In foggy conditions with visibility less than 50 meters, the following distance must be within the visible range. You should turn on the fog lights, low beams, position lights, front and rear position lights, and hazard warning lights. When driving on highways in foggy weather, the speed should not exceed 20 kilometers per hour, and you should exit the highway at the nearest exit as soon as possible. 1. When visibility is less than 200 meters: Turn on the fog lights, low beams, position lights, and front and rear position lights. The speed should not exceed 60 kilometers per hour, and maintain a distance of more than 100 meters from the vehicle in front in the same lane. 2. When visibility is less than 100 meters: Turn on the fog lights, low beams, position lights, front and rear position lights, and hazard warning flashers. The speed should not exceed 40 kilometers per hour, and maintain a distance of more than 50 meters from the vehicle in front in the same lane.

I think when visibility is less than 50 meters, you should maintain at least a 100-meter distance between vehicles. This is because in foggy, rainy, or snowy conditions, braking distances become longer, requiring more safety buffer. My usual driving habit is to adjust the distance based on speed—for example, maintaining three times the car length when driving under 30 km/h to avoid rear-end collisions. Also, remember to turn on the fog lights and rear lights to help the car in front see you. Once encountering low visibility, I immediately slow down to 20 km/h while staying focused on observing road conditions. Safe driving isn't just about distance—it also involves avoiding sharp turns or sudden braking to maintain vehicle stability. It's like feeling your way forward; it's better to leave extra space than to take risks.

As an ordinary driver who frequently drives in mountainous areas, I try to maintain a distance of over 80 meters when visibility is less than 50 meters. Once in heavy fog, I got too close and almost hit a truck, which made me extra cautious ever since. Keep your speed under 40 km/h and use the time interval method—counting three seconds to confirm the distance. Also, check if the braking system is functioning properly and remind yourself not to be influenced by other drivers' pace. Dust or condensation often accumulates on the windows, so remember to clean them promptly for better visibility. All these details combined ensure safety, as life is more important than time.

In driving practice, when visibility drops below 50 meters, the following distance should be doubled—for example, increasing from the usual 40 meters to 80 meters. Maintaining a slow speed is crucial, reducing to below 25 km/h, and utilizing vehicle safety systems like ABS for assistance. I've noticed many drivers neglect checking their rearview mirrors; it's best to scan the surroundings every 5 seconds. Reaction times may be delayed in sudden situations, so the route in advance can help avoid accidents. In short, prioritize caution—better safe than rushed.

I believe that when visibility is less than 50 meters, the following distance should exceed 50 meters, depending on speed: 30 meters is sufficient at 20 km/h, but over 60 meters is needed at 30 km/h. Considering wet road conditions where tire grip decreases, it's wise to leave extra buffer space. I make it a habit to place reminder stickers on the dashboard to help memorize these rules. When using air conditioning, avoid letting the airflow distract your focus. Safety is no trivial matter—developing good habits can prevent accidents.

From a safety perspective, when visibility is less than 50 meters, it is recommended to maintain a minimum following distance of 70 meters, as visibility is directly related to reaction time. I would reduce speed to under 20 km/h and activate the full lighting system to enhance visibility. It's also advisable to keep emergency tools like reflective vests in the vehicle as a precaution. Maintaining the right driving mindset is crucial—avoid shortening the distance due to impatience. This approach ensures a smooth and safe arrival at your destination.
