To become a truck driver, you need a commercial driver’s license (CDL), usually a Class A for tractor-trailers. Federal rules require new drivers to complete entry-level driver training from a provider listed on the FMCSA Training Provider Registry before taking the CDL skills test. You must be at least 21 to drive across state lines (18 within most states) and pass a DOT medical exam.
What the job really looks like
- Long haul (over the road): days or weeks away from home, sleeping in the truck, crossing many states.
- Regional: a few nights out each week, home most weekends.
- Local: home every night, but often more loading, unloading and city traffic.
- Specialties: flatbed (securing loads yourself), tanker, refrigerated, car hauling and less-than-truckload freight.
Federal hours-of-service rules limit how long you can drive, and electronic logging devices track it. Expect long hours sitting, irregular sleep and real responsibility: an 80,000-pound vehicle demands full attention every minute.
Ways to get trained
- Private CDL schools: programs of several weeks that cover theory and behind-the-wheel training.
- Community college programs: sometimes longer, sometimes eligible for financial aid.
- Company-sponsored training: a carrier trains you at low or no upfront cost in exchange for a commitment to drive for them. Read the contract carefully, especially what you owe if you leave early.
- Apprenticeships: some carriers run registered apprenticeships that pair training with paid work.
- Military: motor transport roles provide experience, and some states streamline the CDL for veterans.
Whatever you choose, confirm the provider is on the FMCSA Training Provider Registry, or your training will not count toward the CDL.
Getting your CDL, step by step
- Pass a DOT medical exam with a listed medical examiner and get your medical card.
- Pass the state knowledge tests to get a commercial learner’s permit (CLP).
- Complete entry-level driver training, both theory and behind-the-wheel, with a registered provider.
- Hold your CLP for at least 14 days, then take the skills test: a vehicle inspection, basic control maneuvers and a road test.
- Add endorsements as needed, such as tanker, doubles and triples or hazardous materials. The hazmat endorsement requires a TSA security threat assessment.
- Expect drug and alcohol testing before you start and throughout your career.
Details and fees are set by your state, so check your state DMV or licensing agency.
Starting in high school
You cannot drive interstate until 21, so use the high school years well: keep a clean driving record, take any automotive or logistics classes, and get work experience in a warehouse or delivery job. After graduation, some young drivers start with local or intrastate work at 18. Our guides on building a career without a degree and helping a teen choose a career offer more context.
Test the lifestyle first
- Talk honestly with family about time away if you are considering long haul.
- Ask drivers for informational interviews about home time, sleep and what their first year was like.
- Try a non-CDL delivery or box truck job to see how you handle long days behind the wheel.
Who does well, and why drivers leave
Drivers who stay tend to be independent, calm under pressure, reliable and comfortable with solitude. The most common reasons people leave are time away from family, health strain from sitting and irregular sleep, and isolation. Many shift to local routes, and experienced drivers move into training, dispatch, safety roles or owning their own truck.
Driving as a second career
Truck driving is a common career change because training takes weeks, not years. Before you commit, get the DOT physical to confirm you qualify, and compare company-sponsored and paid training carefully. For current pay and outlook, check the Bureau of Labor Statistics Occupational Outlook Handbook.
Where a mentor helps
A mentor helps a young adult weigh trucking against other options, compare schools and contracts, stay on schedule through training and testing, and handle the first months on the job. Mentors are not credentialed career counselors, admissions counselors or licensing experts; the DMV and FMCSA set the rules. Learn about career and education mentoring and young adult mentoring.

Common questions
How old do you have to be to drive a truck?
Federal rules require drivers to be at least 21 to drive across state lines. Most states allow intrastate commercial driving at 18.
What is the difference between a Class A and Class B CDL?
A Class A covers combination vehicles such as tractor-trailers. A Class B covers heavy single vehicles like box trucks, dump trucks and many buses.
Is company-sponsored CDL training free?
It often has low upfront cost, but you usually agree to drive for that company for a set time. If you leave early, you may owe the training cost, so read the contract first.
How long does it take to get a CDL?
Many people finish training and testing in several weeks, though it depends on the program and your state. You must hold your learner’s permit at least 14 days before the skills test.
