A bus driver license is a commercial license that lets you operate a vehicle carrying passengers for money
A Class B Commercial Driver License (CDL) is what you need to drive a bus. It is different from a regular passenger car license because buses are larger, carry more people, and require different training and testing. Most states call this a Class B CDL, though a few use different names.
Getting a bus driver license takes longer than getting a regular license because you have to pass written tests on bus-specific rules, pass a skills test in an actual bus, and often complete formal training. You will also need a medical certificate proving you are physically able to drive safely. The whole process usually takes several weeks to a few months, depending on how quickly you complete training and testing.
This license is required whether you drive a city transit bus, a school bus, a tour bus, or any other bus that carries passengers for payment. If you drive a school bus, your state may have additional requirements beyond the CDL.
Key Takeaways
- You need a Class B Commercial Driver License to drive any bus that carries passengers for money, and you must be at least 18 years old (21 in some states for interstate driving).
- Before you can take the CDL test, you must pass a Department of Transportation medical exam and get a medical certificate proving you are fit to drive.
- You will take a written test on bus-specific rules, a pre-trip inspection test, and a road test in an actual bus, all administered by your state's DMV.
- Many states require or strongly recommend formal bus driver training through a CDL training school before you test, which can take two to six weeks.
- School bus drivers may need additional background checks, fingerprinting, and state-specific endorsements beyond the standard Class B CDL.
Age and basic requirements to start
You must be at least 18 years old to get a Class B CDL in most states. However, if you plan to drive across state lines, federal rules require you to be 21. Some states set the minimum at 21 for all bus driving, so check your state's DMV website.
You must also have a valid regular driver's license (a Class D or Class C license, depending on your state) before you can get a CDL. If your regular license is suspended or revoked, you cannot get a CDL until it is restored. You need a Social Security number and proof of legal residency or citizenship to explore.
Your driving record matters. If you have serious violations like DUIs, reckless driving, or multiple traffic tickets, some states may deny you a CDL or require you to wait a certain amount of time before explore.
The medical exam and DOT certificate
Before you take any CDL test, you must pass a Department of Transportation (DOT) medical examination. This is not optional — without a medical certificate, your state will not let you test for a CDL.
The exam checks your vision, hearing, blood pressure, and overall health. A DOT-certified medical examiner (usually a doctor or nurse practitioner) performs the exam. You can find examiners through your state's DMV website or by searching "DOT medical examiner near me." The exam costs between $75 and $150 in most states.
If you pass, the examiner gives you a medical certificate valid for two years. You must carry this certificate with you when you drive a bus. If you fail, you may be able to retake it after treating the medical issue, or you may need to appeal to your state's medical review officer.
Written test on bus operation and safety rules
Your state's DMV will give you a written test covering bus-specific knowledge. This test is different from the written test for a regular driver's license. You will answer questions about air brake systems, passenger safety, loading procedures, and how to handle emergencies.
Most states let you study a CDL manual or handbook before you test. You can read it free from your state's DMV website. The test usually has 50 to 80 questions, and you must score at least 80 percent to pass. You can usually retake it the same day if you fail, though some states require you to wait a few days.
Some states offer the written test at the DMV office, while others offer it online. Check your state's DMV website to see where and when you can test.
Pre-trip inspection test and road test in a bus
After you pass the written test, you take a pre-trip inspection test. You walk around an actual bus and point out safety features and potential problems — things like tire condition, brake fluid, mirrors, lights, and emergency exits. An examiner watches and scores you on how thoroughly you check the bus.
The road test is the final step. You drive an actual bus on public roads while an examiner sits with you and scores your driving. You will be tested on starting and stopping smoothly, turning, backing up, parking, and handling traffic. The examiner also watches how you interact with passengers and follow safety rules.
You must pass all three parts — written, pre-trip, and road test — to get your CDL. If you fail any part, you can retake it, though some states require you to wait a few days between attempts.
CDL training schools and how they help
Many states do not require formal training, but most bus drivers go through a CDL training school before they test. These schools teach you how to operate a bus, pass the pre-trip inspection, and pass the road test. Training usually takes two to six weeks, depending on the program.
A training school gives you hands-on practice in a real bus with an instructor before you face the state examiner. This practice makes a big difference — people who train are more likely to pass the road test on their first try. Training schools also teach you the rules and safety procedures specific to bus driving.
Training schools cost between $3,000 and $7,000, depending on the length and location. Some employers, unions, or community colleges offer training at lower cost or even free if you commit to working for them after you get your license. Ask your local transit agency or school district whether they offer training programs.
School bus drivers and additional requirements
If you want to drive a school bus, you need a Class B CDL plus a school bus endorsement. The endorsement requires an additional written test on school bus rules, passenger management, and emergency procedures. You also take a road test in a school bus.
School bus drivers must pass a background check and fingerprinting in all states. Many states also require you to pass a child abuse and neglect check. Some states require a physical exam beyond the DOT medical exam. Check your state's Department of Education website for the exact requirements in your state.
School bus drivers may also need to complete first aid and CPR training, and some states require ongoing training each year. Pay and benefits for school bus drivers vary widely by district, but many offer health insurance and pension plans.
Renewing and maintaining your bus driver license
A Class B CDL is usually valid for four to eight years, depending on your state. You must renew it before it expires by passing another written test and medical exam. Some states let you renew by mail or online if you have no violations, while others require you to come to the DMV in person.
You must keep your medical certificate current at all times. If your medical certificate expires, your CDL becomes invalid until you get a new one. You cannot drive a bus with an expired medical certificate, even if your CDL itself is still valid.
If you get a traffic ticket or violation while driving a bus, it goes on your CDL record. Serious violations can result in suspension or revocation of your CDL. Keep your driving record clean by following traffic laws and safety rules.
Frequently Asked Questions
Can I get a bus driver license if I have a DUI on my record?
Most states will not issue a CDL if you have a DUI within the past 10 years. Some states have a lifetime ban. Check your state's DMV website or call to find out the specific rule in your state. If you are denied, you may be able to appeal after a certain amount of time has passed.
Do I need to take a CDL training school or can I just study on my own?
Most states do not require formal training, so you can study the manual and take the tests on your own. However, the road test is much harder without hands-on practice in a bus. Most people who pass on the first try have gone through a training school or had significant practice with an experienced driver.
How long does it take to get a bus driver license from start to finish?
If you already have a regular driver's license and a medical certificate, it can take as little as a few weeks if you study quickly and pass all tests on the first try. With formal training, expect two to six weeks for the school, plus a few weeks to schedule and take your DMV tests. The whole process often takes two to three months.
What happens if I fail the road test?
You can retake the road test, though most states require you to wait a few days between attempts. You do not have to retake the written test or pre-trip inspection if you only failed the road test. Many people pass on their second or third try, especially if they get more practice between attempts.
Can I drive a bus with a regular driver's license?
No. Driving a bus without a Class B CDL is illegal and can result in fines, criminal charges, and civil liability if someone is injured. You must have a valid CDL and medical certificate to operate any bus carrying passengers for money.
