All trucks, from a Chevy S-10, to the largest, heavy-duty trucks on the road, are classified into categories. Trucks are categorized by weight into classifications 1-9, and each grade comes with its own set of regulations and license requirements. Here’s a quick guide, from Harold's Used Auto Parts Inc in Philadelphia.

Class 1
Light truck 0 - 6,000 pounds

Class 2
Light truck 6,001 - 10,000 pounds

Class 3
Light truck 10,001 - 14,000 pounds

Class 4
Medium truck 14,001 - 16,000 pounds

Class 5
Medium truck 16,001 - 19,500 pounds

Class 6
Medium truck 19,501 - 26,000 pounds

Class 7
Heavy truck 26,001 - 33,000 pounds

Class 8
Heavy truck 33,001 pounds

Class 9
Super-heavy / special duty truck 33,001 pounds

While any truck can be a commercial truck, a special license isn’t required until a truck exceeds 26,000 pounds, loaded. Classes 7 and 8 require a CDL, and class 9 is typically reserved for large specialty trucks, for use in mining and logging operations. Trucks falling in classes 1-6 don’t require special permits; just a normal driver’s license.
