In this article, we will delve into what defines these classes of trucks, their characteristics, and their applications.
What Are Class 7 and 8 Trucks?
Class 7 and 8 trucks are categorized based on their Gross Vehicle Weight Rating (GVWR), which is a crucial factor in determining their capabilities and uses. Here’s a breakdown of each class:
- Class 7 Trucks: These trucks have a GVWR ranging from 26,001 to 33,000 pounds. They are often used for local delivery, construction, and other applications that require a balance of power and maneuverability. Common examples include larger box trucks and some types of buses.
- Class 8 Trucks: This class includes trucks with a GVWR of over 33,000 pounds. Class 8 trucks are typically used for long-haul transportation and heavy-duty applications. They include tractor-trailers, dump trucks, and other vehicles designed for significant payloads. These trucks are essential for freight transport across the country.

Both classes of trucks share some common features, but they also have distinct characteristics that set them apart:
- Engine Power: Class 8 trucks generally have more powerful engines compared to Class 7 trucks, allowing them to handle heavier loads and longer distances.
- Size and Dimensions: Class 8 trucks are larger and often come with more advanced technology for navigation and safety, making them suitable for highway driving.
- Fuel Efficiency: While both classes are designed for efficiency, Class 8 trucks are increasingly incorporating fuel-saving technologies to reduce operational costs.
