Is the speed limit for large trucks on highways 100 or 80?

[McSpencer]

Large trucks on highways have speed limits of both 100 and 80. The following are the relevant regulations: 1. Regulation 1: Highways shall 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. 2. Regulation 2: On highways, the maximum speed for small passenger vehicles shall not exceed 120 kilometers per hour, other motor vehicles shall not exceed 100 kilometers per hour, and motorcycles shall not exceed 80 kilometers per hour. 3. Regulation 3: For roads with 2 lanes in the same direction, the minimum speed for the left lane is 100 kilometers per hour; for roads with 3 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 is inconsistent with the above lane speed regulations, the speed limit indicated by the road signs shall be followed.
