Can I drive Class A or Class B vehicles with a Class C CDL?

CDL classes are not nested upward — Class C does not include Class A or B privileges, only the smaller Class C set. If your career path moves toward bigger vehicles, you'll need to take a separate ELDT and skills test for the higher class. Class C drivers most commonly upgrade to Class B for larger transit buses or to Class A for tractor-trailer work.

The upgrade requires its own ELDT theory and behind-the-wheel training, which we offer as separate courses in our catalog. The non-nested structure reflects the genuine skill differences between vehicle classes — operating a tractor-trailer requires capabilities a small shuttle driver hasn't been trained on, regardless of how skilled the shuttle driver may be in their own vehicle. The upgrade pathway exists specifically to bridge those skill gaps before authorizing the larger vehicle operation.

Drivers planning a long-term commercial driving career should think carefully about whether starting with Class C makes sense versus starting with Class B or Class A directly. Class C is the right starting point for drivers committed to passenger or hazmat operations specifically; drivers uncertain about their long-term direction may be better served starting with a larger class that offers more downstream optionality. The training investment compounds across the career, so the initial class choice shapes the trajectory more than drivers sometimes realize at the start.
