Regardless of the number of lanes, the basic speed limit regulations are a minimum of 60km/h and a maximum of 120km/h. Depending on the number of lanes, the specific limits are as follows: for two lanes, the left lane has a minimum of 100km/h and the right lane a minimum of 60km/h; for three lanes, the left lane has a minimum of 110km/h, the middle lane a minimum of 90km/h, and the right lane a minimum of 60km/h; for four lanes, the far left lane is 110km/h, the second left lane is 100km/h, the third left lane is 90km/h, and the far right lane is 60km/h. No matter which lane, the maximum speed is not allowed to exceed 120km/h. Highways are classified as high-grade roads. Although different countries have different names for highways, they all refer to roads with more than four lanes, separated directions, fully controlled access points, and all using grade-separated interchanges. Generally, highways are designed to accommodate speeds of 120km/h or higher, with road widths of more than four lanes. A median divider is set up in the middle, using high-grade pavement materials like asphalt concrete or cement concrete, equipped with complete signage, markings, signals, and lighting devices; pedestrians and non-motorized vehicles are prohibited from using the road, with other routes accessed via grade-separated interchanges, pedestrian overpasses, or underpasses.
