To get a commercial learner's permit (CLP), you must be old enough, pass the CDL general knowledge test (plus any endorsement tests you want), hold a valid driver's license, and clear your state's identity, residency and medical-certification checks. The permit is valid for no more than one year, and you cannot take the CDL skills test until you've held it for 14 days. Details and fees vary by state, so confirm the specifics with your state's driver licensing agency. Facts below are as of October 2026.
What is a CLP and what can you do with it?
A CLP is the federal first step toward a Class A CDL. Under 49 CFR 383.25, it lets you practice driving a commercial vehicle on public roads, but only with a supervising CDL holder in the front seat next to you. That person must hold the proper CDL class and any endorsements needed for the vehicle, and must be able to observe and supervise you directly.
A CLP is not a license to drive alone. You also cannot haul hazardous materials on a CLP, and tank-vehicle permit holders may only drive empty tanks (or tanks that have been purged of hazmat).
What are the requirements to get a CLP?
The federal baseline is in 49 CFR 383.71. States add their own paperwork and fees, but you can expect to need the following:
- Age. At least 18 to get the permit. Federal rules generally require you to be 21 to drive a commercial vehicle across state lines, so drivers aiming for interstate OTR work should plan around that.
- A valid regular driver's license from your state, plus proof of identity and proof you live in that state (a government-issued tax form or similar document with your name and address).
- Medical certification. If you will drive in non-excepted interstate commerce, which describes most OTR drivers, you need a DOT medical exam from a certified medical examiner and your state needs the result on file. Read more in our driver guides on DOT physicals.
- Self-certification. You tell the state which kind of driving you will do (interstate or intrastate, excepted or non-excepted). Pick the one that matches the job you want.
- A passing knowledge test score for your CDL class, plus any endorsement tests you want to add now.
- A clean Clearinghouse check. States must query the FMCSA Drug and Alcohol Clearinghouse and cannot issue a permit if you are prohibited from performing safety-sensitive functions (49 CFR 383.73). States also check your driving record.
Non-domiciled permits: an FMCSA final rule that took effect March 16, 2026 sharply narrowed who can get a non-domiciled CLP or CDL (the issuing state is not where you are domiciled). If that could apply to you, read the Federal Register notice and ask your state agency what documents it accepts.
How do you get a CLP step by step?
- Get your DOT medical card if you'll drive interstate, and keep a copy.
- Download your state's CDL manual from the licensing agency's site. The tests are written from it.
- Study the sections for your class. For Class A, that means general knowledge, air brakes if the truck has them, and combination vehicles. Add endorsement sections (tanker, doubles/triples, hazmat) only if you plan to test for them.
- Gather your documents: current license, proof of identity, proof of residency, Social Security information, and your medical certificate.
- Book or walk in at your state licensing office. Some states require an appointment for commercial tests; many publish test-site hours online.
- Pass the knowledge test(s), pay the fee, and receive your permit.
- Start your required training with a school listed on the FMCSA Training Provider Registry (see below), and keep practicing behind the wheel with a qualified CDL holder.
What is on the CLP knowledge tests?
All states use tests that meet federal standards, but the questions and passing score come from your state. The general knowledge test covers safe driving, vehicle controls, cargo, and inspection basics. If you're going Class A, expect air brakes and combination vehicle sections too. For prep ideas, see our complete guide to getting your CDL. Check your state manual for the passing score and number of questions rather than relying on a number from the internet.
How does ELDT fit in with the permit?
Since February 7, 2022, first-time Class A and Class B CDL applicants, people upgrading to A or B, and first-time applicants for the passenger, school bus or hazmat endorsements must complete Entry-Level Driver Training from a provider on the FMCSA Training Provider Registry before testing (49 CFR Part 380, Subpart F). For a Class A CDL, the practical order is:
- Pass the permit knowledge test and get your CLP.
- Complete theory and behind-the-wheel (range and road) training with a registered provider.
- Take the CDL skills test after the 14-day waiting period and after your training is on record.
We cover this in detail in What Is ELDT? and the cost side in How Much Does CDL Training Cost?.
How long is a CLP valid, and what is the 14-day rule?
A CLP is valid for no more than one year from the date it was first issued, and a shorter-term permit may be renewed only as long as the total stays within that one year (49 CFR 383.25). Federal rules also bar you from taking the CDL skills test during the first 14 days after the permit is first issued. If your permit expires before you pass, you'll likely need to start the process again, so plan your training timeline.
Worked example (hypothetical)
Say a new driver passes the knowledge tests on October 5. The 14-day waiting period ends October 19, so the earliest possible skills test date is after that. If their ELDT theory and behind-the-wheel training aren't complete by then, they can't test yet. Suppose their training takes five weeks; they could test in mid-November, leaving about 11 months of permit validity as a cushion for a retake. The numbers are illustrative; your school's schedule and your state's testing availability will set the real dates.
Common mistakes to avoid
- Skipping the medical card and finding out at the counter that your state needs it on file.
- Studying a different state's manual. Use the manual from the state issuing your permit.
- Choosing a training provider that isn't on the Training Provider Registry. Training from an unlisted provider won't count toward ELDT.
- Letting the permit run out. One year goes faster than it sounds if you wait on school openings.
- Practicing with the wrong person. The supervising driver must hold the right CDL class and endorsements, and sit in the front seat.
- Adding every endorsement at once. Extra tests can mean extra fees and retakes. Add what the job needs.
Frequently asked questions
Can I drive a semi alone with a CLP?
No. Federal rules require a qualified CDL holder in the front seat next to you at all times.
How much does a CLP cost?
Fees are set by each state and often include separate charges for the knowledge test and permit issuance. Check your state licensing agency's fee schedule.
Do I need ELDT before I take the permit test?
For a Class A or B CLP, the training is required before the skills test, not before the general knowledge test. Hazmat, passenger and school bus endorsements have their own ELDT requirements, so ask your state how it sequences them.
Can I use a permit from one state in another?
Generally not for driving a commercial vehicle in another state. Take your tests in the state where you live.
What if I fail the knowledge test?
States set their own retake rules, waiting periods and fees. Ask the testing office before you leave.
