What is the standard width of a motor vehicle lane in meters?

For a two-way four-lane road, it is 2x7.5 meters; for a two-way six-lane road, it is 2x11.25 meters; for a two-way eight-lane road, it is 2x15 meters. According to road conditions and traffic needs: Roads are divided into motor vehicle lanes, non-motor vehicle lanes, and pedestrian walkways, with motor vehicles, non-motor vehicles, and pedestrians traveling in their respective lanes. If the road is not divided into motor vehicle lanes, non-motor vehicle lanes, and pedestrian walkways, motor vehicles travel in the middle of the road, while non-motor vehicles and pedestrians travel on both sides. When motor vehicles are driven on the road: They must not exceed the maximum speed indicated by speed limit signs. On road sections without speed limit signs, a safe speed should be maintained. When driving at night or on sections prone to danger, or under weather conditions such as sandstorms, hail, rain, snow, fog, or icy roads, the driving speed should be reduced.
I see that the standard width of urban motor vehicle lanes generally ranges from 3.0 to 3.5 meters. For example, main roads are usually 3.5 meters wide, allowing cars to drive steadily and large vehicles to pass with some difficulty. Suburban and highway lanes are wider, possibly up to 3.75 meters, because of higher speeds and greater traffic volume, requiring sufficient space to prevent collisions. If the width is too narrow, novice drivers may feel nervous, and traffic jams can become highly stressful. On the other hand, excessively wide lanes waste land resources and may encourage speeding. Some roads in older urban areas are as narrow as just over 3 meters, making driving quite nerve-wracking. Lane width should be designed according to road classification, with safety as the top priority. Whenever I drive on narrow roads, I slow down and remind myself to carefully observe both side mirrors.
