Is it correct to shift into high gear and drive quickly through flooded roads?

[OGraham]

When driving through flooded roads, it is incorrect to shift into high gear and drive quickly. Instead, you should use a low gear to ensure the vehicle has sufficient driving force. Enter the water smoothly to prevent splashing water from entering electrical equipment, which could cause short circuits. Maintain medium engine speed and a steady speed, avoiding stopping, shifting gears, or making sharp turns while driving through the water. Pre-drive inspection: Before entering the water, someone must check the depth, width, water flow speed, the extent of damage to the road caused by the water, and whether the water level is rising or falling. Based on these observations, determine whether it is safe for the vehicle to pass. If the conditions are not safe, do not risk driving through. Protective measures: When it is confirmed that passage is possible, take necessary protective measures for the vehicle, such as closing the louvers, raising the position of the battery, waterproofing the electrical system, and elevating the exhaust pipe outlet.

I've been driving for twenty years and often encounter waterlogged roads during rainy days. Last time after a heavy rain, the city was full of puddles. In a hurry, I shifted to a high gear and charged through, only for water to get sucked into the exhaust pipe, causing the car to stall instantly and get stuck in the middle of the road, nearly getting rear-ended. The towing and repair cost over six thousand, a profound lesson. Now when facing flooded roads, I never use high gear to rush through. Instead, I switch to low gear and drive slowly—engine revving high but the car moving slow—keeping the water flow steady and reducing the risk of it being sucked into the engine. If the water depth exceeds half the tire height, I decisively detour or stop and wait. How important safe driving is! Speeding not only damages the car but also endangers oneself and others. Better to leave a bit slower than to take the risk.

Driving through waterlogged roads requires scientific approaches. When shifting to a high gear for rapid passage, the high-speed rotation of the wheels creates large splashes, increasing water pressure that can easily flood the engine's air intake, leading to hydro-lock and engine failure. Conversely, shifting to a low gear and maintaining a steady, slow speed reduces splashes and pressure differentials, protecting mechanical components. I make it a habit to anticipate water depth in advance; if the water exceeds the center height of the wheel rim, I detour to avoid any acceleration. Slow passage also enhances tire grip, reducing the risk of slipping on wet surfaces. Remembering this physical principle helps prevent mishaps, saving substantial repair costs and ensuring peace of mind in daily life.

Don't rush when driving through water. First, check the depth of the water—shallow water is passable, but avoid using high gears to dash through. Second, shift to a low gear like first, maintain steady throttle, and proceed at a constant speed. Third, drive slowly to minimize splashing and prevent water from entering the engine. Avoid sudden acceleration or braking during the process, keeping movements smooth. If the water is too deep, simply avoid it. This method is simple, effective, protects your vehicle, and ensures safety, suitable for both beginners and experienced drivers.

Saving money is my driving philosophy. Speeding through waterlogged roads in high gear might save a few minutes, but the cost is steep: thousands in engine repair fees if water gets in. I opt for low gear and slow driving—engine noise may be loud, but the speed is gentle, minimizing waves and protecting the car. I always estimate water depth; if it’s above knee level, I don’t take the risk. Moving steadily also saves fuel and reduces wear, avoiding hefty future expenses. Smart driving is both economical and practical.

When traveling with family, safety comes first when driving through water. I never rush through in high gear, as that's reckless and can easily lead to stalling or losing control. Instead, I drive slowly in low gear for about ten kilometers, keeping the car quiet and fearless, with the engine running smoothly and free from water ingress. If the water depth reaches above the calves, I detour to ensure safety. Be extra cautious when traveling in the rain, slow down the speed, and prioritize the safety of the whole family getting home safely. Develop good habits to reduce the risk of accidents.
