What Is Considered a Heavy-Duty Truck?

Any vehicle with a gross vehicle weight rating (GVWR) over 26,001 pounds is considered heavy-duty. These trucks are built for demanding work, from long-distance freight to heavy hauling and construction site support. Here’s how heavy-duty trucks are classified:

• Class 7: 26,001 to 33,000 lbs (e.g., refuse trucks, livestock transporters)
• Class 8: 33,001 lbs and above (e.g., 18-wheelers, dump trucks, tractor-trailers)
• Class 9: Over 60,000 lbs (specialty heavy trucks like mobile cranes)

Most of these vehicles feature diesel engines, reinforced transmissions, and payload capacities that exceed 6,500 pounds, making proper service critical for performance and safety.
