Drive Fast or Slow Through Water?

[Warren]

When driving through water, it is advisable to proceed at a low speed. However, 'low speed' does not mean crawling at a snail's pace. You should maintain sufficient power to drive slowly, preventing water from entering the exhaust pipe and causing engine failure. When facing waterlogged sections, adjust your approach flexibly based on the water depth rather than rigidly adhering to theoretical rules. Below are the consequences of driving too fast or too slow: 1. Driving too fast can cause stalling: When a car enters a waterlogged area, it stirs up water and mud, creating waves. If the speed is too high, water can splash onto pedestrians or vehicles in adjacent lanes, severely affecting visibility and driving safety. Moreover, if the water is deep enough, splashed water may enter the engine's air intake, causing the car to stall. 2. Driving too slow can lead to exhaust backflow: The exhaust pipe has a certain thrust that can block water from entering when submerged. However, if the speed is too slow and the water is too deep, the exhaust pipe's thrust may not be enough to prevent water from flowing back. Therefore, while driving slowly through waterlogged sections, the speed should not be excessively slow.
