What Industries Have Heavy Duty Truck Fleets?
In addition to for-hire fleets with tractor-trailers, there are dozens of other industries with large heavy duty truck fleets. For this reason, if you want to reach these fleets, it’s important to understand all the industries with heavy duty trucks.
See our charts of the industries below.
What's a Heavy Duty Fleet Vehicle?
We define heavy duty vehicles as Class 7 and Class 8.
Class 8
Includes vehicles with a Gross Vehicle Weight Rating (GVWR) of 33,001 lbs or more. This includes the tractor-trailers (also called semi-trucks and 18-wheelers) that are the vehicles most people are thinking of when they search for heavy duty fleets. Class 8 also includes cement and dump trucks because of their heavy loads.
Class 7
Includes trucks and buses with a GVWR of 26,001 to 33,000 lbs, such as vocational trucks, refuse trucks, fuel trucks, bucket trucks, furniture trucks and city transit buses.
Depending on the vehicle size, fire trucks, fuel trucks and buses can be Class 7 or Class 8.
The data on this page focuses on non-passenger vehicles.
For-Hire Trucking Industry
The biggest heavy duty industry is for-hire trucking. These are trucking companies that are hired by other businesses to transport goods. Example fleets you may recognize on the roads: UPS, FedEx, J.B. Hunt, Knight-Swift, Schneider.
If you use SIC and NAICS to identify industries, these codes include for-hire trucking companies:
- SIC 4212 – Local Trucking Without Storage
- SIC 4213 – Trucking Except Local
- SIC 4214 – Local Trucking With Storage
- SIC 4731 – Arrangement of Transportation-Freight
- SIC 4789 – Transportation Services NEC
- NAICS 484110 – General Freight Trucking, Local
- NAICS 484121 – General Freight Trucking, Long-Distance, Truckload
- NAICS 484122 – General Freight Trucking, Long-Distance, Less Than Truckload
Private Fleet Industries
Other than for-hire fleets, all remaining industries with heavy duty vehicles are private fleets.
Companies maintain private fleets to carry their own goods, such as a grocery store chain that distributes products to its own stores. Private fleets also use vehicles to deliver services for the company’s customers, or for company operations. Government agencies have private fleets to carry out operations and services for their residents. Examples:
- Waste & Refuse: WM, Republic Services
- Landscaping: TruGreen, BrightView
- Utilities: Exelon, Pacific Gas & Electric
- Government: Chicago Dept. of Transportation, State of Minnesota Fleet Services
The primary business of these companies and government agencies is not trucking. So these fleets will be classified under many industries. For this reason, if you want to reach heavy duty fleets, it’s important to understand all the industries with heavy duty trucks.
