Semi-Trucks vs. Trucks: What's the Difference?

28 Feb.,2024

 

What is the Difference Between a Semi-Truck and a Truck?

You likely have heard many different names used for the giant vehicles that haul goods and cargo on the highway — semi-truck, tractor-trailer, big rig, 18-wheeler, or simply truck. But do each of these names refer to different types of vehicles? Are there any differences between a truck, semi-truck, and 18-wheeler?

Semi-Truck, Truck, 18-Wheeler: What’s the Difference?

Depending on the context, the term “truck” may refer to a wide range of commercial vehicles, including box trucks, tractor-trailers, semi-trucks and  18-wheelers in Utah. These specific terms typically refer to a truck’s body type, wheels, and other defining characteristics.

A semi-truck has two parts: a trailer, which carries cargo, and a tractor, which contains the engine. Notably, a semi-truck’s tractor can detach from its trailer, and semi-trucks often travel without trailers.

The terms 18-wheeler and tractor-trailer simply refer to a semi-truck and its trailer. Tractor-trailers are sometimes called 18-wheelers due to the total number of wheels on the tractor and trailer.

Are All Semi-Trucks Commercial Motor Vehicles?

A commercial vehicle transports goods or passengers for a profit. Semi-trucks often fall under this definition. A vehicle could also be considered a commercial vehicle if it meets a certain weight threshold. A semi-truck will certainly qualify as a commercial motor vehicle when combined with a trailer.

Different Types of Trailers for Semi-Trucks

Semi-trucks have various types of trailers, each designed for a specific job or to haul a particular kind of cargo. These include:

  • Flatbed trailers
  • Refrigerated trailers
  • Lowboy trailers
  • Conestoga trailers
  • Dry van trailers
  • Logging trailers
  • Tipper trailers
  • Single/double drop trailers
  • Removable gooseneck trailers
  • Liquid or gas tankers
  • Car carriers

What to Do After a Semi-Truck Accident

The things you do after a truck accident can impact your health and ability to recover compensation. If possible, you should:

  • Call 911.
  • Get the truck driver’s driver’s license number, employer name, and insurance information.
  • Take photos and video of the crash scene.
  • Go to the hospital or see a doctor to evaluate your injuries.
  • Keep copies of medical bills and receipts for accident-related expenses.
  • Retain your pay stubs and tax returns if you missed work while recovering from your injuries.
  • Talk to a truck accident attorney to learn your legal options.
