A Class B license is for driving single vehicles that are heavier or larger than a regular passenger car, but not heavy commercial trucks
A Class B driver's license sits between a standard Class D (or Class C in some states) license for regular cars and a Class A or commercial license for the largest trucks. The exact weight and size limits depend on your state, but generally a Class B lets you drive vehicles over a certain weight threshold — often 26,001 pounds or more — without needing a commercial license.
The key difference from a regular license is that you need a Class B to legally operate these larger vehicles on public roads. Driving one without the proper license class can result in fines, points on your record, or both. The requirements to get a Class B are stricter than for a regular license: you typically need to pass a written test specific to larger vehicles, a skills test, and sometimes a medical exam.
Key Takeaways
- A Class B license covers single vehicles above a certain weight — usually 26,001 pounds — but excludes vehicles with air brakes or multiple trailers.
- You must pass a written knowledge test and a behind-the-wheel driving test specific to Class B vehicles to get this license.
- Some states require a medical examination and proof of vision standards before issuing a Class B.
- The cost and processing time vary by state, but expect to pay a higher fee than a regular license and wait several weeks for approval.
What vehicles you can and cannot drive with a Class B
A Class B license typically covers single vehicles — meaning one truck or bus, not a truck with a trailer attached. The vehicle usually must weigh more than 26,001 pounds, though some states use different thresholds. Common vehicles include large straight trucks, dump trucks, box trucks, and some buses.
You cannot drive a vehicle with air brakes, a trailer, or multiple units with a Class B alone. If the vehicle has air brakes, you need an air brake endorsement added to your Class B. If you want to tow a trailer, you need a Class A commercial license instead. The specific rules vary by state, so check your state's Department of Motor Vehicles (DMV) or equivalent agency for the exact weight limits and vehicle types.
How to get a Class B license in your state
The process starts with visiting your state's DMV or licensing office in person. You will need to bring proof of identity, proof of residency, and your current driver's license. Some states require a medical examination form completed by a doctor, confirming you meet vision and hearing standards. Check your state's website before you go, because requirements vary.
Next, you take a written test covering Class B vehicle operation, safety, and road rules specific to larger vehicles. The test is usually on a computer or paper, and you need to pass with a score that varies by state — often 80 percent or higher. After passing the written test, you schedule a behind-the-wheel driving test. You bring a Class B vehicle (or rent one from a testing facility) and demonstrate your ability to operate it safely, including backing up, turning, and parking.
Once you pass both tests, the DMV issues your Class B license. Processing time ranges from a few days to several weeks depending on your state and how busy the office is. Some states offer expedited processing for an additional fee.
Medical requirements and vision standards
Many states require a medical examination before issuing a Class B license, especially if you plan to use it for commercial purposes. A doctor or certified medical examiner must complete a form — often called a Medical Examiner's Certificate or DOT physical form — confirming you meet federal or state health standards.
Vision requirements typically include corrected or uncorrected vision of at least 20/40 in each eye, and a field of vision of at least 70 degrees in each direction. Hearing standards vary by state; some require a hearing test, while others do not. If you wear glasses or contacts, you must wear them during your driving test and note the restriction on your license. Your doctor's form must be submitted with your process.
Costs and timeline for getting a Class B license
The cost of a Class B license varies significantly by state. Some states charge $50 to $100 for the license itself, plus separate fees for the written test ($10 to $30) and the driving test ($50 to $150). Medical examination costs are usually your responsibility and can range from $50 to $200 depending on your doctor. Add in the cost of renting a vehicle for the driving test if you do not own one — typically $100 to $300 for a few hours.
The timeline depends on how quickly you pass the tests and how busy your DMV is. If you pass both tests on your first attempt, you may receive your license within one to three weeks. If you need to retake a test, add another week or two. Some states offer rush processing that can reduce the wait to a few days, but this usually costs extra.
Endorsements and restrictions you might need
An endorsement is an additional permission added to your Class B license that expands what you can drive. The most common is an air brake endorsement, which you need if the vehicle has air brakes. To get it, you pass an additional written test covering air brake systems and maintenance. This usually takes one to two weeks and costs $10 to $50.
A restriction is the opposite — it limits what you can do with your license. Common restrictions include "corrective lenses required" (you must wear glasses or contacts), "daylight driving only," or "no interstate driving." Restrictions appear on your license and are legally binding. If you violate a restriction, you can be cited just as if you were driving without the proper license class.
Renewing and maintaining your Class B license
A Class B license typically expires every four to eight years, depending on your state. Renewal usually requires passing the written test again, though some states waive the driving test for renewals if you have a clean record. You may also need to renew your medical examination form if your state requires one.
Renewal can often be done by mail or online in some states, but check your DMV's website to confirm. If you let your license expire, you may need to retake both the written and driving tests to restore it, so mark your expiration date on your calendar and renew before it lapses.
Frequently Asked Questions
Do I need a Class B license to drive a moving truck?
It depends on the truck's weight. If it weighs 26,001 pounds or more, most states require a Class B. Rental companies can tell you the vehicle's weight; if it is under the threshold, your regular license works. Check your state's specific weight limit before renting.
Can I get a Class B license if I have had traffic violations?
Most states do not automatically disqualify you for traffic violations, but serious violations like DUI or reckless driving may prevent you from getting a commercial license. Contact your state DMV to ask about your specific record before explore.
What happens if I drive a Class B vehicle without the proper license?
You can be cited for operating a vehicle without the proper license class. Penalties vary by state but typically include fines ($100 to $500 or more), points on your record, and possible license suspension. The fine is separate from any other traffic violations.
Is a Class B license the same as a commercial driver's license?
No. A commercial driver's license (CDL) is a Class A or Class B used for commercial purposes — meaning you are paid to drive. A Class B can be non-commercial if you drive the vehicle for personal use. Some states distinguish between the two on the license itself.
Can I take the Class B driving test in my own vehicle?
Most states allow you to use your own vehicle if it meets the Class B weight and size requirements and is properly insured and registered. Some testing facilities provide vehicles for a fee if you do not have access to one. Call your DMV ahead of time to confirm what is allowed in your state.
