What is the speed limit on Yanjing Expressway?

[OElliana]

Yanjing Expressway has different speed limits depending on the lane division of the road section. For roads with 2 lanes, the minimum speed in the left lane is 100 km/h; for roads with 3 or more lanes in the same direction, the minimum speed in the leftmost lane is 110 km/h, and the minimum speed in the middle lane is 90 km/h. Regardless of the lane type, the maximum speed must not exceed 120 km/h. Expressway speed limit values: The speed limit on expressways must not exceed 120 km/h, and the speed limit value should be a multiple of 10 km/h. The difference in speed limits between two adjacent sections should not exceed 20 km/h. For highway interchanges, the speed limit signs on the mainline, deceleration lanes, and exit ramps should not differ by more than 30 km/h. Speed limit sign design: Speed limit signs should be designed to be simpler, clearer, and more aesthetically pleasing. They should be placed at the beginning of the speed-limited section and must not be obstructed by roadside trees, structures, or other traffic signs. Additional signs should be installed as needed.
