What is the correct way to follow a car into a flooded road section?

When following a car into a flooded road section, you should increase the distance from the car in front and proceed with caution at a slow speed. Here are the precautions for driving through flooded road sections: 1. Observe the water conditions: Pay attention to the water depth. Watch the vehicles currently driving through the water and judge whether your vehicle can pass smoothly based on the water level and vehicle position. 2. Observe the road conditions: Determine shallow water areas and areas without potholes by observing other vehicles passing through the water. 3. Driving through water: Always drive at a low speed. For manual transmission vehicles, it is recommended to use second or third gear depending on the water depth. In cases of deep water and heavy traffic, use first gear. Avoid stepping hard on the accelerator, as accelerating is the least advisable. Many drivers worry about stalling and step hard on the accelerator to drive quickly, which often causes more problems.
When driving through a flooded section by following another vehicle, I believe the most important things are maintaining a safe distance and keeping a low speed. That time in heavy rain, I deliberately kept over 20 meters behind an SUV because it created large splashes. I reduced speed to around 10 km/h, engaged a low gear, and maintained steady progress. Before entering, I also checked the water level against the leading vehicle's tires - if it reached above the wheel hub center, I'd detour. Throughout the process, avoid sudden braking or acceleration to prevent water from entering the exhaust pipe. Afterwards, I always visit the workshop to inspect the air filter and undercarriage to prevent rust. Actually, maintaining patience also reduces accident risks - this habit has kept my car free from major repairs for ten years.
From a mechanical enthusiast's perspective, when driving through flooded roads, engine protection should be the top priority. Water entering through the air intake can severely damage the engine, so maintaining a safe distance from the vehicle ahead is crucial to avoid its wake. I recommend entering at a low speed, around 15 km/h, while keeping the engine at higher RPMs to prevent stalling. Judging water depth is key—if it reaches above the wheel hub center, it's best to avoid entering as water pressure can compromise seals. Once inside, avoid sudden braking since wet surfaces may reduce braking effectiveness. Afterwards, inspect spark plugs and wiring as preventive maintenance. These small techniques can significantly extend your car's lifespan.
