What Class B training teaches you
Class B training prepares you to drive vehicles heavier than a standard car but smaller than a full commercial truck — typically vehicles between 10,001 and 26,000 pounds gross vehicle weight rating (GVWR). The training covers how these larger vehicles handle differently: they need more stopping distance, have bigger blind spots, and respond differently to steering and braking than a passenger car.
The course teaches you the mechanical systems specific to these vehicles, including air brakes (which work differently from hydraulic brakes), engine operation, and cargo securement. You will also learn federal and state rules about hours of service, logbooks, and vehicle inspection procedures. Most programs include both classroom instruction and behind-the-wheel practice.
Class B training is required in most states before you can take the Class B written test and road test at the Department of Motor Vehicles. Some states allow you to study on your own and skip formal training, but most require it or strongly recommend it because the test failure rate is high without it.
Key Takeaways
- Class B training teaches you to operate vehicles weighing 10,001 to 26,000 pounds, including how air brakes and larger steering systems work differently than a car.
- Most states require formal training before you can take the Class B written and road tests, though a few allow self-study.
- Training typically takes two to four weeks depending on whether you attend full-time or part-time, and costs between $3,000 and $7,000 depending on the school and your state.
- You will need a valid driver's license, a medical certificate from a Department of Transportation-approved doctor, and a Social Security number to start training.
- After training, you must pass a written knowledge test, a pre-trip vehicle inspection test, and a behind-the-wheel road test to receive your Class B license.
How long training takes and what it costs
Most Class B training programs run four weeks full-time, meeting five days a week for six to eight hours per day. Some schools offer part-time or evening options that stretch across eight to twelve weeks. The length depends on how many hours your state requires — this varies from 160 to 240 hours depending on whether your state mandates classroom time, behind-the-wheel hours, or both.
Tuition ranges widely by location and school type. Private truck driving schools typically charge $3,500 to $7,000 for a full Class B program. Community colleges in some states offer Class B training at lower cost, sometimes $2,000 to $4,000, but availability is limited to certain regions. Some employers who hire Class B drivers will pay for training if you commit to working for them after you finish, though this is less common than it is for Class A (full commercial truck) training.
You should ask any school you contact whether the tuition covers the written test and road test fees, or whether those are separate. Some schools bundle everything; others charge $100 to $300 extra for testing.
What you need before you start
You must have a valid driver's license from your state before you enroll. Most schools will not accept a learner's permit or an expired license. You also need a Social Security number and proof of legal residency or citizenship — bring your birth certificate, passport, or state ID.
You will need a Department of Transportation (DOT) medical certificate before you can take the road test. This is not the same as a regular doctor's visit. You must see a DOT-certified medical examiner, who will check your vision, hearing, blood pressure, and ability to operate a vehicle safely. The exam costs $50 to $150 depending on the provider. Many training schools can refer you to an examiner or can tell you where to find one in your area. You do not need the medical certificate to start training, but you will need it before the DMV road test.
Bring your Social Security card, proof of address (a utility bill or lease), and your current driver's license to your first day of class. Different schools have slightly different document requirements, so call ahead and ask what to bring.
What happens in the classroom and behind the wheel
Classroom time covers federal motor carrier safety regulations, vehicle systems (engine, transmission, brakes, steering), cargo handling and weight distribution, and how to inspect a vehicle before driving. You will learn to read gauges, understand tire pressure and load limits, and recognize when a vehicle is unsafe to operate. Most programs also teach basic maintenance so you can spot problems early.
Behind-the-wheel training usually starts in the second or third week. You will practice in an actual Class B vehicle, often a straight truck or small dump truck, in a controlled environment first — an empty lot or quiet roads — before moving to busier streets. You will practice backing up, which is one of the hardest skills for new Class B drivers because the vehicle is longer and the blind spots are larger. Most programs require 40 to 80 hours of behind-the-wheel time, split between instructor-led driving and supervised practice.
By the end of training, you should be able to perform a pre-trip inspection from memory, operate the vehicle smoothly in various traffic conditions, and understand when you are within legal limits for hours of service and cargo weight.
The tests you take after training
After you finish training, you will take three separate tests through your state's Department of Motor Vehicles. The first is a written knowledge test covering federal regulations, vehicle systems, and safe driving practices. Most states allow you to take this test at a DMV office or testing center. The test typically has 50 to 100 questions and you must score at least 80 percent to pass.
The second test is a pre-trip vehicle inspection test. You will walk around a Class B vehicle and point out or demonstrate safety checks — tire condition, brake function, lights, mirrors, and fluid levels. This test is usually pass-or-fail based on whether you catch major safety problems. It takes 15 to 30 minutes.
The third test is the behind-the-wheel road test, which lasts 30 to 45 minutes. A DMV examiner rides with you while you drive a Class B vehicle through city streets, highways, and parking situations. You will be tested on smooth acceleration and braking, proper lane changes, backing up, and following traffic laws. You must pass all three tests to receive your Class B license.
Differences between Class B and other license classes
Class B is for vehicles heavier than a standard car but lighter than a full commercial truck. Class A is for the largest commercial trucks (over 26,000 pounds) and requires additional training because those vehicles are more complex and harder to control. Class C is a standard passenger vehicle license. Some states also have Class D for small commercial vehicles or Class E for motorcycles.
Class B training is shorter and less expensive than Class A training because Class B vehicles are smaller and the regulations are less complex. However, Class B still requires formal training in most states, whereas Class C does not. If you already have a Class C license, you do not need to retake the written test for basic traffic laws — you only take the Class B-specific written test, the pre-trip inspection test, and the road test.
What to expect after you get your license
Once you pass all three tests and receive your Class B license, you can legally operate Class B vehicles. Your license will show the class and any restrictions (for example, some states restrict certain endorsements or limit the types of cargo you can carry). You will need to renew your Class B license every four to eight years depending on your state, and you will need to renew your DOT medical certificate every two years (or one year if you are over 65).
Many employers require additional training beyond the state license — for example, defensive driving courses, specific vehicle training for the type of truck they use, or safety certifications. Some states also require a Class B license holder to maintain a logbook if they drive for hire, even though logbooks are more commonly associated with Class A drivers.
Frequently Asked Questions
Do I have to go to a training school, or can I study on my own?
Most states require formal training before you can take the Class B road test, but a few allow self-study. Check your state's Department of Motor Vehicles website to see whether training is mandatory in your state. Even where it is not required, most people who study alone fail the road test because Class B vehicles are difficult to operate without hands-on practice.
How much does the DOT medical exam cost?
A DOT medical exam typically costs $50 to $150 depending on the provider and your location. Some providers charge more if you have health conditions that require additional testing. Your training school can usually refer you to an examiner, or you can search the National Registry of Certified Medical Examiners on the Federal Motor Carrier Safety Administration website.
What if I fail the road test?
You can retake the road test after a waiting period, which varies by state but is usually one to two weeks. You will pay the test fee again. Most people pass on the second or third attempt. If you fail multiple times, consider taking a refresher course with your training school before trying again.
Can I get a Class B license if I have a suspended or revoked license?
No. You must have a valid, unrestricted driver's license to start Class B training. If your license is suspended or revoked, you must restore it first. Contact your state's Department of Motor Vehicles to find out what steps are required.
Do I need a Class B license to drive a large van or SUV?
No. A Class B license is only for vehicles over 10,001 pounds GVWR. Most vans and SUVs fall under 10,001 pounds and can be driven with a standard Class C license. Check the vehicle's registration or owner's manual to find its GVWR if you are unsure.
