Thinking about getting your Commercial Driver’s License (CDL)? That’s the first big step toward starting your trucking career. But one question most new drivers ask is — how long does it actually take to get a CDL?
The truth is, it depends. The type of CDL you need, the training school you choose, and the time you can put into practice all play a part.
In most cases, you’ll go through classroom lessons, pass a written test, complete behind-the-wheel training, and take a driving exam. For most drivers, the whole process takes anywhere from a few weeks to a few months.
In this guide, we’ll break it all down so you know exactly what to expect and how to plan your path to becoming a licensed truck driver.
How long does it take to get a CDL?
The time it takes to earn your Commercial Driver’s License (CDL) can range from seven weeks to as long as six months, depending on your schedule and training path. In most cases, drivers who enroll in a full-time CDL training program can complete the process in about seven weeks.
However, this timeline isn’t the same for everyone. The overall duration can be shorter or longer based on several factors, such as the type of CDL you’re pursuing, your training availability, and how quickly you progress through the required coursework and behind-the-wheel practice.
8 factors that affect the time frame for obtaining a CDL
The time it takes to obtain a Commercial Driver’s License (CDL) can range widely, from as short as three weeks to as long as six months. For those enrolled in a full-time driver training program, the average timeframe is around seven weeks.
Several factors can influence this timeline, which we’ll outline below.
1. The type of CDL
The time it takes to earn your CDL largely depends on which class of license you’re aiming for. There are three main types:
- Class A CDL: Required for operating combination vehicles, such as tractor-trailers and semi-trucks.
- Class B CDL: Needed for driving straight trucks, box trucks, and large buses.
- Class C CDL: Necessary for smaller vehicles carrying passengers or hazardous materials.
Each CDL class authorizes you to operate vehicles with different weight capacities and cargo types, including those that may involve hazardous materials. Generally, Class A CDL programs take the longest, as they involve more advanced driving skills and vehicle handling. Class B and Class C licenses usually have shorter training timelines.
If your goal is to become a professional truck driver, deciding whether you need a Class A, B, or C CDL is the first step in determining your training path and overall timeline.
2. CDL endorsements you choose
Adding endorsements to your CDL can extend your training time because each one requires additional instruction and testing. Six main endorsements can be added to a CDL:
- P: Passenger Transport
- S: School Bus/Passenger Combo
- T: Double/Triple Trailers
- N: Tank Vehicles (Tanker)
- H: Hazardous Materials (HAZMAT)
- X: Tanker and HAZMAT Combo
Although endorsements aren’t necessary for all driving positions, they expand your career options, allowing you to qualify for specialized trucking roles and often command higher pay.
3. Interstate vs. intrastate driving
The type of driving impacts how long it takes to obtain a CDL. Requirements vary by state: in some cases, drivers who operate only within their state (intrastate) may not need a CDL, depending on the vehicle’s weight and type. In other states, intrastate drivers must meet the same standards as interstate drivers, including completing the training and passing exams.
If your goal is to drive solely within your state, you may have fewer licensing requirements. However, to drive across state lines (interstate driving), you must comply with federal regulations and obtain a valid CDL, regardless of your state’s rules. This distinction can influence the time and effort required to become a licensed commercial driver.
4. Full-time vs. part-time CDL training
Completing a CDL requires enrolling in a formal training program, which is usually offered through trucking schools or community colleges. The duration of CDL school depends largely on whether you choose a full-time or part-time program.
Training programs generally follow two types of schedules:
Part-time program:
Part-time CDL programs are often scheduled on weekends, such as Saturdays and Sundays, and their duration can vary depending on the school. These programs are ideal for individuals who work full-time or cannot commit to a weekday training schedule, providing a more flexible path to earning a CDL.
Full-time program:
Full-time CDL programs typically run five days a week (Monday through Friday) and last around five weeks. If you’re wondering how to get a CDL quickly, a full-time CDL training program is the way to go.
5. Classroom instruction vs. hands-on training
The balance between classroom learning and practical driving experience varies depending on the CDL program you choose. On average, students spend about one-third of their time in the classroom covering theory, rules, and safety, while the remaining time is dedicated to hands-on practice in the yard and on the road.
When selecting a program, think about your learning style:
- Do you learn best through instruction and lectures in a classroom setting?
- Or do you prefer hands-on, practical experience behind the wheel?
Classroom training
Most CDL programs include between 30 to 80 hours of classroom instruction, though the exact number varies depending on the school and program type.
During this time, students learn the fundamental knowledge required to operate commercial vehicles safely and legally. The course typically covers traffic laws, safety regulations, vehicle inspection procedures, basic mechanics, and industry best practices. Programs with more intensive classroom instruction may take longer but provide a stronger foundation for the written and skills tests.
While more classroom time may extend the overall duration of the program, it also ensures that you have a solid foundation before moving on to hands-on driving practice, making it a critical part of CDL training.
Driving or practical training
The number of driving hours required is another key factor in determining how long it takes to get a CDL. Many programs require students to complete a set number of supervised driving hours with a licensed CDL instructor. These hours allow learners to gain practical experience operating commercial vehicles in a variety of conditions, including city streets, highways, and parking lots.
Programs that demand more driving hours help students become more confident and skilled behind the wheel, which not only improves safety but also increases the likelihood of passing the CDL skills test on the first attempt. While programs with extended driving practice may take longer to complete, the hands-on experience is invaluable for building competence and readiness for a professional driving career.
6. Scheduling your CDL test
After starting your CDL training, you’ll likely be eager to schedule your CDL exam and begin your career as a professional driver. However, most states require new drivers with a Commercial Learner’s Permit (CLP) to wait at least 14 days before taking the CDL test.
CDL tests are usually scheduled through your local Department of Motor Vehicles (DMV). Each state sets its own rules and timelines, with many requiring appointments to be made at least 48 hours in advance. Be sure to check your state DMV website for the exact steps and requirements to schedule and complete your CDL exam.
7. Type of truck – Manual vs. Automatic transmission
The type of truck you train on can influence how quickly you acquire the necessary driving skills. Learning to operate a manual transmission truck typically takes longer because it requires mastering gear shifting, clutch control, and engine braking.
In contrast, automatic transmission trucks are generally easier to learn, allowing students to focus more on maneuvering, traffic navigation, and safety procedures rather than shifting gears.
Choosing the type of truck that aligns with your comfort level and career goals can impact your overall training duration. While training on a manual truck may take extra time, it can also increase your versatility as a driver, since many commercial trucks, especially tractor-trailers, still use manual transmissions.
8. Military experience
Having prior military driving experience can significantly shorten the time it takes to obtain a CDL. The FMCSA allows veterans with qualifying military driving experience to waive the CDL skills test in many cases. This means they can bypass the behind-the-wheel portion of training, moving more quickly through the licensing process.
Military-trained drivers often already possess valuable skills such as operating large vehicles, following safety protocols, and navigating challenging driving conditions. As a result, veterans may require less additional instruction, allowing them to enter the commercial driving workforce faster than those without prior experience.
9. Student’s driving ability
A student’s individual driving skills and aptitude play a major role in determining how quickly they can obtain a CDL. Learners who quickly grasp vehicle handling, road rules, and safety procedures are more likely to pass the skills test on their first attempt, reducing the overall time required to complete the licensing process.
Conversely, students who need extra practice to develop confidence or correct mistakes may require additional training hours and potentially retake portions of the driving exam. Strong coordination, focus, and adaptability behind the wheel can therefore have a direct impact on how fast a student progresses through CDL training.
How much does it cost to get a CDL license?
On average, aspiring drivers can expect to spend between $4,000 and $12,000 to become fully licensed and professionally trained, covering all training, testing, and licensing fees.
The total cost varies depending on your state and the training program you choose. Each state sets its own fees for CDL applications, testing, and endorsements. Additionally, new drivers must complete commercial motor vehicle (CMV) training through an approved provider, which can also impact the overall cost.
How to obtain a Commercial Driver’s License (CDL)?
Before applying for a Commercial Driver’s License (CDL), you must already hold a valid standard driver’s license. The CDL application process requires providing proof of identity and residency, passing a background check, completing a vision exam or medical evaluation, and successfully taking a knowledge test. Once you obtain a Commercial Learner’s Permit (CLP), there is usually a minimum holding period before you can take the full CDL road test.
During this time, many aspiring drivers enroll in CDL training programs, which can be online or in-person, and gain supervised driving experience with a licensed CDL driver. The overall timeline for earning your CDL can range from about two weeks (the minimum holding period) to six or seven months, depending on factors such as training format, prior driving experience, and the type of commercial vehicle you intend to operate.
Start Your Journey Toward a CDL Career
The timeline for obtaining a Commercial Driver’s License (CDL) varies depending on several factors, including the class of CDL you are pursuing, whether you choose full-time or part-time training, and the availability of testing appointments. Most new drivers can expect to complete the process in three to eight weeks, though it can take up to three months in some cases.
Additional factors, such as background checks, optional endorsements (like hazmat), and scheduling delays, can also extend the timeline. Full-time programs may allow you to earn your CDL in as little as 3–4 weeks, while part-time training or additional endorsements can push the process to several months.
On average, from meeting prerequisites and obtaining a Commercial Learner’s Permit (CLP) to completing training and passing the skills test, most aspiring drivers spend about one to two months preparing for and earning their CDL. By selecting the right training program and staying organized, you can efficiently navigate the process and start your career in commercial driving.
Frequently asked questions about how long it takes to get a CDL
How long does CDL training take?
The duration of CDL training varies depending on the type of program you choose. Full-time, accelerated programs can be completed in about three to four weeks, while part-time courses designed for students who work simultaneously may take around six months to finish.
Most standard CDL programs include:
- Approximately 40 hours of classroom instruction covering rules, safety, and vehicle operation
- Around 120 hours of hands-on driving practice on the road
In total, a typical CDL training program involves about 160 hours of combined instruction and practice.
If you plan to add endorsements—such as hazardous materials (hazmat) or passenger transport—expect additional training. These endorsements usually require an extra week of classroom study and a separate written exam to ensure you meet the necessary safety and regulatory standards.
How much driving practice is needed for a CDL test?
There is no federally mandated minimum number of driving hours required to take the CDL skills test. However, many training programs and employers recommend completing at least 160 hours of behind-the-wheel practice to gain sufficient experience and confidence.
Once you obtain a Commercial Learner’s Permit (CLP), you are allowed to practice driving under the supervision of a licensed CDL holder. This practice period helps you develop the skills necessary to handle large commercial vehicles safely and prepares you for the written and road skills exams.
How long is the CDL driving test?
The CDL driving test typically lasts between 90 minutes and two hours, while the written knowledge portion usually takes only one to two hours. During this time, an examiner assesses a driver’s ability to operate a commercial vehicle safely and efficiently. Key skills evaluated include backing maneuvers, emergency stops, three-point turns, and proper intersection approaches.
The road skills test is divided into three main components:
- Basic control skills test – Demonstrates your ability to handle the vehicle in controlled maneuvers.
- On-road driving test – Evaluates your performance in real-world traffic conditions.
- Vehicle inspection test – Ensures you can properly inspect your vehicle for safety and compliance before driving.
How often do you need to renew your CDL?
The renewal requirements for a CDL differ depending on the state. Generally, a CDL is valid for five to eight years, and most state Departments of Motor Vehicles (DMV) will send a reminder as your expiration date approaches.
In addition to routine renewals, you may need to update your CDL under certain circumstances, such as:
- Adding a new endorsement to your existing license (e.g., hazmat or passenger transport)
- Removing an air brake restriction
- Changing your federal driving classification, for example, moving from non-excepted interstate to excepted interstate status
- Upgrading your CDL class or group designation to operate different types of commercial vehicles
Do you have to take a class to get a CDL?
Technically, you do not need formal classroom training to obtain a CDL. However, many employers prefer candidates who have completed instruction at an accredited truck driving school, often due to insurance requirements. Completing a training program also signals to potential employers that you are serious about a career in commercial driving.
Attending a truck driving school provides essential knowledge and hands-on experience, helping you pass the CDL exams and prepare for a successful career on the road.
Truck driving training is offered at a variety of institutions, including:
- Community colleges and vocational schools
- Private truck driving schools
- Freight and trucking companies
- High schools with commercial driving programs
- Military programs for vehicle operation
Can you retake the CDL exam if you fail?
Failing your CDL exam isn’t the end of the road—you are allowed to retake the test. The rules for retakes vary by state, but in most cases, you can schedule another attempt at the next available testing date, often after a short waiting period of a few days.
Many states permit multiple retakes; however, there may be limits on how many times you can try within a specific period, such as three attempts before additional training or preparation is required. To avoid surprises, always review your state’s CDL retake policies so you know the exact requirements and waiting periods.
