When a motor vehicle encounters a flooded road or bridge, it should stop to assess the water conditions and proceed at a low speed only after confirming safety. Here is some information about motor vehicles: 1. Definition: A motor vehicle is a "vehicle" driven by its own power unit, equipped with two or more wheels, not requiring overhead lines or tracks, capable of traveling on roads or off-road surfaces, primarily used for transporting people, goods, or performing specific tasks. 2. Classification: Vehicle classification is a fundamental aspect of various vehicle standard systems. Different standards have different classification methods, which may cross-reference each other while also having their own focuses and distinctions. Only by correctly understanding and grasping the basic concepts and applicable scopes of different classification methods, and clarifying the connotation and extension of specific definitions, can one accurately apply relevant standard clauses in motor vehicle inspection practices, precisely determine vehicle types, and correctly issue inspection conclusions.

When encountering flooded roads while driving, I always exercise extreme caution. First, I stop the car to carefully assess the water depth. If the water level exceeds half of the wheel height, I absolutely detour or wait for the water to recede, never attempting to force my way through. Only after confirming it's safe to proceed do I engage a low gear and slowly enter, maintaining a steady speed of 10 to 15 km/h, avoiding sudden acceleration or braking to prevent water from surging in. During the process, I turn off the air conditioning to reduce the risk of the engine sucking in water. After safely passing through, I immediately lightly press the brakes a few times to dry the brake discs. In bad weather, carrying a water depth gauge provides more reliable measurements. Regularly checking the vehicle's underbody sealing helps prevent water ingress issues, especially getting a maintenance check before the rainy season for added peace of mind. A dashcam helps me record road conditions, keeping me calm in emergencies. Remember, safety is paramount—better to go slow than rush and risk vehicle damage or personal injury. Driving isn't a gamble; patience pays off.

One time during a heavy rainstorm, I was driving home and encountered a large puddle. Confidently, I charged through it, only for the engine to stall. The repairs were expensive and caused a lot of inconvenience, which made me reflect deeply. Now, when I approach flooded roads, I assess the water depth. If it's unclear, I get out of the car to check, ensuring it's safe before proceeding slowly in first or second gear at a steady speed not exceeding 15 km/h. I turn off the air conditioning and focus on throttle control to prevent water from splashing in. After passing through, I immediately test the brakes for any abnormalities; otherwise, I call for assistance. Chatting with fellow car enthusiasts about water-crossing techniques has been very practical, such as keeping an emergency toolkit handy and checking routes in advance during bad weather to avoid flooded areas. During maintenance, I pay attention to the exhaust pipe's sealing to prevent rust. These experiences have helped me avoid repeating the same mistakes—slowing down is safer.

When encountering flooded roads while driving, stop the car first to assess the water depth and ensure there's no risk before proceeding. Drive at a slow, steady speed of about 10 km/h when wading through water, avoiding acceleration or sudden braking. Turn off the air conditioning and fans to reduce water intake. After passing through, lightly press the brakes to dry the discs. Avoid entering deep water to prevent the car from being submerged—safety comes first. Regularly check the vehicle's drainage system and perform simple maintenance steps to protect your beloved car.
