Is a 60 km/h Speed Limit on Highways Reasonable?

[LaGenevieve]

Highways should clearly indicate the speed limits for each lane, with the maximum speed not exceeding 120 kilometers per hour and the minimum speed not less than 60 kilometers per hour. Additional information: 1. Speed requirements for different vehicle types: On highways, the maximum speed for small passenger vehicles should not exceed 120 kilometers per hour, other motor vehicles should not exceed 100 kilometers per hour, and motorcycles should not exceed 80 kilometers per hour. 2. Speed limit requirements for different lanes: For roads with two lanes in the same direction, the minimum speed for the left lane is 100 kilometers per hour; for roads with three or more lanes in the same direction, the minimum speed for the leftmost lane is 110 kilometers per hour, and the minimum speed for the middle lane is 90 kilometers per hour. If the speed indicated by road speed limit signs conflicts with the above lane speed regulations, drivers should follow the speed indicated by the road speed limit signs.
