Highway drainage generally uses open ditches. Especially in mountainous and hilly areas, where the ground slope is large and water flows quickly, open ditches can fully utilize their drainage function. Urban road drainage is systematic and more complex, which can be divided into separate systems and combined systems (see drainage system).

That day I was driving in heavy rain, and the water on the road almost caused me to skid and lose control. Now I know slowing down is key—reduce speed to 20-30 km/h in areas with standing water, maintain a low gear, and avoid sudden acceleration or braking to minimize the risk of skidding. Increase your following distance to at least three car lengths to prevent water splashed by the vehicle ahead from obstructing your view. If the water depth reaches the middle of your wheels, it's best to find an alternate route rather than forcing your way through to avoid water damage or stalling. Turn on your wipers and keep your front and rear lights on so other drivers can see you. I always keep an absorbent cloth in the trunk as a backup—if water gets into the exhaust, it can help absorb some moisture in an emergency. These tips have helped me navigate many rainy days safely.

As a car enthusiast, I'm particularly concerned about the damage water accumulation can cause to my vehicle. I regularly check the tire tread depth, ensuring it's at least 3mm for better water drainage and anti-skid performance. I also frequently inspect the brake pads to ensure quick response on wet roads. Since standing water can easily cause chassis corrosion, I always apply anti-rust spray after each car wash. When encountering waterlogged roads, I avoid large puddles and drive through at a steady speed to prevent splashing muddy water that could stain the paint. I keep emergency tools in the car, such as a water vacuum cleaner, to immediately handle any water intrusion. For long-term protection, I recommend parking in elevated areas to avoid low-lying zones where water might accumulate and soak the car. Proper saves repair costs in the long run.

Last heavy rain, I was a new driver on the road, and the waterlogged sections made me nervous. I learned to pass slowly, reducing speed to 15-20 km/h, keeping hands steady on the wheel without sudden movements. If the tires skid, don't brake hard—just gently ease off the accelerator. Navigation helped me avoid known deep water spots, saving a lot of trouble. When seeing deep water, I first pulled over to observe how other cars passed before driving through. Be careful not to splash pedestrians—it's impolite. Don't panic if the wheels get submerged; keep moving forward to avoid water entering the engine. These small tips turned my nervousness into confidence.

With 20 years of driving experience, I deeply understand that standing water is an invisible killer. The primary safety principle is to drive slowly, keeping the speed within a reasonable range, as waterlogged areas can easily cause skidding and loss of control. Maintain a sufficient following distance—three times the usual distance—to prevent accidents. Lights must be turned on, using all-weather lighting to enhance visibility and avoid rear-end collisions. All passengers must wear seat belts, as they can easily be thrown out when the road is slippery due to water. Understanding road conditions is crucial; listen to broadcasts or use apps to check for waterlogging forecasts and avoid hazardous areas. Developing these habits can significantly reduce the accident rate.

I always plan my trips in advance, checking the weather forecast before encountering waterlogged areas and preparing an emergency kit. The kit includes absorbent mops and snow chains to prevent accidents. I familiarize myself with local flood-prone spots and use map apps to avoid hotspots. When driving through water, I choose shallow areas to pass smoothly, maintaining a steady speed without sudden acceleration. During the rainy season, I regularly inspect my tires and braking system to ensure strong traction. If waterlogging is severe, I report it to the relevant authorities for drainage repairs, contributing to public safety. These steps help me navigate rainy days smoothly.
