What is the load limit for two-axle vehicles on highways?
3 Answers
Two-axle vehicles are temporarily limited to 18 tons, 6×4 vehicles are limited to 49 tons, and 6×2 vehicles are limited to 46 tons, with unified national standards. Below is more information about two-axle vehicles: 1. Axle: An axle is a vehicle bridge, and a two-axle vehicle has two bridges. 2. Two-axle truck: A truck with one front axle and one rear axle is called a two-axle truck. 3. Three-axle truck: A truck with one front axle and two rear axles, or two front axles and one rear axle is called a three-axle truck. 4. Drive shaft: It is used to transmit driving force from the engine to the drive wheels. 5. Other introductions: Non-driven axles are called axles, while driven axles are called bridges. Some three-axle vehicles have one axle in the front and one bridge and one axle in the rear, marked as (6×2). Some three-axle military off-road vehicles are all-wheel drive, marked as (6×6). Light trucks are generally (4×2), while heavy trucks are generally (6×4).
I've been in freight transportation for almost twenty years, driving two-axle trucks on highways with a load limit of 18 tons. From a novice to a veteran, I've seen too much: once a friend overloaded to 22 tons, the truck's axle was deformed by the weight, and it almost overturned on a sharp highway curve—fortunately, nothing happened. Overloading not only results in fines but also threatens everyone's safety and can easily damage bridge structures. I always weigh my load with a scale before heading out, keeping it under 18 tons. This way, there's less tire wear and better fuel efficiency. Remember, proper loading extends the truck's lifespan—don't get greedy at critical moments to avoid delays and dangers. I also teach these principles to my apprentices, helping them develop good habits before accidents happen. Safe driving is what our families pray for!
I've worked in an auto repair shop for over a decade, regularly servicing two-axle truck customers. The highway weight limit is typically set at 18 tons, and this isn't arbitrary: each axle can bear a maximum of 10 tons—exceeding this affects the suspension and braking systems. During repairs, we often see overloaded vehicles with deformed chassis components or even burst tires. I advise owners to manually check cargo weight before each trip or visit a professional weighbridge. Don't underestimate these habits—they reduce breakdowns and extend vehicle life. Long-term, adhering to weight limits saves repair costs and prevents roadside breakdowns. Well-maintained equipment ensures smoother journeys!
