What are the general length and width of large vehicles?

According to the unified requirements of the seven national ministries and commissions, highway overload control has been implemented. As per relevant regulations, the total weight of a six-axle truck and its cargo must not exceed 55 tons. The length limit for general trucks and semi-trailer tractors is 12 meters, the width limit is 2.5 meters, and the height limit is 4 meters. Here are additional details: 1. Dimensions of a 2.5-ton truck: Length 4.2 meters × Width 1.9 meters × Height 1.8 meters (distance from the ground to the truck bed is 1.1 meters), actual load capacity: 3 tons/12 cubic meters; 2. Dimensions of a 3.5-ton truck: Length 6.2 meters × Width 2.0 meters × Height 2 meters, actual load capacity: 5 tons/30 cubic meters (distance from the ground to the truck bed is 1.1 meters).
I've been driving long-haul trucks for over a decade. The typical cargo trucks I operate are usually between 10 to 12 meters in length and about 2.5 meters in width. These dimensions are quite reasonable, ensuring sufficient cargo capacity without occupying too much road space. On highways, this length and width fit well with standard lane sizes, though you need to take wide turns to avoid scraping the roadside barriers. The width is kept under 2.5 meters primarily for safety reasons - anything wider would make urban navigation difficult, especially in narrow corners of older streets. I've learned this the hard way with scratched fenders. Longer vehicles like articulated trailers can reach 18 meters, but they require special permits, and exceeding limits results in heavy fines. Buses share similar dimensions, requiring dedicated parking spots - a real headache when unavailable. In daily maintenance, size affects fuel efficiency too; increased length means greater wind resistance, though it does make chassis repairs somewhat easier. Ultimately, dimensions are crucial when driving large vehicles, which is why I always double-check before each trip to ensure journey safety.
