What is the maximum speed when visibility is 50 meters on the highway?
2 Answers
When driving on the highway with visibility within 50 meters, the maximum speed must not exceed 30 km/h. Relevant information is as follows: 1. Note: Driving on the highway must strictly adhere to the principle of lane separation and each vehicle staying in its own lane. It is not allowed to cross lines, change lanes, or ride on the lane dividing line. 2. Regulations on the maximum and minimum speeds on the highway: The minimum speed must not be less than 60 km/h, and the speed must not exceed 120 km/h. When driving under adverse weather conditions, the driver must reduce speed according to the conditions and speed limit signs.
I've been driving on highways for almost 20 years and encountered many foggy days. When visibility is only 50 meters, never be greedy with speed—I recommend keeping the maximum speed around 20-30 km/h. Why so slow? Because humans need one second to react. Even with the best brakes, at 40 km/h, the braking distance can still exceed 10 meters. Add to that the slippery roads in foggy conditions, and 50 meters can vanish in the blink of an eye. Every time, I immediately turn on the front and rear fog lights, activate the hazard lights, and increase the following distance to more than twice the usual. Most importantly, stay focused and avoid distractions. If you come across an exit, take it immediately to find shelter. Safety first—don’t risk your life for a few minutes. There have been plenty of high-speed fog-related rear-end collisions, and I’ve seen multiple cautionary tales in the news.
