, safety comes first. Driving slowly isn't about wasting time—it's about ensuring both you and your car make it home safely. That's the long-term strategy.
