[Angela]

On highways, the maximum speed for small passenger cars must not exceed 120 kilometers per hour, other motor vehicles must not exceed 100 kilometers per hour, and motorcycles must not exceed 80 kilometers per hour. Detailed information is as follows: 1. According to the 'Implementation Regulations of the Road Traffic Safety Law of the People's Republic of China': Article 78 states that highways should indicate the speed limits for lanes, with the maximum speed not exceeding 120 kilometers per hour and the minimum speed not less than 60 kilometers per hour. 2. Speed limits vary based on the number of 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 limit indicated by road signs differs from the above lane speed regulations, drivers should follow the speed limit indicated by the road signs.
