If you drive a commercial vehicle designed to carry 16 or more passengers — including the driver — you need more than a standard Commercial Driver's License (CDL). You need a passenger (P) endorsement. Where you get it, what it takes to qualify, and how long the process runs all depend on your state, your existing license status, and your driving record.
The P endorsement is a federally required add-on to a CDL that authorizes drivers to operate vehicles built to transport 16 or more people. This includes buses, charter coaches, large shuttle vehicles, and certain transit vehicles. It is governed by federal regulations set by the Federal Motor Carrier Safety Administration (FMCSA), but administered at the state level through each state's motor vehicle or licensing agency.
Without this endorsement, a CDL holder cannot legally operate those vehicles in commercial service — regardless of experience or other credentials.
The short answer: your state's DMV or equivalent licensing agency.
Because CDL endorsements are issued at the state level, the passenger endorsement is applied to your CDL through the same agency that issued your commercial license. That's typically:
The agency name varies by state. What doesn't vary: you apply where your CDL was issued, and that state's licensing office is the only entity that can add the endorsement to your credential.
To earn the P endorsement, drivers generally must clear two testing hurdles — and in some states, additional steps.
Every state requires a written knowledge test covering passenger-specific topics, including:
This test is drawn from the FMCSA's CDL standards, which means the subject matter is consistent across states — but passing scores, number of questions, and retake policies differ by state.
After passing the knowledge portion, applicants must pass a skills (road) test conducted in a representative vehicle — meaning a bus or passenger vehicle of the type they intend to operate. The test covers:
Some states allow third-party examiners — including certain employers or training programs — to administer the skills test. Others require applicants to test directly with the state licensing agency.
| Requirement | Notes |
|---|---|
| Proof of CDL (Class A, B, or C) | P endorsement requires a valid CDL as the base credential |
| Medical certificate | CDL holders must maintain a valid FMCSA medical certificate; some states require updated documentation at endorsement time |
| Background check or clearance | Some states — and many employers — require additional screening for drivers carrying passengers |
| Application fee | Endorsement fees vary significantly by state and license class |
| Hazmat combination | Drivers needing the school bus (S) endorsement must hold the P endorsement first |
The P endorsement can be added to a Class A, Class B, or Class C CDL, depending on the vehicle being operated:
The vehicle you'll operate determines which CDL class you need — and that class must be in place before the endorsement can be added.
Most states offer knowledge testing at any regional DMV or licensing office — not just the one that issued your original CDL. Skills testing locations are more limited, since they require space for a full-size vehicle and certified examiners.
Some states contract with third-party testers (trucking schools, transit agencies, or employer-affiliated testing sites), which can expand where and when you can schedule the skills portion. Whether third-party testing is available — and which providers are approved — varies by state.
Once you pass both tests and pay any applicable fees, the P endorsement is reflected on your CDL. Some states issue a new physical license immediately; others update your record digitally and mail a new credential. Processing timelines vary.
Endorsements are renewed on the same cycle as your CDL — typically every four to eight years depending on the state. Retesting requirements at renewal also vary.
How straightforward this process is for any individual driver depends on several factors that no general overview can fully account for:
The federal framework is consistent. The state-level execution is not.
