What are the precautions for driving in water?

[VanJosie]

There are three main precautions. The specific details are as follows: Slow down or stop to observe: When driving a car and encountering a waterlogged road, as long as the water level reaches two-thirds of the bumper or tire height, there is a risk when driving through the water. High speed will increase the actual water depth the car passes through, causing rainwater to enter the cabin from the engine compartment or chassis. Avoid driving against the waves from large vehicles. If the water level is observed to be high, try to detour and do not force your way through. Do not stop, shift gears, or release the throttle: When driving through water, in addition to maintaining a low speed, try not to stop, shift gears, or release the throttle, and do not accelerate. You should drive through at a steady speed with low gear and medium-high throttle, rather than speeding through and splashing large waves or water. If the car stalls in the water, do not start it immediately: Take measures to tow the car to a safe location with less water as soon as possible. Water entering the engine is a very serious issue; water can enter through the air filter from the intake valve and then into the cylinder through the intake pipe.

As someone who often drives during the rainy season, I strongly advise you to be extremely cautious about water depth. The water level should not exceed half the height of your car's wheels, otherwise, sedans can easily get flooded. Drive in a low gear, first or second gear is the safest, maintain a steady engine speed without sudden acceleration or braking to prevent water from rushing into the air intake and damaging the engine. If your car suddenly stalls, never attempt to restart it immediately, as this can cause severe water intake and engine failure. Quickly exit the vehicle and seek help from a safe location. Once, I underestimated the situation—water only reached the wheel hubs, yet it still caused water damage and costly repairs. I also recommend carrying waterproof clothing and an emergency toolkit to better handle sudden flood surges. In short, driving through water isn't a challenge; prioritizing safety is the golden rule.

When taking kids out, we often encounter rainy days with waterlogged roads. From a family safety perspective, I'd like to share some experience. Before driving through water, stop to observe first - ideally water depth shouldn't exceed ankle height, otherwise splashes may reach the undercarriage and affect electrical systems. Maintain steady speed when driving through, avoid sudden lane changes, turn off AC fans to reduce engine load, and use low gear to prevent water entering the exhaust system. If traveling with children, prepare umbrellas and backup phone batteries - prioritize abandoning vehicle in emergencies. I've also encountered hidden potholes beneath flooded roads - slow speed helps prevent undercarriage damage. Remember: cars can be repaired, but life safety is irreversible.

I've been driving off-road vehicles for years, and wading through water requires skill. When the water depth is no more than half the wheel, proceed cautiously. Use first gear to maintain a steady speed and avoid erratic steering to minimize waves surging toward the front of the vehicle. Note that the air intake is usually located below the front of the car, and water ingress can damage the electronic systems. Stay focused on the water flow ahead while driving, and avoid any strong currents. After wading, stop to check the brakes for any water stains that may affect performance. Carry simple tools like a wrench and a small water pump in case of sudden malfunctions. The key is not to take risks—wisely detouring around deep water areas is the best choice.
