A Class B license covers single vehicles over 26,000 pounds and certain combinations of smaller vehicles

A Class B license is a commercial driver's license (CDL) that permits you to operate a single vehicle with a gross vehicle weight rating (GVWR) of 26,001 pounds or more, as long as the vehicle is not pulling a trailer. It also covers some combinations of vehicles where the towed unit weighs less than 10,000 pounds. The specific rules depend on your state, but the federal baseline is consistent across all 50 states.

If you hold only a Class B, you cannot drive a Class A combination (a tractor pulling a trailer weighing 10,001 pounds or more). You also cannot operate a Class C vehicle, which covers smaller commercial vehicles or passenger vehicles carrying 16 or more people. A Class B sits in the middle of the CDL hierarchy and is the most common commercial license for drivers of delivery trucks, dump trucks, and box trucks.

Key Takeaways

  • A Class B CDL covers single vehicles weighing 26,001 pounds or more and some lighter trailer combinations, but not tractor-trailer rigs.
  • You must pass a written knowledge test, a skills test, and a medical examination to obtain a Class B license.
  • Most states require you to hold a regular driver's license for at least one year before you can test for a CDL.
  • A Class B license is valid for four or eight years depending on your state, and you must renew it in person at your state's motor vehicle office.
  • Violations and accidents on a commercial license carry harsher penalties than violations on a regular license, including possible disqualification.

What vehicles you can and cannot drive with a Class B

With a Class B license, you can operate any single vehicle with a GVWR over 26,000 pounds. This includes straight trucks like delivery trucks, garbage trucks, cement mixers, and box trucks used by moving companies or retailers. You can also tow a trailer if the trailer weighs less than 10,000 pounds and the combination does not exceed your vehicle's towing capacity.

You cannot drive a Class A vehicle, which is a tractor pulling a trailer weighing 10,001 pounds or more. You also cannot operate a Class C vehicle, such as a passenger van carrying 16 or more people (including the driver) or a small hazmat truck. If you need to haul heavy trailers or transport large groups of passengers, you will need a different class of CDL.

Some states allow endorsements that expand what you can do with your Class B license. Common endorsements include Hazmat (hazardous materials), Tanker (liquid cargo), and Passenger (for certain multi-passenger vehicles). You must pass an additional written test for each endorsement you want to add.

How to obtain a Class B license

The first step is to hold a regular driver's license for the minimum period your state requires — usually one year, though some states allow as little as 30 days. You will also need to pass a medical examination by a certified medical examiner and obtain a Medical Certificate, which your state's motor vehicle office will keep on file.

Next, you must pass a written knowledge test covering vehicle operation, safety, and road rules specific to commercial driving. The test is usually 50 questions, and you need to score at least 80 percent to pass. Study materials are available from your state's motor vehicle office or online.

After passing the written test, you must pass a skills test, which has three parts: a pre-trip vehicle inspection (you walk around the truck and point out safety features), a basic control skills test (you maneuver the vehicle in a closed course), and a road test (you drive on public roads with an examiner). You must pass all three parts on the same day or you will need to retake the entire skills test.

Some states allow you to take the skills test in a vehicle you own or have access to; others require you to use a state-approved testing vehicle. Check your state's requirements before you schedule your test.

Medical requirements and disqualifying conditions

You must pass a medical examination by a certified medical examiner listed on the National Registry of Certified Medical Examiners. The examiner checks your vision, hearing, blood pressure, and overall health. You will also be asked about any medications you take and any medical conditions you have.

Certain conditions disqualify you from holding a CDL, including uncontrolled diabetes, heart disease, a history of seizures, and severe sleep apnea. Other conditions may disqualify you temporarily — for example, if you recently had surgery or are taking certain medications. If you have a medical condition you are unsure about, contact your state's motor vehicle office before you schedule an exam.

Your Medical Certificate is valid for up to two years. You must renew it before it expires, or your CDL will become invalid. Some states send renewal reminders; others do not, so mark the expiration date on your calendar.

Renewal, validity period, and record checks

A Class B license is valid for four or eight years depending on your state. You must renew it in person at your state's motor vehicle office — you cannot renew online or by mail. When you renew, you must pass the written knowledge test again and provide an updated Medical Certificate.

Your state will also check your driving record for violations, accidents, and disqualifying events. If you have been convicted of certain crimes (such as drug trafficking) or have accumulated too many violations, your CDL may be suspended or revoked. A single serious violation — such as reckless driving, improper lane change, or following too closely — can result in a 60-day disqualification. Two serious violations within three years result in a 120-day disqualification, and three within three years result in permanent disqualification.

Some violations, such as driving under the influence or leaving the scene of an accident, result in automatic disqualification for at least one year on a first offense.

Differences between Class B and other CDL classes

The three main CDL classes are A, B, and C. A Class A license covers any combination of vehicles where the towed unit weighs 10,001 pounds or more — typically a tractor pulling a heavy trailer. Class A is the highest tier and allows you to drive Class B and Class C vehicles as well. A Class C license covers vehicles that do not fit Class A or B but are still commercial — usually small hazmat trucks or passenger vans carrying 16 or more people.

Class B is the middle tier. It covers heavier single vehicles than Class C but does not allow you to pull heavy trailers like Class A does. If you drive a delivery truck or garbage truck, Class B is likely what you need. If you drive a tractor-trailer rig, you need Class A. If you drive a small hazmat vehicle or a passenger van, you need Class C.

Penalties for violations and what happens if you lose your license

Violations on a commercial license carry harsher penalties than violations on a regular license. A single speeding ticket, improper lane change, or other moving violation can result in points on your record and fines. Accumulating too many points in a short period can trigger a suspension or disqualification.

If your CDL is suspended or revoked, you cannot legally drive any commercial vehicle. If you are caught driving commercially without a valid CDL, you face criminal charges, fines up to several thousand dollars, and possible jail time. You also cannot drive a regular vehicle during a CDL suspension in some states — check your state's rules.

If you lose your CDL due to a violation or medical issue, you may be able to reinstate it after a waiting period. The process varies by state and by reason for disqualification. Contact your state's motor vehicle office for details on reinstatement.

Frequently Asked Questions

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

Only if the pickup truck has a GVWR over 26,000 pounds. Most standard pickup trucks weigh less than that and can be driven with a regular driver's license. Check your vehicle's registration or owner's manual for the GVWR.

Can I get a Class B license if I have a DUI on my record?

A DUI conviction does not automatically disqualify you, but it will be reviewed during your process. Some states may deny your process or require a waiting period. Contact your state's motor vehicle office to find out how a DUI affects your specific situation.

How much does it cost to get a Class B license?

Costs vary by state but typically range from $50 to $300 for the license itself, plus fees for the medical exam (usually $50 to $150) and any training courses you take. Some employers cover these costs for new hires.

What happens if I fail the skills test?

You can retake the test, but you must pay the testing fee again. Most people pass on the second or third attempt. Some states allow you to retake the test the same day; others require you to wait a few days or weeks between attempts.

Can I drive a Class B vehicle with a regular driver's license?

No. Any vehicle with a GVWR over 26,000 pounds requires a CDL. Driving one without a CDL is illegal and can result in fines and criminal charges, even if you have a regular driver's license.
