What is the safe distance on the highway with 200 meters visibility?
2 Answers
When visibility on the highway is below 200 meters, maintain a distance of more than 100 meters from the vehicle in front in the same lane. For both the driver and the driver ahead, maintaining a safe distance of more than 100 meters is more beneficial than harmful. Additionally, if visibility is less than 200 meters, the driver cannot clearly see the road conditions ahead. Therefore, it is essential and necessary to always keep a distance of more than 100 meters. When visibility is less than 200 meters, turn on fog lights, low beams, marker lights, and front and rear position lights, and do not exceed a speed of 60 kilometers per hour, maintaining a distance of more than 100 meters from the vehicle in front in the same lane. When visibility is less than 100 meters: turn on fog lights, low beams, marker lights, front and rear position lights, and hazard warning flashers, and do not exceed a speed of 40 kilometers per hour, maintaining a distance of more than 50 meters from the vehicle in front in the same lane. When visibility is less than 50 meters: turn on fog lights, low beams, marker lights, front and rear position lights, and hazard warning flashers, do not exceed a speed of 20 kilometers per hour, and exit the highway from the nearest exit as soon as possible.
When driving on the highway in foggy conditions with 200 meters of visibility, it's essential to maintain a safe following distance of at least 200 meters. I've encountered similar weather on the highway myself, reducing my speed to around 80 km/h, and I used roadside milestones to estimate distance. For example, counting 3 seconds from a landmark to ensure I don't reach it within that time, which roughly equals 200 meters. In heavy rain or strong winds, I increase the distance to 250 meters to allow more reaction time. I remember once following too closely, and the car in front suddenly braked—it was a close call. Now, I've made it a habit to leave extra space. Safety comes first; driving slower in such low visibility helps control risks and even saves fuel and stress. In short, don’t worry about delays, avoid risky overtaking, and stick to the rules—it’s the most reliable approach.
