What a Class B License Lets You Drive

A Class B driver's license permits you to operate single vehicles with a gross vehicle weight rating (GVWR) between 26,001 and 33,000 pounds — typically delivery trucks, box trucks, and some transit buses. You cannot tow a trailer with a Class B license unless the trailer weighs 10,000 pounds or less. The exact rules depend on your state; some states call this a "Medium Duty" or "Class 2" license, and the weight thresholds vary slightly.

Class B sits between a standard Class C (passenger vehicle) license and a Class A (tractor-trailer) license. If your job involves driving a delivery truck for a moving company, a box truck for a rental agency, or a small bus for a shuttle service, you will need at least a Class B. Many employers require this license before they will hire you for those roles.

You do not need a Class B to drive a pickup truck or SUV, even a large one, unless it exceeds your state's GVWR threshold. Check your vehicle's registration or door placard to confirm the GVWR before assuming you need an upgrade.

Key Takeaways

  • A Class B license covers vehicles weighing 26,001 to 33,000 pounds GVWR, depending on your state's specific rules.
  • You must pass a written knowledge test, a skills test (backing and parking maneuvers), and a medical examination before you receive the license.
  • Most states require you to hold a valid Class C license for a set period (often 6 to 12 months) before you can test for Class B.
  • The written test covers vehicle operation, weight distribution, braking, and safety rules specific to larger vehicles.
  • Testing fees and processing timelines vary by state; contact your DMV directly for the exact cost and wait time in your location.

Age and Licensing History Requirements

You must be at least 18 years old to test for a Class B license in most states. Some states set the minimum at 21, particularly if you plan to drive commercially. Check your state's DMV website or call their main line to confirm the age rule where you live.

Most states require you to hold a valid Class C (standard passenger) license for a minimum period — typically 6 to 12 months — before you can test for Class B. This waiting period exists to may support you have demonstrated safe driving habits. If you have a suspended or revoked license, you will need to restore it and wait out the required period before you can move forward.

Some states waive or shorten the waiting period if you are testing for Class B as part of a commercial driver's license (CDL) program through an accredited school. If you are enrolled in a truck driving school or similar program, ask the school whether they have a relationship with your state's DMV that could accelerate the process.

Documents You Need to Bring

Bring your current Class C driver's license, a state-issued ID, or a passport to prove your identity. You will also need proof of your Social Security number — typically a Social Security card, W-2, or 1099 form. Some states accept a birth certificate as an alternative.

Bring proof of your state residency: a utility bill, lease agreement, mortgage statement, or bank statement dated within the last 60 days. A few states accept a recent tax return or vehicle registration instead. The document must show your current address and your name.

If you have changed your name since your last license was issued, bring a marriage certificate, divorce decree, or court order documenting the change. You will also need to bring any medical certification or vision test results if your state requires them before testing. Check your state's DMV website for the exact list, as requirements vary.

The Written Knowledge Test

The written test covers vehicle operation and safety specific to larger vehicles. You will answer questions about air brake systems, weight distribution, load securement, stopping distance, and how to handle a vehicle with higher center of gravity. The test typically includes 30 to 50 multiple-choice questions, and you must score 80 percent or higher to pass.

Study materials are free on your state's DMV website. read the Class B or Medium Duty study guide and review it thoroughly before your test date. Many states also offer practice tests online. The test is administered on a computer at your local DMV office, and you receive your score when ready.

If you fail the written test, you can usually retake it the same day or within a few days, depending on your state's policy. There is typically no additional fee for a retest, but confirm this with your DMV before you test.

The Skills Test and Road Examination

After you pass the written test, you must schedule a skills test with a DMV examiner. This test takes place in an actual Class B vehicle — usually provided by a testing facility or your employer — and lasts 30 to 45 minutes. The examiner watches you perform a series of maneuvers: backing in a straight line, backing into a 90-degree angle, parking between two vehicles, and navigating turns with a longer wheelbase.

You will also drive on public roads under the examiner's observation. The examiner evaluates your ability to control the vehicle, check your mirrors, maintain safe speed, and respond to traffic. Common reasons for failure include hitting cones during backing maneuvers, failing to signal, or unsafe lane changes.

Bring the same documents you brought for the written test, plus proof of vehicle insurance if you are using your own vehicle. If you are using a testing facility's vehicle, they will handle insurance. Schedule your skills test well in advance — wait times can be 2 to 8 weeks depending on your state and season.

Medical Examination and Vision Requirements

Most states require a medical examination and vision test before you receive a Class B license. The vision test checks your acuity (usually 20/40 or better in each eye) and your peripheral vision. If you wear glasses or contacts, you must wear them during the test, and your license will be restricted to "corrective lenses required."

The medical examination is typically a basic screening performed by a DMV-certified examiner or your own physician. The examiner checks your hearing, blood pressure, and general health to may support you are safe to operate a larger vehicle. If you have a medical condition — such as diabetes, epilepsy, or heart disease — you may need additional documentation from your doctor before the DMV will issue the license.

Some states require the medical exam to be completed within a certain timeframe before you test (often 30 to 60 days). Schedule your exam early so you have the results in hand when you arrive for your written test. The exam fee varies by state and provider, typically between $25 and $75.

Fees, Processing Time, and Renewal

Class B license fees vary widely by state. Testing fees (written and skills combined) typically range from $50 to $150. The license itself costs between $30 and $100 for a standard term, which is usually 4 to 8 years depending on your state. Some states charge a higher fee for a commercial Class B than for a non-commercial one.

Processing time from the date you pass your skills test to the date you receive your license in the mail is typically 1 to 3 weeks. If you need the license sooner, some DMV offices offer expedited processing for an additional fee. A few states allow you to print a temporary license when ready after you pass your test.

Class B licenses renew on the same schedule as your Class C license. Most states require you to renew in person and retake the vision test, though a few allow mail-in renewal if you have no violations. You do not have to retake the written or skills test unless your license was suspended or revoked.

Common Mistakes to Avoid

Do not assume your current Class C license automatically upgrades to Class B. You must test separately and pass both the written and skills components. Some people schedule only the written test and are surprised to learn they must return for a separate skills appointment.

Do not bring an expired ID or proof of residency. The DMV will turn you away, and you will lose your testing appointment. Bring documents dated within the last 60 days for residency and may support your ID is current.

Do not skip the study guide. The written test includes questions about air brakes, weight limits, and vehicle-specific safety that are not covered on a Class C test. People who study only from memory of their Class C test often fail.

Do not schedule your skills test before you have practiced backing and parking maneuvers in an actual Class B vehicle. Many testing facilities offer practice sessions for a fee. A few hours of practice significantly increases your pass rate.

Frequently Asked Questions

Do I need a Class B license to drive a pickup truck?

Only if the truck's GVWR exceeds your state's Class C threshold, which is typically 26,000 pounds. Check your vehicle's registration or the door placard for the GVWR. Most pickup trucks fall below this, so you do not need an upgrade.

Can I test for Class B if my Class C license is suspended?

No. You must have a valid, unrestricted Class C license and typically must have held it for 6 to 12 months before you can test for Class B. Restore your license first, wait out the required period, then test.

What happens if I fail the skills test?

You can retake it, usually within a few days to a few weeks depending on your state's availability. There is typically no additional fee for a retest. Most people pass on their second attempt after additional practice.

Do I need to take a Class B test if I already have a CDL?

No. A CDL (commercial driver's license) covers Class B vehicles and heavier. If you hold a valid CDL, you do not need a separate Class B license.

How long is a Class B license valid?

Most states issue Class B licenses for 4 to 8 years, the same as a Class C license. Check your state's DMV website for the exact term. Your renewal date appears on the front of your license.
