The minimum requirement: a commercial driver's license and a training program
To drive a commercial truck legally in the United States, you need a Commercial Driver's License (CDL) issued by your state. Getting one requires passing a written test on traffic laws and truck-specific rules, a pre-trip inspection test, and a road test in an actual truck. Before you can take those tests, most states require you to hold a regular driver's license and pass a medical exam.
You do not need a four-year degree or any formal education beyond high school to get a CDL. However, you do need training — either through a formal truck driving school or through an apprenticeship with a trucking company. The training teaches you how to operate an 18-wheeler, how to handle cargo, how to inspect your vehicle for safety problems, and how to follow hours-of-service rules that limit how long you can drive without rest.
Most people complete this training in 4 to 8 weeks at a dedicated truck driving school, though some companies run longer programs or offer on-the-job training that stretches over several months. The cost ranges widely depending on the school and program length — typically between $3,000 and $15,000 — though some trucking companies will pay for your training in exchange for a commitment to work for them after you finish.
Key Takeaways
- A Commercial Driver's License (CDL) is the only legal requirement, and you can get one without a college degree or high school diploma if you pass the required tests.
- Truck driving schools typically take 4 to 8 weeks and cost $3,000 to $15,000, though some trucking companies will cover the cost if you agree to work for them afterward.
- The CDL test includes a written exam on regulations, a pre-trip inspection test, and a road test in a commercial truck — you cannot pass by studying alone.
- Some states and companies require additional endorsements (like hazmat certification) depending on what cargo you will haul, which adds time and cost to your training.
What happens at truck driving school
A typical truck driving school combines classroom instruction with hands-on driving practice. In the classroom, you learn federal and state traffic laws, vehicle maintenance, cargo securement, weight and balance rules, and the hours-of-service regulations that govern how long you can drive without a break. You also study the pre-trip inspection — a detailed walk-around check of your truck that you must perform before every shift and demonstrate on your CDL road test.
The driving portion happens in the school's trucks, usually with an instructor in the passenger seat. You practice basic maneuvers like backing up, turning, and parking in tight spaces. You drive on highways and in city traffic. You learn how to handle a fully loaded trailer, which behaves very differently from an empty one. Most schools require you to log a minimum number of hours behind the wheel — often 120 to 160 hours — before you are ready to take your CDL test.
Some schools offer additional training beyond the CDL basics. You might take courses on defensive driving, fuel efficiency, or specific cargo types like hazardous materials. These add to both the time and cost of your program, but they can make you more competitive when you start looking for a job.
Company-sponsored training and apprenticeships
Many large trucking companies run their own training programs and will hire you before you have your CDL, then train you and pay for your license test. These programs typically last 3 to 6 weeks and are free to you, though you usually sign a contract agreeing to work for that company for a set period — often 1 to 2 years — after you finish. If you leave before the contract ends, you may have to repay part or all of the training cost.
Company training is often faster and cheaper than independent truck driving school, and you start earning a wage during training at some companies. The trade-off is less flexibility: you are locked into working for one employer, and the training curriculum is designed around that company's needs and equipment rather than giving you broad knowledge of the industry.
A few companies offer formal apprenticeships registered with the Department of Labor, which combine classroom instruction with paid on-the-job training over a longer period — sometimes 6 months to a year. These are less common than company training programs but can provide more structured learning and clearer wage progression.
State-specific requirements and endorsements
Every state administers its own CDL test, and the written portion varies slightly by state. Some states test more heavily on specific regulations or local road conditions. You must take the test in the state where you hold a regular driver's license, though once you pass, you can drive commercially in any state.
Depending on what you will haul, you may need additional endorsements on your CDL. A hazmat endorsement is required if you transport hazardous materials like fuel or chemicals — it requires passing an extra written test and a background check. A tanker endorsement is needed for liquid cargo. A passenger endorsement applies if you drive a bus. Each endorsement adds a test fee and study time, typically a few hours to a few days of preparation.
Some states also require a medical certificate from a Department of Transportation-approved doctor before you can take your CDL test. This exam checks your vision, hearing, blood pressure, and other health factors. The cost is usually $100 to $200, and you will need to renew it every 1 to 2 years depending on your health status.
High school diploma or GED requirements
Most truck driving schools do not require a high school diploma or GED to enroll, though some do. If a school requires one and you do not have it, you can still pursue trucking by finding a company-sponsored program that does not have that requirement, or by getting your GED first. The GED typically takes a few weeks to a few months to complete, depending on your starting point and how much time you can dedicate to studying.
Some trucking companies prefer to hire drivers with a high school diploma or GED, viewing it as a sign of reliability and basic literacy. However, many large carriers will hire without one if you pass the CDL test and pass their background check. Smaller companies and owner-operators are often more flexible on this requirement.
If you are considering trucking as a career path and do not have a diploma, getting your GED before you start truck driving school can make you more competitive for better-paying jobs and may open doors to advancement into dispatch, training, or management roles later.
Continuing education and skills beyond the CDL
Once you have your CDL, you are legally allowed to drive a truck. However, the trucking industry values additional skills and training. Defensive driving courses teach techniques to avoid accidents and can lower your insurance costs. Fuel efficiency training helps you save money on gas and makes you more attractive to employers. Some drivers pursue training in specialized cargo handling, like flatbed loading or refrigerated transport, which can lead to higher-paying jobs.
Professional development is ongoing in trucking. You may attend safety seminars, take refresher courses on regulations, or pursue training in new equipment or technology. Some companies offer tuition reimbursement for drivers who complete additional training. Unlike many careers, trucking does not require a degree to advance, but continuous learning can improve your earning potential and job security.
The cost breakdown and financing options
If you attend an independent truck driving school, expect to pay $3,000 to $15,000 depending on program length and location. Some schools offer payment plans, allowing you to pay in installments. A few offer financing through third-party lenders, though interest rates can be high. Some states and local workforce development agencies offer grants or subsidies for truck driving training, particularly if you are unemployed or underemployed — contact your state's Department of Labor or a local workforce center to ask what is available in your area.
If you go through company-sponsored training, the training itself is free, but you are committing your labor for a set period. Calculate whether the wage you will earn during that commitment period makes up for the cost you would have paid at an independent school. Some drivers find this a good deal; others prefer the independence of paying for their own training.
The CDL test fee varies by state but typically costs $50 to $150. Medical exams run $100 to $200. Endorsement tests add $10 to $50 each. These are one-time costs, though your medical certificate will need renewal periodically.
Frequently Asked Questions
Do I need a college degree to become a truck driver?
No. A Commercial Driver's License is the only credential required by law. You do not need any college education, though a high school diploma or GED can make you more competitive for certain jobs and advancement opportunities.
Can I get a CDL without going to truck driving school?
Technically yes — you can study on your own and take the CDL test. However, most states and the CDL test itself assume you have received formal training on vehicle operation, safety inspection, and regulations. Passing without training is extremely difficult. Company-sponsored training is a practical alternative to independent truck driving school.
How long does it take to get a CDL from start to finish?
If you already have a regular driver's license and pass your medical exam, a truck driving school typically takes 4 to 8 weeks. Company-sponsored training can be 3 to 6 weeks. Add 1 to 2 weeks for scheduling your CDL test and receiving your license after you pass. Total time is usually 1 to 3 months.
What if I fail the CDL road test?
You can retake it. Most states allow you to test again within a few days or weeks, though you may have to pay the test fee again. If you fail multiple times, your truck driving school or company trainer can provide additional instruction before your next attempt. Failing is common — many people need two or three tries to pass.
Do I need special training to haul hazardous materials?
Yes. A hazmat endorsement requires passing an additional written test and a background check. The test covers regulations specific to hazardous cargo. Most truck driving schools offer hazmat training as an add-on course that takes a few days and costs $200 to $500 extra. You do not need hazmat training to get your basic CDL, only if you want to haul that cargo.
