What CDL Do I Need to Drive a Passenger Bus?
Buses are the one case where seats, not weight, bring the CDL rules in. A sixteen seat shuttle that weighs less than a pickup and trailer still needs a commercial license.
Any vehicle built to carry 16 or more passengers including the driver needs a CDL with the P endorsement. Over 26,001 pounds that is a Class B; under it, a Class C.
Endorsement required: P What the letters mean
Why a passenger bus falls where it does
The federal definitions count passenger capacity as well as weight. A vehicle designed to transport 16 or more passengers including the driver is a commercial motor vehicle, and the P endorsement is required to carry passengers in it.
Which class you need then depends on the rating. A full size transit bus or motorcoach rated over 26,001 pounds is Class B with P. A smaller shuttle or cutaway van under that rating, seating 16 or more, is Class C with P.
The numbers that decide it
The federal classes are defined on the manufacturer's ratings, not on what is loaded today.
- Transit bus or motorcoach, over 26,001 lbs, 16 or more passengers
- Class B CDL with the P endorsement.
- Shuttle or cutaway van under 26,001 lbs, 16 or more passengers
- Class C CDL with the P endorsement.
- Van seating 15 or fewer including the driver
- No CDL for capacity or weight. The classic fifteen passenger van.
- School bus of any size
- Class B or C with both P and S.
Air brakes
Full size buses have air brakes, so the restriction has to come off. Smaller cutaway shuttles usually have hydraulic brakes, and the air brake test does not apply to them.
Air brakes is not an endorsement. It is a restriction that stays on your license until you pass the air brake knowledge test, and it bars you from every air braked vehicle while it is there.
When the answer is different
The P endorsement carries a skills test as well as a knowledge test, and it is taken in a vehicle of the type you intend to drive. Passing it in a small bus can leave a restriction limiting you to that size, so test in the vehicle you actually want to drive.
A first time P endorsement also triggers the federal Entry-Level Driver Training requirement through a registered provider.
What people get wrong
- Counting only the seats behind the driver. The threshold is 16 including the driver, so 15 passenger seats plus the driver is the line.
- Taking the P skills test in the smallest available bus and inheriting a restriction.
- Assuming a light shuttle cannot need a CDL. Capacity triggers it on its own.
Not sure this is what you will end up driving?
The CDL Selector asks a few yes or no questions and tells you the class and the endorsements your plans actually need, which is worth doing before you pay for a knowledge test.

Questions people ask about driving a passenger bus
How many passengers before I need a CDL?
Sixteen or more including the driver, based on how the vehicle is designed rather than how many people are aboard on a given trip.
Do I need a Class B or Class C for a bus?
Class B if the bus is rated 26,001 pounds or more, Class C if it is under that and still seats 16 or more including the driver. Both need the P endorsement.
Is there a skills test for the passenger endorsement?
Yes. Unlike most endorsements, P has a skills test as well as a knowledge test, and it is taken in a vehicle of the type you intend to drive. Ohio Bureau of Motor Vehicles can tell you what vehicle it will accept.
Do I need a CDL for a 15 passenger van?
Not for capacity or weight, since the threshold is 16 including the driver. Employers and insurers often impose their own requirements anyway.
