A D endorsement lets you drive a school bus or other vehicles designed to carry 16 or more passengers
A D endorsement is an addition to your driver's license that authorizes you to operate vehicles built to carry 16 or more people. In most states, this means school buses, transit buses, and shuttle vans. Without a D endorsement, driving these vehicles is illegal even if you have a regular driver's license, and you can face fines, license suspension, or criminal charges.
The D endorsement is separate from a commercial driver's license (CDL). Some states require a CDL to drive certain large passenger vehicles; others use the D endorsement for smaller passenger buses. The rules depend on the vehicle's gross vehicle weight rating (GVWR) and seating capacity, which vary by state.
If you drive a school bus, work for a transit authority, or operate a charter or shuttle service, you will need to understand whether your state requires a D endorsement, a CDL, or both. Getting the wrong credential can cost you your job and your driving privileges.
Key Takeaways
- A D endorsement authorizes you to drive vehicles designed to carry 16 or more passengers, typically school buses and transit buses.
- Requirements vary by state: some require a D endorsement, others require a CDL, and some require both depending on the vehicle's weight and capacity.
- You must pass a written knowledge test, a skills test, and a medical examination before receiving a D endorsement.
- Most states require fingerprinting and a background check, and school bus drivers must pass additional safety and child welfare screening.
- Renewal periods and fees differ by state, so check your state's Department of Motor Vehicles website for specific costs and timelines.
D Endorsement vs. CDL: Which one you need
The difference between a D endorsement and a CDL depends on the vehicle's weight and capacity. A commercial driver's license (CDL) is required in all states to operate a Class 8 truck (over 26,001 pounds GVWR) or any vehicle designed to carry 16 or more passengers if that vehicle weighs more than 26,001 pounds. A D endorsement typically covers smaller passenger vehicles—those under that weight threshold—that still carry 16 or more people.
Some states use the D endorsement for all passenger buses regardless of weight. Others require a CDL for any bus carrying passengers for hire, even if it weighs less than 26,001 pounds. A few states have phased out the D endorsement entirely and now require a CDL for all passenger vehicle operation. You must check your specific state's rules before pursuing either credential.
If you are unsure which credential your job requires, ask your employer and your state's Department of Motor Vehicles. Driving with the wrong endorsement or license class is a violation that can result in fines, points on your record, and loss of employment.
Steps to obtain a D endorsement
The process for getting a D endorsement follows a standard sequence in most states, though specific requirements and fees vary. Start by contacting your state's Department of Motor Vehicles to confirm that a D endorsement is what you need and to get the exact requirements for your state.
| Step | What you do | What to expect |
|---|---|---|
| 1. Verify requirements | Contact your state DMV or check their website | Learn whether you need a D endorsement, CDL, or both for your job |
| 2. Pass a medical exam | Visit a certified medical examiner | Eye exam, hearing test, blood pressure check; takes 30 minutes to 1 hour |
| 3. Study the manual | Get your state's passenger vehicle manual from the DMV | Learn rules specific to passenger buses and large vehicles |
| 4. Pass the written test | Take the knowledge test at your DMV | Usually 50 questions; you must pass with a score of 80% or higher |
| 5. Schedule a skills test | Book an appointment for the driving test | Wait time varies; some states have a 2-week to 3-month backlog |
| 6. Pass the skills test | Demonstrate vehicle control in a real bus or approved simulator | Test includes pre-trip inspection, basic controls, and on-road driving |
| 7. Background check (if required) | Submit to fingerprinting and criminal history review | Required for school bus drivers in all states; may be required for transit drivers |
| 8. Receive your endorsement | Pay the fee and receive your updated license | License arrives by mail or is issued on the spot, depending on your state |
The entire process typically takes 4 to 12 weeks, depending on how quickly you schedule tests and how long your state's skills test backlog is. If you are explore for a school bus position, add 2 to 4 weeks for the background check and child welfare clearance.
Medical examination and vision requirements
All states require a medical examination by a certified medical examiner before you can receive a D endorsement. This is not your regular doctor's visit—it must be performed by someone on your state's list of approved examiners, often called a DOT medical examiner or certified medical examiner.
The exam includes vision screening (you must see at least 20/40 in each eye, corrected or uncorrected), hearing tests, blood pressure measurement, and a review of your medical history. You will be asked about conditions like diabetes, heart disease, seizures, and sleep apnea, all of which can disqualify you or require special documentation. The exam costs between $75 and $200, depending on your state and the examiner.
You will receive a medical certificate valid for one to three years. Some states require you to renew it before renewing your D endorsement; others do not. Keep a copy of your medical certificate with you while driving, as law enforcement can ask to see it during a traffic stop.
Written and skills testing for passenger vehicle operation
The written test covers passenger vehicle safety, passenger management, emergency procedures, and vehicle inspection. You will study from your state's passenger vehicle manual, which is free and available online or at your DMV. Most written tests have 50 questions, and you must score at least 80% to pass. You can usually retake the test if you fail, though some states charge a fee for each attempt.
The skills test is a behind-the-wheel driving evaluation in an actual bus or an approved simulator. You will be tested on your ability to perform a pre-trip inspection (checking brakes, lights, mirrors, and tires), basic vehicle control (backing up, turning, stopping smoothly), and on-road driving in various conditions. The test typically lasts 45 minutes to 1 hour and is scored by a state-certified examiner.
Skills test wait times vary widely. In rural areas, you may be able to schedule within a week or two. In urban areas with high demand, the wait can be 2 to 3 months. Some states offer simulator-based testing to reduce wait times. Ask your DMV about current scheduling and whether simulator tests are available in your area.
Background checks and clearances for school bus drivers
If you are explore for a school bus driver position, your state will require a background check and child welfare clearance in addition to the standard D endorsement requirements. This is a federal requirement under the School Bus Driver Qualification Standards, and all 50 states enforce it.
The background check includes fingerprinting, a criminal history review, and a check of the sex offender registry. You will also be screened against the National Child Abuse and Neglect Data Bank and, in some states, the Family Violence Registry. If you have a conviction for certain crimes—including felonies, crimes against children, and drug offenses—you will be permanently disqualified from driving a school bus.
Even misdemeanors can delay or prevent your clearance. The background check process takes 2 to 4 weeks in most states. Some states conduct the check before you take the skills test; others conduct it after you pass. Ask your school district or the state's Department of Education which agency handles the clearance and what the timeline is.
D endorsement renewal and maintaining your credential
D endorsement renewal periods and fees vary by state. Most states require renewal every 4 to 8 years, aligned with your regular driver's license renewal. Some states require you to retake the written test at renewal; others do not. Your medical certificate must also be current, and in some states you must renew it before your D endorsement expires.
If you let your D endorsement expire, you cannot legally drive a passenger vehicle until you renew it. Renewal is usually simpler than the initial process—you may only need to renew your medical certificate and pay a fee—but the exact process depends on your state. Check your state's DMV website or call ahead to confirm what you need to bring and whether you must retake any tests.
If you move to a different state, you will need to transfer your D endorsement to your new state's license. This typically requires passing that state's written test and skills test, even if you already hold a valid D endorsement elsewhere. Some states have reciprocity agreements that waive the skills test, but most do not. Contact your new state's DMV before you move to understand the transfer process.
Frequently Asked Questions
Do I need a D endorsement if I drive a van with 15 passengers?
No. A D endorsement is required only for vehicles designed to carry 16 or more passengers. A 15-passenger van does not require a D endorsement or CDL. However, if the van is registered as a commercial vehicle or used for hire, your state may have other licensing requirements. Check with your state's DMV to be certain.
Can I get a D endorsement if I have a DUI or reckless driving conviction?
It depends on how recent the conviction is and your state's rules. Most states will not issue a D endorsement to someone with a DUI or reckless driving conviction within the past 3 to 5 years. School bus driver positions have stricter rules and may disqualify you permanently. Contact your state's DMV with your specific conviction details to learn whether you are disqualified.
What happens if I drive a bus without a D endorsement?
You can be cited for operating a vehicle without the required endorsement, which is typically a misdemeanor. Penalties include fines (usually $500 to $1,000), points on your driving record, and possible license suspension. Your employer can also face fines. If you cause an accident while driving without the proper endorsement, your insurance may deny your claim.
How much does a D endorsement cost?
Fees vary by state, ranging from $25 to $150 for the endorsement itself. Add $75 to $200 for the medical exam and $0 to $50 per test attempt for the written test. Skills test fees are usually included in your DMV testing fee or charged separately at $50 to $100. School bus driver background checks are sometimes free and sometimes cost $25 to $75. Contact your state's DMV for exact pricing.
Can I take the D endorsement skills test in a different vehicle than the one I will drive for work?
Yes, in most states. You can take the test in any bus or approved simulator that meets your state's specifications. However, the vehicle must be the same class or type as the one you will drive for work. If you will drive a full-size school bus, you must test in a full-size bus, not a smaller shuttle van. Ask your DMV which vehicles are approved for testing in your area.
