After wading through water, the vehicle should maintain low speed and adopt the method of intermittent light braking repeatedly to generate heat through friction between the brake drum and brake pads, thereby evaporating and draining the water. During driving, if encountering waterlogged roads, as long as the water level reaches two-thirds of the bumper or tire height, continuing to drive through water poses certain risks. Additional Information: 1. While driving, if encountering waterlogged roads where the water level reaches two-thirds of the bumper or tire height, continuing to drive through water is very dangerous. High speed will increase the actual water depth the vehicle passes through, causing rainwater to enter the cabin from the engine compartment or chassis. If observation shows a high water level, it is advisable to detour whenever possible. 2. Besides maintaining low speed when wading through water, try to avoid stopping, shifting gears, releasing the throttle, or accelerating. Instead, pass through steadily at low gear with medium to high throttle, avoiding high speed that could splash large waves or water. 3. Water entering the engine is a very serious issue. Water can enter through the air filter into the intake valve and then into the cylinder block via the intake pipe. In such cases, do not attempt to start the engine again.

After driving for so many years, I often encounter waterlogged sections of the road. After driving through water, it's indeed necessary to maintain a low speed. Why? High-speed driving can cause waves to surge, making it easier for water to rush into the engine's air intake or exhaust system, leading to stalling or even severe damage. Driving at a low speed for a few minutes after passing through water also helps the brake system gradually dry out the accumulated water; otherwise, emergency braking might cause skidding and accidents. I believe safety comes first—don’t rush. Moving steadily and driving slowly for a short distance afterward can save a lot of repair troubles. Additionally, always observe the water depth; if it’s too deep, don’t force your way through to avoid water flooding the cabin and causing more issues. Regular maintenance should include checking the chassis seals—preventive maintenance is crucial.

As a car enthusiast, I care deeply about vehicle health, and driving at low speeds after wading is a crucial technique. Driving at high speeds through water increases water pressure impact, which can cause electronic device short circuits or cooling fan malfunctions due to water adhesion. After wading, driving at a lower speed (e.g., 20-30 km/h) for a few minutes can effectively remove moisture from the brake discs and restore braking power. If you accidentally drive through water at high speed, immediately reduce your speed and keep an eye on the dashboard warning lights. It's advisable to check the tire tread grooves and underbody protection before driving each rainy season to reduce wading risks. Overall, low-speed driving is not just an emergency measure but also a good car maintenance habit, saving both hassle and money.

During driving lessons, the instructor repeatedly emphasized that you must drive slowly after going through water. This is because high-speed driving can cause higher water splashes, which may rush into the engine compartment and lead to sudden stalling. Driving slowly for a short distance (about a few dozen meters) after going through water helps the brake pads evaporate moisture and prevents slipping. I remember the first time I drove in the rain; after going through water, I didn’t accelerate and passed smoothly, significantly reducing the chance of an accident. New drivers should especially pay attention to this—don’t compare your speed with others; just maintain your own pace.
