What a Class B license is and who needs one
A Class B license lets you drive vehicles heavier than a standard passenger car but smaller than a full commercial truck. The exact weight threshold varies by state — most define it as vehicles between 10,001 and 26,000 pounds gross vehicle weight rating (GVWR). Common vehicles you can drive with a Class B include delivery trucks, small box trucks, passenger vans with more than 15 seats, and some RVs.
You need a Class B if your job or personal use requires driving one of these vehicles regularly. If you drive a 16-passenger van for a nonprofit, operate a small delivery truck, or own an RV above the weight limit for a regular license, your state's Department of Motor Vehicles (DMV) will require you to hold a Class B. Driving one of these vehicles without the proper license class is illegal and can result in fines, license suspension, or both.
The process to obtain a Class B takes longer than renewing a standard license because it includes a written knowledge test, a skills test, and a medical examination in most states. Plan for several weeks from start to finish, depending on how quickly you can schedule your tests and how many attempts you need.
Key Takeaways
- You must pass a written knowledge test specific to Class B vehicles, a practical driving skills test, and a Department of Transportation medical exam before your state will issue the license.
- Requirements and fees vary significantly by state — contact your state DMV directly to learn the exact documents, tests, and costs for your location.
- Most states require you to hold a valid regular driver's license before you can test for a Class B, and some require a waiting period between your written test and your driving test.
- You will need to provide proof of identity, residency, and Social Security number, plus documentation of your medical exam results to complete the process.
Check your state's specific requirements before you start
Every state sets its own rules for Class B licensing, so the first step is to contact your state's DMV or visit its website to confirm what you need. Some states call it a Class B, others use different names — California calls it a Class 2, for example. The weight thresholds, required tests, medical standards, and fees all differ.
Write down or print the requirements for your state, including the process fee, test fees, medical exam requirements, and any documents you need to bring. Many state DMV websites have a checklist you can read. If the website is unclear, call your local DMV office directly — they can tell you exactly what to prepare and whether you need to schedule appointments in advance.
Some states require you to hold a regular driver's license for a minimum period (often 12 months) before you can test for a Class B. Others let you test for both at the same time. Knowing this early saves you from showing up unprepared.
Get a Department of Transportation medical exam
Most states require a DOT physical — a medical examination performed by a certified DOT medical examiner — before you can obtain a Class B license. This is not a full physical; it focuses on vision, hearing, blood pressure, and ability to operate a large vehicle safely. The exam typically costs between $75 and $150, though prices vary by provider and location.
Find a DOT medical examiner through your state's DMV website or by searching "DOT medical examiner near me." Call ahead to confirm they are currently accepting new patients and what documents to bring (usually your ID and insurance card). Schedule the exam before you take your written test, because you will need the results when you explore for your license.
The examiner will give you a form or certificate showing you passed. Keep this document — you will submit it with your process. If you fail the exam, you can retest after addressing the issue (such as getting glasses if your vision is below standard). Some states allow you to proceed with the written test while waiting for medical clearance, but most require the medical exam to be complete before you schedule your driving test.
Study for and pass the Class B written knowledge test
The written test covers vehicle operation, safety rules specific to larger vehicles, and road signs. Most states offer a study guide or manual on their DMV website — read it and read it thoroughly. The test is usually 50 questions, and you must score at least 80 percent to pass (the exact passing score varies by state).
Topics on the test typically include air brake systems, load securement, vehicle inspection procedures, and how to handle larger vehicles in traffic. If you have never driven a truck or large van, these concepts may be new to you. Spend extra time on the study guide sections about braking, turning radius, and backing up, as these are common weak points.
Schedule your written test through your state's DMV. Some states let you test at any DMV office; others require you to go to a specific location. Bring your ID, proof of residency, and your Social Security number. Most states allow you to retake the test if you fail, but you will pay the test fee again and may have to wait a few days before retesting.
Schedule and pass your Class B driving skills test
After you pass the written test, you will schedule a practical driving test with a DMV examiner. This test takes 30 to 45 minutes and happens in an actual Class B vehicle — usually one provided by the DMV or a testing facility. The examiner watches you perform basic maneuvers: starting and stopping, turning, backing up, parking, and driving on public roads.
Before your test date, practice driving the specific type of vehicle you will be tested in if possible. If you work for a company that uses these vehicles, ask if you can practice during off-hours. If not, some driving schools offer Class B test preparation. The key skills examiners watch for are smooth braking (especially important with air brakes), awareness of the vehicle's size, and safe lane changes.
Bring your ID, proof of residency, your passing written test score, and your medical exam results to your driving test. Arrive 15 minutes early. If you fail, you can retake the test, but there is usually a waiting period (often 7 to 14 days) and another test fee. Most people pass on their second attempt if they practice between tests.
Submit your process and pay the license fee
Once you have passed both tests and completed your medical exam, return to your DMV office to submit your formal process. Bring all required documents: your ID, proof of residency (usually a utility bill or lease), your Social Security number, your passing test scores, and your medical exam results. Some states also require proof of your current address if it differs from your ID.
Pay the license fee, which varies by state but typically ranges from $50 to $200 for a Class B. Some states charge extra if you are upgrading from a regular license rather than obtaining a new one. Ask whether your license will be issued when ready or mailed to you — most states mail it within one to two weeks.
Keep your receipt and any temporary license document the DMV gives you. If you need to drive a Class B vehicle before your permanent license arrives, the temporary document proves you have passed all requirements.
Renew your Class B license before it expires
Class B licenses expire on a schedule set by your state — typically every four to eight years. Your license will show the expiration date. Most states let you renew by mail, online, or in person, though some require an in-person visit and a new medical exam.
Start the renewal process at least 30 days before your license expires. Check your state's DMV website for the renewal procedure and whether you need a new medical exam. Some states require a fresh DOT physical every few years; others only require it when you first obtain the license. Renewing early prevents you from driving illegally if your license lapses.
Frequently Asked Questions
Do I need a regular driver's license before I can get a Class B?
Most states require you to hold a valid regular driver's license (Class D or equivalent) before you can test for a Class B. Some states also require you to have held it for a minimum period, often 12 months. Check your state's DMV website to confirm whether you can test for both at the same time or must wait.
What happens if I fail the driving test?
You can retake the test after a waiting period, usually 7 to 14 days. You will pay the test fee again. Most people pass on their second attempt if they practice between tests. Ask the examiner for specific feedback on what you did wrong so you can focus your practice.
Can I use my own vehicle for the driving test?
No. The DMV provides the vehicle for your driving test, or you test in a vehicle at an approved testing facility. This ensures all test-takers are evaluated on the same equipment under the same conditions. You cannot bring your own truck or van.
How long does it take to get a Class B license from start to finish?
The timeline varies by state and how quickly you can schedule tests, but plan for four to eight weeks. This includes time to study, schedule your medical exam, take the written test, wait for your driving test appointment, and receive your license in the mail. Expedited processing may be available in some states for an additional fee.
Do I need to take the written test again if I already have a regular driver's license?
Yes. The Class B written test covers vehicle-specific topics that are not on the regular driver's license test. You must pass the Class B test even if you have held a regular license for many years.
