What is considered a heavy-duty truck?

Driving down the roads of Springfield, MA, Wilbraham, MA, Chicopee, MA, Holyoke, MA, and Hampden County, MA, you have likely seen many heavy-duty trucks driving alongside you. Any vehicle that weighs more than 26,001 pounds is considered a heavy-duty truck. Some examples of heavy-duty trucks include mobile cranes, city transit buses, tractors designed to pull trailers, refuse trucks, cement mixers, and dry vans. Heavy-duty trucks are generally divided into three categories:

  • Class 7: 26,001 to 33,000 pounds (ex. garbage collection vehicles, livestock transports)
  • Class 8: 33,001 pounds or heavier (ex. 18-wheelers, sleeper cabs, dump trucks, tractor-trailers)
  • Class 9: Vehicles that weigh more than 60,000 pounds (super heavy/special duty truck) 

Many heavy-duty trucks have large engines that run on diesel as well as have enhanced transmissions because these trucks are designed to tow large loads. Heavy-duty trucks are also seen on job sites, where they are required to carry large construction materials. They have a towing capacity of over 20,000 pounds and offer payload capacities of over 6,500 pounds - enough to haul pretty much anything that can fit in the truck's bed.

Light Duty Truck Repair in Springfield, MA

The United States federal regulations define light-duty trucks as trucks and vehicles that have a gross vehicle weight up to 8,500 pounds and payload capacities up to 4,000 pounds. These vehicles can include vans, pickup trucks, minivans, and sport utility vehicles (SUV). The government set this vehicle classification for the regulation of fuel economy. These vehicles are typically used for utility rather than personal use, so these vehicles have lower fuel economy standards. 

This regulation started in the 1970s when fuel economy regulations were starting to form and the United States government determined that trucks should not be held to the same standards as passenger cars. As the number of trucks sold increased, the initial regulation for trucks was now split to light-duty trucks and heavy-duty trucks. 

Here are some of the best-selling light-duty trucks today:

  • Toyota Tundra: The Tundra is available in different cab configurations, but all feature Toyota’s V8 engine that could tow up to 10,200 pounds.
