What is the speed limit on highways in kilometers per hour?

[DiBentley]

Generally, the economical speed for economy cars is 60-80 kilometers per hour, while mid-to-high-end cars have an economical speed of 80-90 kilometers per hour. On regular roads, cars typically travel at around 60 kilometers per hour, whereas on highways, the speed is approximately 100 kilometers per hour, with a legal maximum of 120 kilometers per hour. Additional information: Upon entering the highway, vehicles should accelerate to at least 60 kilometers per hour as soon as possible. Driving too slowly can lead to rear-end collisions. Key points: 1. Speed limits: Highways must indicate lane speed limits, with a maximum speed not exceeding 120 kilometers per hour and a minimum speed not below 60 kilometers per hour. 2. Vehicle type requirements: On highways, the maximum speed for small passenger vehicles must not exceed 120 kilometers per hour, while other motor vehicles must not exceed 100 kilometers per hour, and motorcycles must not exceed 80 kilometers per hour. 3. Lane requirements: For two lanes in the same direction, the minimum speed in the left lane is 100 kilometers per hour. For three or more lanes in the same direction, the minimum speed in the far-left lane is 110 kilometers per hour, and the middle lane's minimum speed is 90 kilometers per hour. If the speed limit indicated by road signs differs from these lane speed regulations, drivers must adhere to the speed limit specified by the road signs.
