CDL Class C (CDL-C).
Commercial Driver's License Class C — for single vehicles under 26,001 lbs GVWR transporting 16+ passengers or placardable hazmat.
What it is
CDL Class C is the smallest commercial license tier. It is required for single vehicles under 26,001 lbs GVWR that fall into one of two regulatory categories: (1) vehicles designed to transport 16 or more passengers including the driver, or (2) vehicles transporting hazardous materials in placardable quantities, regardless of vehicle weight rating.
Most CDL-C operations are passenger-related — shuttle vans, hotel airport shuttles, small charter operations. Some hazmat operations also fall under CDL-C: fuel delivery in smaller tanks, certain medical and scientific transport, and specialty couriers carrying placardable quantities below the GVWR threshold for Class B. CDL-C still requires the federal DOT medical examination and ELDT for the relevant endorsements (P, S, H), but the skills test is conducted on a smaller vehicle than Class A or B. The same hazmat TSA Threat Assessment process applies for the H endorsement attached to CDL-C.
Why it matters for trucking finance
CDL-C is not directly relevant to most freight owner-operators — the freight market for sub-26,001-lb commercial vehicles is dominated by drivers who don't need a CDL at all (Class 3–6 box trucks under the GVWR threshold operate on standard driver's licenses).
Some delivery operators — medical, scientific, hazmat-rated specialty couriers, small-tank fuel delivery — operate under CDL-C and live in a niche commercial-vehicle financing segment with different lender panels than Class 8 trucking. Insurance for CDL-C operations is structured around the specific use case: passenger shuttle insurance and hazmat courier insurance are entirely different products with different rating bases, different limits, and different carrier panels. For operators transitioning between CDL-C and higher tiers, the credentialing ladder is additive.
