What is the general speed of a car in kilometers per hour?

[JoannaDella]

Here is an introduction related to car speed: 1. Article 78: Highways should indicate the driving speed of the lanes, with the maximum speed not exceeding 120 kilometers per hour and the minimum speed not lower than 60 kilometers per hour. 2. For roads with 2 lanes in the same direction: the minimum speed of the left lane is 100 kilometers per hour; for roads with 3 or more lanes in the same direction, the minimum speed of the leftmost lane is 110 kilometers per hour, and the minimum speed of the middle lane is 90 kilometers per hour. If the speed indicated by the road speed limit signs is inconsistent with the above lane speed regulations, the speed indicated by the road speed limit signs should be followed.
