A Class B license in Texas lets you drive a single vehicle: a bus carrying passengers for compensation.
This is not a general-purpose license. You cannot use it to drive a personal car, a truck, or any other vehicle. A Class B is issued only to people who operate buses — school buses, transit buses, tour buses, or shuttle buses — as part of their job. If you drive a bus and get paid for it, Texas requires you to hold a Class B license.
The restriction exists because bus operation carries specific safety risks: you are responsible for multiple passengers, you operate a larger vehicle with different handling characteristics, and you need training that a standard driver does not. Texas separates this into its own license class to may support only trained operators drive buses.
Key Takeaways
- A Class B license permits you to drive only a bus designed to carry 16 or more passengers, and only if you are paid to operate it.
- You must pass a written knowledge test, a skills test behind the wheel, and a medical examination before you receive a Class B license.
- The skills test includes a pre-trip vehicle inspection, basic control movements, and an on-road driving segment — all in an actual bus.
- You can add endorsements to a Class B license to operate buses with air brakes or to transport hazardous materials, but each requires additional testing.
- A Class B license is valid for five years in Texas and requires renewal at your local Department of Public Safety office.
Who needs a Class B license
You need a Class B license if you operate a bus as your job. The bus must be designed to carry 16 or more passengers. This includes school bus drivers, city transit operators, intercity bus drivers, charter bus operators, and shuttle drivers for hotels, airports, or other businesses.
If you drive a van that carries fewer than 16 passengers, you do not need a Class B license — a standard Class C license is sufficient. The 16-passenger threshold is the dividing line. If the vehicle is designed to seat 16 or more, and you are paid to drive it, you must hold a Class B.
The written knowledge test
Before you take the skills test, you must pass a written exam at your local Department of Public Safety office. The test covers bus operation, passenger safety, vehicle inspection, and Texas traffic laws. You answer 50 multiple-choice questions and must score at least 80 percent to pass.
The test draws from the Texas Commercial Driver License Manual, which is available free online at the DPS website. Most people study this manual for several weeks before taking the test. You can take the test as many times as needed, but you must pass before scheduling a skills test.
The skills test and what to expect
The skills test happens in three parts, all conducted in an actual bus. You will need to bring a bus to the testing location — your employer usually provides one, or you can rent a bus from a commercial driving school. The test takes about an hour and a half.
The first part is a pre-trip inspection. The examiner asks you to walk around the bus and point out safety features: lights, mirrors, brakes, tires, and emergency equipment. You must demonstrate that you know where these items are and what condition they should be in. This is not a written test — you physically show the examiner.
The second part is basic control movements. You drive the bus in a closed course and perform specific maneuvers: backing in a straight line, backing into an offset alley, and backing into a 90-degree angle. These movements test your ability to handle the bus's size and weight in tight spaces.
The third part is on-road driving. You drive the bus on public roads for about 20 to 30 minutes while the examiner observes. You will encounter traffic, intersections, turns, and possibly highway driving. The examiner is looking for smooth acceleration and braking, proper lane positioning, awareness of other vehicles, and safe decision-making.
Medical certification and other requirements
You must pass a medical examination performed by a certified medical examiner. The examiner checks your vision, hearing, blood pressure, and overall health. You cannot have certain medical conditions — uncontrolled diabetes, heart disease, or severe sleep apnea — that would make bus operation unsafe. Your doctor can refer you to a medical examiner if you are unsure whether you will pass.
You also need a valid Social Security number and proof of Texas residency. Bring your current driver license, birth certificate or passport, and proof of address (a utility bill or lease works). If you have a commercial driver license from another state, you may be able to transfer it rather than take the full test, but you still need the medical exam.
Endorsements for air brakes and hazardous materials
A standard Class B license does not permit you to operate a bus with air brakes or to transport hazardous materials. If your job requires either, you must add an endorsement to your license.
An air brake endorsement requires a written test covering air brake systems, maintenance, and operation. A hazmat endorsement requires a written test and a background check. Both endorsements add to your Class B license and are noted on the license itself. Your employer will tell you which endorsements you need before you start the job.
License validity and renewal
A Class B license is valid for five years from the date it is issued. You renew it at your local Department of Public Safety office. Renewal requires passing the medical examination again — the written and skills tests are not required unless your license was suspended or revoked.
If your license expires, you cannot legally operate a bus. If you let it lapse for more than two years, you will need to retake the written and skills tests to restore it. Most employers remind drivers when renewal is approaching, but it is your responsibility to schedule the appointment and complete the process on time.
Frequently Asked Questions
Can I use a Class B license to drive my personal vehicle?
No. A Class B license is restricted to buses only. If you need to drive a personal car, truck, or van, you must hold a separate Class C license. Some people hold both licenses, but they are issued separately and each has its own restrictions.
What happens if I drive a bus without a Class B license?
Operating a bus without the required license is a criminal offense in Texas. You can be fined, arrested, and your vehicle can be impounded. Your employer can also face penalties. If you are hired to drive a bus, you must obtain the license before you start work.
How long does it take to get a Class B license from start to finish?
Most people take four to eight weeks. This includes time to study for the written test (two to four weeks), scheduling and passing the written test (one week), scheduling and passing the skills test (one to two weeks), and waiting for the license to be issued (a few days). The timeline depends on how quickly you study and how soon testing appointments are available.
Do I need a Class B license if I drive a school bus but am not paid?
If you are a volunteer and receive no compensation, you do not need a Class B license. However, most school districts require all drivers — paid or volunteer — to hold a Class B for liability and safety reasons. Check with your school district before assuming you are exempt.
Can I transfer my Class B license from another state?
Yes, if you hold a valid Class B or equivalent commercial license from another state, you can transfer it to Texas. You will still need to pass the medical examination and provide proof of residency. Contact your local DPS office to learn what documents you need to bring.
