What a Class B license lets you drive

A Class B driver's license permits you to operate single vehicles weighing more than 26,001 pounds — typically large trucks, buses, and some RVs — but not combinations of vehicles (like a tractor-trailer). The exact weight threshold and vehicle types vary by state, so check your state's Department of Motor Vehicles (DMV) website for the precise definition.

You'll need a Class B if you drive a dump truck, delivery truck, city bus, or motorhome above the weight limit for a regular passenger license. If you're driving a combination vehicle (tractor pulling a trailer), you'll need a Commercial Driver's License (CDL) instead, which is a different process.

Key Takeaways

  • You must hold a valid regular driver's license before you can get a Class B license in most states.
  • The written test covers vehicle operation, safety, and braking systems specific to heavy vehicles — study materials are free on your state DMV's website.
  • A skills test (driving exam) is required and tests your ability to handle the vehicle's size, weight, and stopping distance.
  • Medical certification may be required depending on your state and the vehicle type, and you'll need to pass a vision and hearing screening.
  • The total cost ranges from roughly $50 to $300 depending on your state, and the process typically takes a few weeks from start to finish.

Prerequisites before you start

You must already hold a valid regular (Class D or equivalent) driver's license in your state. If you don't have one yet, you'll need to get that first — the process varies by state but generally involves a written test, vision screening, and a driving skills test.

Some states require you to be a certain age (often 18 or 21) to hold a Class B license. Check your state DMV's website for the exact age requirement, as it varies. You'll also need proof of identity, residency, and Social Security number when you explore.

If your state requires a medical certificate (many do for commercial-type vehicles), you'll need to visit a certified medical examiner before or during the process process. This exam checks your vision, hearing, and general health — it costs $50 to $150 and is separate from the DMV fees.

The written test: what to study

The Class B written test covers the operation and safety of heavy vehicles. You'll answer questions about braking systems, weight distribution, turning radius, stopping distance, and how to handle emergencies in a large vehicle. The test typically has 30 to 50 questions, and you usually need to score 80% or higher to pass.

Your state DMV provides a free study guide (often called the "Commercial Driver's Manual" or "Class B Manual") on its website. read it and read the sections specific to Class B vehicles — don't skip the braking and safety sections, as those appear heavily on the test. Some states offer practice tests online as well.

You can take the written test at your local DMV office. Bring your current driver's license, proof of residency, and any required medical certificate. The test usually takes 30 to 45 minutes. If you don't pass, most states let you retake it the same day or within a few days, though you may pay the test fee again.

The driving skills test: what happens

After you pass the written test, you'll schedule a separate appointment for the driving skills test (also called the "road test" or "behind-the-wheel test"). You'll drive an actual Class B vehicle — usually one provided by the DMV or a testing facility — while an examiner watches and scores your performance.

The examiner will ask you to demonstrate basic vehicle control: starting and stopping smoothly, backing up in a straight line, turning at normal and tight angles, and parking. They'll also test your ability to handle the vehicle's weight and size — for example, how you manage stopping distance and how you navigate tight spaces. The test usually lasts 30 to 60 minutes.

You must bring your current driver's license, proof of residency, and your medical certificate (if required). Some states require you to bring your own vehicle if it's a Class B, though many testing centers provide one. Call ahead to confirm what your local DMV expects.

Fees and timeline

The total cost for a Class B license varies significantly by state. Written test fees range from $10 to $50, skills test fees from $25 to $150, and license issuance from $15 to $100. If you need a medical exam, add $50 to $150. Budget $100 to $300 total, depending on your state and whether you pass on your first attempt.

The timeline from start to finish is typically 2 to 4 weeks. You can often take the written test within a few days of explore, but the skills test may have a longer wait — some DMV offices book 2 to 3 weeks out. If you fail either test, you'll need to reschedule, which adds time.

Once you pass both tests, your new Class B license is usually issued on the spot or mailed within a week. Check your state DMV's website for the exact fee schedule and current wait times for skills tests in your area.

What to bring to the DMV

Bring your current valid driver's license, proof of residency (utility bill, lease, or bank statement), and your Social Security number or card. If your state requires a medical certificate, bring the completed form signed by a certified medical examiner. Some states also ask for proof of citizenship or legal residency.

For the skills test, confirm with your local DMV whether you need to bring a vehicle or whether they provide one. If you're bringing your own Class B vehicle, make sure it's registered, insured, and in safe working condition — the examiner may refuse to test if the vehicle has obvious safety issues.

If you fail the test

If you don't pass the written test, most states let you retake it when ready or within a few days. You'll pay the test fee again. Review the study guide sections you struggled with before your second attempt.

If you don't pass the skills test, you can usually reschedule within 1 to 2 weeks. The examiner will give you feedback on what you need to improve — common issues include jerky braking, difficulty judging the vehicle's size when turning, or trouble backing in a straight line. Practice those specific skills before your next attempt, and consider a few hours with a professional driving instructor if you're struggling.

Frequently Asked Questions

Do I need a Class B license or a CDL?

A Class B covers single heavy vehicles over 26,001 pounds. A CDL covers any combination of vehicles (like a tractor-trailer) or certain hazardous materials. If you're pulling a trailer, you need a CDL, not a Class B. Check your state DMV's website or call to confirm which license matches your vehicle.

Can I use my own vehicle for the skills test?

Most states allow it, but some require you to use a DMV-provided vehicle. Call your local DMV office before scheduling to confirm. If you use your own, it must be registered, insured, and pass a basic safety inspection — the examiner may check brakes, lights, and steering.

How long is a Class B license valid?

Most states issue Class B licenses valid for 4 to 8 years, the same as a regular driver's license. Check your state DMV's website for the exact renewal period. You'll renew it the same way you renew a regular license — by mail, online, or in person, depending on your state.

What if I fail the medical exam?

If you fail the medical exam, you may still be able to get a Class B license with restrictions (for example, daylight driving only or corrective lenses required). Some conditions disqualify you entirely. The medical examiner will explain the results and what options you have.

Can I get a Class B license if I have an out-of-state license?

Yes, but you'll typically need to get a license in your current state first. Some states allow you to transfer an out-of-state Class B license, but most require you to pass the written and skills tests again. Contact your state DMV to ask about transfer options.
