When driving in foggy weather, vehicles should turn on the headlights, clearance lights, and rear position lights. Here are some relevant introductions about driving in foggy weather: 1. Precautions: Control the speed. When the visibility is less than 500 meters but greater than 200 meters, the speed should not exceed 80 km/h; when the visibility is less than 200 meters but greater than 100 meters, the speed should not exceed 60 km/h; when the visibility is less than 100 meters but greater than 50 meters, the speed should not exceed 40 km/h; when the visibility is within 30 meters, the speed should be controlled below 20 km/h. 2. Tips: Use the horn frequently, maintain a safe distance, and use fog lights. When two vehicles meet, honk the horn to alert the oncoming vehicle, and turn off the fog lights to avoid dazzling the other driver.

I believe that driving in foggy conditions requires turning on both front and rear fog lights, which is a lesson from my over ten years of driving experience. Front fog lights help illuminate the road ahead, especially in thick fog where regular headlights just create glare and make it hard to see anything. Rear fog lights ensure that vehicles behind can spot me, preventing rear-end collisions. I remember last winter when I was driving on a business trip and heavy fog suddenly rolled in—I immediately turned on my fog lights and made it home safely. In contrast, a friend of mine didn’t use them and nearly hit a guardrail. Traffic regulations also mandate the use of fog lights when visibility drops below 100 meters, with fines and penalty points for non-compliance. A safety tip: avoid using high beams, as they only worsen visibility in fog. Instead, pair fog lights with low beams, drive slowly, and maintain a safe distance. In short, skipping fog lights isn’t just a violation—it’s gambling with your life.

How to Check for a Flood-Damaged Car?

To determine if a car has been flood-damaged, you can inspect the vehicle's chassis to observe the extent of corrosion. During the repair process of flood-damaged cars, most repair shops will not replace the fog lights as long as they are still functional. When you open the car door, if you can detect a noticeable musty smell, it is certain that the car has significant issues.

How to Open Car Windows for Maximum Coolness?

Opening only the driver's side or passenger's side window allows smoke inside the car to dissipate quickly, which is even more effective than opening the sunroof. Just a narrow crack is sufficient. Simultaneously opening the left front and right rear windows, or the right front and left rear windows, minimizes wind noise while allowing rapid air circulation inside the car for optimal ventilation. Opening all three remaining windows creates strong airflow, quickly ventilating and eliminating odors.

How to prevent a car from being flooded?

Place the car into a large bag and seal it to prevent any contact with rainwater. The waterproof effect is rated five stars, just hoping it won't be punctured by sharp objects. Use bricks or other objects to raise the car by 10-20 centimeters to prevent rainwater from reaching the chassis. There is a type of parking lot called a "rooftop parking lot," which is characterized by its height above ground level, making it less likely to be flooded.
