What is the general speed limit on highways?

[SanSophia]

Highways have marked speed limits for each lane. Generally, the maximum speed should not exceed 120 kilometers per hour, and the minimum speed should not be less than 60 kilometers per hour. Below are specific details about highway speed limits: Two lanes in the same direction: On a highway with two lanes in the same direction, the minimum speed for the left lane is 100 kilometers per hour, and the minimum speed for the middle lane is 90 kilometers per hour. When the speed limit indicated by road signs differs from the above lane speed regulations, drivers must follow the speed limit indicated by the road signs and must not violate them.
