What is the minimum speed when visibility is less than 200 meters?
2 Answers
When visibility is less than 200 meters, turn on the fog lights, low beam lights, outline marker 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. Below is relevant information: When driving on highways under low visibility weather conditions such as fog, rain, snow, sandstorms, or hail, motor vehicles should comply with the following regulations: 1. When visibility is less than 200 meters: Turn on the fog lights, low beam lights, outline marker 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 beam lights, outline marker 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. 3. When visibility is less than 50 meters: Turn on the fog lights, low beam lights, outline marker lights, front and rear position lights, and hazard warning flashers. The speed should not exceed 20 kilometers per hour, and exit the highway as soon as possible from the nearest exit. 4. In the above-mentioned situations: Highway management departments should display speed limits, distance maintenance, and other prompt information via message boards or other means.
I've been driving for many years and often encounter heavy fog on highways. When visibility drops below 200 meters, I always reduce my speed to under 60 km/h to allow sufficient reaction time. Driving too fast increases the risk of rear-end collisions, especially in poor visibility conditions. Once on the highway, the fog suddenly thickened with visibility less than 200 meters, and I promptly slowed down to 50 km/h, narrowly avoiding a minor accident. Maintaining a safe following distance is also crucial—about twice the visibility distance—to ensure enough space. Don’t forget to turn on your low beams or fog lights, as they make your vehicle more noticeable to others. In rainy or icy conditions, drive even slower, as slippery roads increase braking distance. Driving cautiously is always better than risking an accident—safety comes first.
