Truck classes help shippers, carriers, and warehouses understand what a vehicle can legally haul. They’re based on Gross Vehicle Weight Rating (GVWR)—basically how heavy the truck can be when fully loaded.
- Light‑Duty — Class 1–3
- Everyday pickups and vans. Ideal for small deliveries, service work, and lighter commercial loads.
- Medium‑Duty — Class 4–6
- Box trucks, larger service trucks, and local delivery vehicles. Common in regional freight and warehouse distribution.
- Heavy‑Duty — Class 7–8
- The big rigs. Semi‑trucks, tractor‑trailers, and specialized haulers. Built for long‑haul freight and maximum payload.
Understanding these classes helps you match the right truck to the right job—avoiding overweight fines, improving efficiency, and keeping your freight moving smoothly.
