What Is a Class C CDL?
A Class C CDL is for vehicles that do not meet the definition of Class A or Class B and are designed to transport 16 or more passengers including the driver, or to transport hazardous materials requiring placards. Class C vehicles are typically lighter vehicles, but the CDL classification depends on passenger capacity, hazardous material requirements, and vehicle weight ratings.

What Vehicles Can You Drive with a Class C CDL?
One of the first questions most applicants have is: what can I actually drive with a Class C CDL? Here's a breakdown of the most common commercial vehicle types and job categories it covers:
Shuttle vans and buses running between airports, hotels, rental car facilities, and parking lots — any route carrying 16 or more passengers.
Mid-size passenger vans used by religious organizations, nonprofits, and community groups to transport members.
High-roof multi-passenger vans used by adult day programs and senior living facilities for daily transportation needs.
Wheelchair-accessible vans and ADA-compliant vehicles used for non-emergency patient transport and disability services.
Cargo vans or box trucks under 26,000 lbs GVWR carrying placardable quantities of chemicals, compressed gas cylinders, or regulated medical waste.
Endorsements You'll Need for a Class C CDL
Here's something many first-time applicants don't realize: A Class C CDL is designed for specific commercial operations, mainly vehicles carrying passengers or transporting placarded hazardous materials. To legally operate most Class C vehicles for hire, you'll need to pass additional knowledge tests for one or both of these endorsements:
If you plan to operate a commercial vehicle designed to transport 16 or more passengers including the driver, you must obtain the Passenger (P) endorsement.Expect questions on safe passenger boarding and alighting, on-board emergency procedures, railroad and highway-rail grade crossing rules, and proper evacuation drills.
If you'll be hauling materials that legally require placards — such as flammable liquids, compressed gases, or regulated medical waste — you must pass the HazMat endorsement test. In addition to mastering the HazMat regulations (loading, segregation, and placarding tables), you'll also need to clear a TSA security threat assessment, which includes a federal fingerprint-based background check.
Do Class C CDL Requirements Vary by State?
The federal definition of a Class C CDL — including GVWR thresholds and passenger counts — is set by the FMCSA and applies nationwide. However, each state's DMV sets its own test format, fee schedule, CLP rules, and retesting waiting periods.
High-volume states like California, Texas, Florida, New York, and Illinois each have their own approach to the knowledge test, including different question pools and varying CLP validity periods.

Class C CDL — Frequently Asked Questions
Q: Do I need to pass the Air Brakes test for a Class C CDL?
A: In most cases, no. Whether an Air Brakes knowledge test is required depends on whether the vehicle is equipped with air brakes, not the CDL class alone. That said, If you operate a CDL vehicle equipped with air brakes, you must pass the Air Brakes knowledge test and complete the required air brake testing requirements to remove the L restriction.
Q: Can I drive a school bus with a Class C CDL?
A: Yes, for small school buses designed to carry 16 or more people. However, you'll need more than just the base Class C CDL — you must also hold both the Passenger (P) endorsement and the School Bus (S) endorsement. Both are required without exception.
Q: Can a Class C CDL holder transport hazardous materials?
A: Yes — but only with a valid HazMat (H) endorsement. Transporting placardable hazardous materials in a lighter-weight vehicle is actually one of the two primary reasons drivers need a Class C CDL in the first place.
Q: What's the difference between a Class C CDL and a regular driver's license?
A: A standard non-commercial driver's license (also called a Class C license in some states) only allows you to drive personal vehicles under 26,000 lbs for private use — no carrying 16+ passengers for hire and no hauling regulated hazardous materials. A Class C CDL, by contrast, is a federally regulated commercial credential governed by FMCSA rules, required for professional, for-hire operations.
Q: What's the difference between a Class C CDL and a Class B CDL?
A: The key difference is vehicle weight. Class B CDL covers single vehicles with a GVWR of 26,001 pounds or more, or such vehicles towing a vehicle 10,000 pounds GVWR or less. Additional endorsements may be required depending on passengers, HazMat, or other operations. Class C CDL applies to vehicles that do not qualify as Class A or Class B but require a CDL because they carry 16 or more passengers including the driver or transport placarded hazardous materials.
