”Truck” is a vague term that’s commonly applied to every type of truck, whether it’s a smaller pickup truck or a large 18 wheeler truck. But we all know that a city garbage truck and the Chevy truck you use for weekend fishing are not the same truck. You can’t compare a Freightliner Cascadia to a Toyota Tacoma, which is why there are truck classes to more easily categorize all “trucks” you see on a daily basis.
There are eight (technically nine, but we’ll get to that later) classes of trucks that range from weight to duty classifications. These classes do matter, not only because they determine what parts you’ll need for your vehicle, but also because they can also affect part warranties, what you’re allowed to drive as a truck driver, and more.
