You need a Commercial Driver's License (CDL) with a Passenger (P) endorsement to drive a bus that carries passengers for money

A regular driver's license does not permit you to drive a bus, even if you own it or drive it only occasionally. The Passenger endorsement is the specific add-on to a CDL that authorizes you to transport people. If you drive a bus without the correct endorsement, you can be cited, fined, and have your license suspended — even if you have a CDL for other reasons.

The endorsement requirement applies whether you drive a school bus, a tour bus, a shuttle, or any vehicle designed to carry more than a certain number of passengers. That threshold varies by state, but most states set it at 16 or more passengers (including the driver). Some states count differently, so check your state's Department of Motor Vehicles (DMV) website for the exact passenger count that triggers the requirement.

Key Takeaways

  • A Passenger (P) endorsement on a Commercial Driver's License is required to drive a bus that carries passengers for compensation.
  • You must first hold a valid CDL before you can add the Passenger endorsement; you cannot get the endorsement on a regular driver's license.
  • The written test for the Passenger endorsement covers passenger safety, loading procedures, emergency equipment, and how to handle disruptive passengers.
  • Most states require a background check and a medical examination (DOT physical) before issuing a CDL with Passenger endorsement.
  • School bus drivers in most states need an additional School Bus (S) endorsement on top of the Passenger endorsement.

How to get a CDL first, if you don't have one

Before you can add a Passenger endorsement, you must hold a valid Commercial Driver's License. If you do not have a CDL yet, you will need to pass a written knowledge test and a skills test (driving test) for the class of vehicle you plan to drive. Most bus drivers need a Class B CDL, which covers vehicles weighing more than 26,001 pounds but does not require towing a trailer.

To start, visit your state's DMV office and ask for the CDL handbook. Study the general knowledge section and the section for your vehicle class. You will then take the written test at the DMV. If you pass, you schedule a driving test with an examiner, usually within a few weeks. The examiner will watch you perform a pre-trip inspection, basic vehicle control maneuvers, and on-road driving.

Many states allow you to take the written test and driving test on the same day if you pass the written portion first. Once you pass both, you receive a CDL. At that point, you can add endorsements.

The Passenger endorsement written test and what it covers

After you have your CDL, you request the Passenger endorsement by taking an additional written test at your DMV. This test focuses on passenger safety and bus operation. You will answer questions about loading and unloading passengers, securing wheelchairs and mobility devices, handling medical emergencies, managing disruptive or intoxicated passengers, and operating emergency exits and equipment.

The test also covers pre-trip inspection items specific to passenger vehicles — things like checking that all seats are find, that emergency exits are clearly marked and functional, and that communication systems work. You will study these topics in the Passenger section of the CDL handbook, which your state's DMV provides.

Most states require you to score at least 80 percent on the written test to pass. If you fail, you can retake it, usually after a waiting period of a few days. There is no driving test for the Passenger endorsement itself — the endorsement is added to your existing CDL once you pass the written portion.

Medical examination and background check requirements

Before your state issues a CDL with a Passenger endorsement, you must pass a Department of Transportation (DOT) physical examination. This is a medical evaluation performed by a certified medical examiner to confirm you are physically able to operate a commercial vehicle safely. The exam checks your vision, hearing, blood pressure, and ability to operate the controls. You must be at least 21 years old to hold a CDL with Passenger endorsement (some states allow 18-year-olds with restrictions).

You will also undergo a background check, which typically includes a review of your driving record and criminal history. Certain convictions or violations can disqualify you from holding a CDL. Your state's DMV can tell you which offenses are disqualifying. If you have questions about your specific record, contact your local DMV office before you begin the process.

School bus drivers need an additional endorsement

If you plan to drive a school bus, you need both the Passenger (P) endorsement and the School Bus (S) endorsement. The School Bus endorsement has its own written test that covers topics specific to transporting children — such as how to manage student behavior, how to operate the stop-arm and warning lights, and how to evacuate students in an emergency.

School bus drivers also must pass a fingerprint-based background check and a criminal history check that is more thorough than the standard CDL background check. Many states require school bus drivers to complete additional training before they can begin work. Check your state's Department of Education website for school bus-specific requirements, as these vary significantly by state.

Renewing and maintaining your Passenger endorsement

Your CDL with Passenger endorsement must be renewed according to your state's schedule, typically every four to eight years. When you renew, you will need to pass a new DOT physical and may need to retake the Passenger endorsement written test, depending on your state's rules. Some states allow you to renew by mail if you have no violations, while others require an in-person visit.

If your CDL is suspended or revoked, your Passenger endorsement is suspended or revoked along with it. Serious violations — such as driving under the influence, reckless driving, or at-fault accidents — can result in loss of your CDL and endorsements. Keep your driving record clean and follow all traffic laws to maintain your endorsement.

Frequently Asked Questions

Can I drive a bus with just a regular driver's license if the bus is empty?

No. The requirement for a CDL with Passenger endorsement applies based on the vehicle's design capacity, not whether passengers are actually on board. If the bus is built to carry more than the threshold number of passengers (usually 16), you need the endorsement to operate it, even if it is empty.

Do I need a Passenger endorsement to drive a shuttle for my employer if I am not paid extra to drive?

Yes. The endorsement is required whenever you operate a bus designed for passengers, regardless of whether you receive separate compensation for driving. Your job title or pay structure does not change the licensing requirement.

How long does it take to get a Passenger endorsement after I have my CDL?

The written test itself takes about 30 minutes to an hour. You can often take it the same day you request it at your DMV, so the endorsement can be added to your license within hours or days. The longest part is usually scheduling your appointment at the DMV.

What happens if I let my CDL expire while I have a Passenger endorsement?

Your Passenger endorsement expires along with your CDL. You cannot drive a bus once your CDL is expired. To restore it, you must renew your CDL and may need to retake the Passenger endorsement test, depending on how long it has been expired and your state's rules.

Can I get a Passenger endorsement if I have a DUI on my record?

A DUI conviction may disqualify you from holding a CDL, depending on when it occurred and your state's rules. Some states have a waiting period; others have permanent disqualifications. Contact your state's DMV to review your specific situation before you begin the process.
