What a Class B license is and who needs one
A Class B license in Texas lets you drive a single vehicle with air brakes, or any vehicle without air brakes that weighs more than 26,001 pounds. The most common Class B drivers are people operating straight trucks, dump trucks, or box trucks for work. You need a Class B if your job involves hauling cargo or materials in a vehicle that crosses that weight threshold, even if you only drive it occasionally.
The difference between Class B and a regular passenger license (Class C) comes down to vehicle size and the skills required to operate it safely. A Class B vehicle handles differently — it has a longer stopping distance, wider turning radius, and different blind spots. Texas requires you to prove you understand these differences through testing and training before you can legally drive one for work.
If you drive a vehicle that weighs 26,001 pounds or more, or one with air brakes, you cannot use a Class C license, even if you own the vehicle personally. Driving without the correct license class can result in fines and a citation on your driving record.
Key Takeaways
- You need a Class B license to drive a single vehicle over 26,001 pounds or any vehicle with air brakes in Texas.
- The Texas Department of Public Safety (DPS) issues Class B licenses after you pass a written test, a skills test, and a medical exam.
- You must hold a valid Class C license first, then add the Class B endorsement to it.
- The skills test happens in a vehicle that meets the Class B weight requirement, so you will need access to one before your test date.
- The entire process typically takes a few weeks from start to finish, depending on how quickly you schedule your tests.
Step 1: Get a medical certificate from a certified examiner
Before you can test for a Class B license, you must have a medical certificate on file with the Texas Department of Public Safety. This is not a full physical — it is a brief health screening that confirms you can safely operate a large vehicle. The examiner checks your vision, hearing, and general ability to control a vehicle, and looks for any medical conditions that would make driving unsafe.
You need to visit a certified medical examiner listed on the Federal Motor Carrier Safety Administration (FMCSA) website. Search for examiners in your area at fmcsa.dot.gov under the National Registry of Certified Medical Examiners. The exam costs between $75 and $150, depending on the examiner. Bring your current driver's license and be prepared to answer questions about your medical history.
The examiner will give you a copy of the medical certificate (Form MCSA-5875) on the spot. You will need this form when you go to the DPS office to test. The certificate is valid for two years.
Step 2: Study for the written test and gather your documents
The Class B written test covers vehicle operation, safety rules, and air brake systems. You can study using the Texas Commercial Driver License Manual, which is free and available on the DPS website at dps.texas.gov. The manual explains everything the test covers, including how to inspect a Class B vehicle, how air brakes work, and how to handle emergency situations.
Before you go to the DPS office, gather these documents: your current valid Texas driver's license, your medical certificate (Form MCSA-5875), proof of Texas residency (a utility bill or lease dated within the last 60 days), and your Social Security number. If you have changed your name, bring a certified copy of the document that shows the change (marriage certificate, court order, or divorce decree).
The written test has 50 questions, and you must answer at least 40 correctly to pass. You can take it at any DPS office that issues commercial licenses. There is no fee for the written test itself.
Step 3: Pass the written test at a DPS office
Go to your local DPS office during business hours with your documents and medical certificate. Tell the clerk you want to test for a Class B license. They will verify your documents, take a new photo, and direct you to a testing station. The written test is given on a computer and takes about 30 to 45 minutes.
You will receive your score when ready after you finish. If you pass, the clerk will schedule your skills test and give you a temporary permit that allows you to drive a Class B vehicle with a licensed trainer or supervisor while you prepare. If you do not pass, you can retake the written test the same day or come back another day at no additional cost.
After you pass the written test, you have 30 days to schedule and pass your skills test. If you do not pass the skills test within 30 days, you will have to retake the written test.
Step 4: Arrange a Class B vehicle for your skills test
Your skills test must be done in an actual Class B vehicle — one that weighs more than 26,001 pounds or has air brakes. You cannot use a simulator or a lighter truck. This is where many people get stuck, because not everyone has access to a truck that size.
If you do not own a Class B vehicle, ask your employer if you can use one of theirs for the test. Some trucking schools and commercial driving programs also rent vehicles for testing purposes. Call ahead to confirm availability and cost. You will need the vehicle for about two hours on the day of your test.
The vehicle must be in safe working condition and properly registered. Bring proof of registration and insurance when you show up for your test. The examiner will inspect the vehicle before the test begins to make sure it meets safety standards.
Step 5: Take the skills test with a DPS examiner
The skills test has three parts: a pre-trip inspection, a basic control test, and an on-road driving test. The entire test takes about 45 minutes to an hour.
In the pre-trip inspection, the examiner asks you to walk around the vehicle and point out safety features and potential problems. You will need to show you know where the lights are, how to check the tires and brakes, and how to spot damage. This part tests whether you understand the vehicle well enough to catch problems before you drive.
In the basic control test, you drive the vehicle in a closed course — usually a parking lot or a small track — and perform maneuvers like backing up, turning, and stopping. The examiner watches how you handle the size and weight of the vehicle and whether you stay in control.
In the on-road test, you drive on public streets with the examiner in the passenger seat. You will encounter traffic, turns, hills, and other real-world conditions. The examiner is watching for safe driving habits, proper use of mirrors, smooth braking, and awareness of the vehicle's size and limitations.
What happens after you pass
Once you pass all three parts of the skills test, the examiner will tell you on the spot. You will go back to the DPS office, and the clerk will issue your Class B license. Your new license will show the Class B designation and any endorsements you have earned (such as an air brake restriction or hazmat endorsement, if you tested for those).
Your Class B license is valid for five years. You can renew it by mail or online before it expires, as long as you do not have any medical changes that would affect your ability to drive. If your medical certificate expires before your license does, you will need to renew the medical certificate to keep driving a Class B vehicle.
Keep a copy of your medical certificate with you whenever you drive a Class B vehicle. Some employers and law enforcement may ask to see it.
Frequently Asked Questions
Can I test for a Class B license if I do not have a Class C license yet?
No. You must have a valid Class C (regular passenger) driver's license before you can test for a Class B. If you do not have one, you will need to get your Class C license first by passing the written and skills tests for a regular vehicle.
What if I fail the skills test?
You can retake the skills test as many times as you need. There is a fee each time you retake it — currently around $100 per attempt, though this varies by DPS office. You have 30 days from the date you passed the written test to pass the skills test before you have to retake the written test as well.
Do I need to take a commercial driving school course?
No, it is not required by Texas law. However, many people find that a few hours of professional instruction help them pass the skills test on the first try. Some employers require or pay for this training. If you choose to take a course, look for one approved by the DPS.
What is the difference between a Class B and a Class A license?
A Class A license allows you to drive any combination of vehicles (like a tractor-trailer), while a Class B is limited to a single vehicle over 26,001 pounds. Class A requires more training and a more difficult skills test. If you think you might need to drive a tractor-trailer in the future, you may want to go straight for Class A instead.
How much does it cost to get a Class B license?
The medical exam costs $75 to $150. The DPS written test is free. The skills test costs around $100 per attempt. If you use a commercial driving school, that can range from $300 to $1,000 depending on the program. The total out-of-pocket cost is typically $500 to $1,500, not counting the cost of renting a vehicle for the test if you do not have access to one.
