General CDL Eligibility Requirements
Before you schedule your written test and road test, confirm you meet the basic age, residency, medical, and document requirements — so you don't discover missing paperwork at the DMV counter and make a wasted trip.
Six Core Requirements at a Glance
These are the basic requirements every CDL applicant must meet, regardless of which class of license you're applying for — none can be skipped.
Age Requirement
The minimum age to apply for a CLP/CDL is 18. Drivers engaged in interstate commerce, or transporting hazardous materials or hazardous waste, must be at least 21.
California Residency
You must be a California resident before applying, and must submit a proof-of-residency document — matching the address on your application — for original applications, renewals, transfers, and upgrades.
Proof of Legal Status
You must provide documentation proving your true name and legal presence. If your name doesn't match your application, you'll also need to submit an additional true-name document.
Federal Medical Certification
Your physical exam must be completed by a doctor listed on the National Registry of Certified Medical Examiners, and you must submit a valid original or copy of your MER/MEC form.
Social Security Verification
You must provide proof of your Social Security number, which the DMV verifies in real time against Social Security Administration records; original CDL applications only accept the physical Social Security card.
Disclosure of Prior License History
You must disclose every state where you've held a license in the past 10 years, and surrender any licenses from other states in your name — while confirming you don't hold more than one commercial driver's license.
Documents to Bring to the DMV Counter
We recommend printing this checklist and reviewing each item before heading to the DMV, to minimize repeat visits.
Commercial Driver's License Application (DL 44C / eDL 44C)
Can be filled out online ahead of time. Signing this form means you consent to a chemical test for alcohol or drug content if requested by law enforcement.
Proof of Identity and Legal Presence
Must be a certified copy of the original document, bearing an original seal or embossment — the DMV does not accept photocopies of copies.
Proof of Residency
Used to verify your California residency; the address must exactly match the residential address on your application.
Proof of Social Security Number
For original CDL applications, the physical Social Security card is the only accepted form of proof.
Medical Examination Report (MER) and Medical Examiner's Certificate (MEC)
Must be signed by a Nationally Registered Certified Medical Examiner within the past 2 years; only the first 4 pages of the MER need to be submitted.
Certificate of Driving Skill (DL 170 ETP, if applicable)
If your employer is DMV-authorized to self-certify, this certificate must be signed jointly by you and your employer.
10-Year Commercial Driving Employment History (for job applicants)
If applying for a commercial driving position, you must provide your employer with your commercial driving employment history for the past 10 years.
Application Fee
Valid for 12 months after payment; the CLP is valid for up to 180 days and can be renewed once, not to exceed 1 year total from your initial application date.
What Do I Need Before I Can Get a CLP (Commercial Learner's Permit)?
Before formally applying for a CDL, most applicants must first obtain a Commercial Learner's Permit (CLP). To get a CLP, you must meet the following:
- You must be at least 18 years old.
- You must already hold a valid California driver's license that allows you to drive at least a non-commercial Class C vehicle; a temporary license is also accepted.
- The CLP is only valid when presented together with the holder's own valid driver's license.
- While holding a CLP, you may only add the Tank (N), Passenger (P), and School Bus (S) endorsements.
- Holders of the "N" endorsement may not drive a tank vehicle unless the tank is empty and has been purged.
- Holders of the "P" or "S" endorsement may not carry passengers other than federal/state auditors, examiners, other trainees, or an accompanying licensed driver.
- After obtaining a CLP, you must wait at least 14 days before taking the skills test; this same waiting period applies when upgrading a vehicle class or changing endorsements/restrictions.
2026 Application Fee Schedule

| Original Application (with/without driving test) | $82 |
| Renewal | $48 |
| Skills / Driving Retest | $37 |
| Duplicate License | $36 |
| Name Change | $30 |
| Add Endorsement (except PV passenger endorsement) | $48 |
| Add Passenger Transportation Endorsement (PV) | $82 |
Are There Extra Age Requirements for Interstate Driving?
Yes. Applicants aged 18 to 20 may only engage in intrastate commerce — meaning the vehicle may not leave California for commercial purposes. Only drivers who are at least 21 years old may operate a commercial vehicle in interstate commerce, or transport hazardous materials or hazardous waste (whether intrastate or interstate). The DMV recommends that whenever interstate operation is even a possibility, applicants should apply for "Non-Excepted Interstate" (NI) status to avoid having to reapply later if their scope of operation changes.
Attempt Limits for the Knowledge and Skills Tests
Each application allows up to 3 attempts at the knowledge test, and the skills test (vehicle inspection, basic control, and driving test) as a whole also allows a maximum of 3 attempts combined. There is no mandatory waiting period after failing a knowledge test — you may retake it right away. However, failing any single component of the skills test counts toward the 3-attempt limit; for example, one failure each on the vehicle inspection, basic control, and driving test would use up all 3 attempts. If you need to take skills tests for different vehicle classes (such as Class A and a passenger vehicle), each class has its own separate 3-attempt limit.
Does the Federal ELDT Training Requirement Also Count as an Eligibility Requirement?
Yes. Since 2022, anyone applying for a Class A or Class B commercial driver's license for the first time, or adding a Passenger or School Bus endorsement for the first time, must complete a federally compliant Entry-Level Driver Training (ELDT) course before taking the DMV's behind-the-wheel driving test. Training hours and results must be uploaded directly to the federal database by an authorized training provider before the DMV will schedule your driving test.
What Situations Can Get an Application Denied?
Beyond the basic age, identity, and medical requirements, the following situations can also affect your eligibility:
- Holding an uncancelled driver's license from another state or country.
- Having your personal driving privilege revoked for an alcohol-, drug-, or felony-related violation, while still within the revocation period.
- Applying for a Hazmat endorsement but failing the TSA fingerprint background check, or being deemed a security risk.
- Having previously been found mentally incompetent or involuntarily committed for treatment, without obtaining a federal medical waiver.
Once You Meet the Requirements, Start Practicing the Knowledge Test
Having your documents ready is just the first step. Before heading to the DMV counter, we recommend testing yourself with our General Knowledge practice question bank to make sure you're also prepared for the written test — for a higher chance of passing on the first try.
Quick answers to the most common questions about CDL eligibility and document preparation.
Can I apply for a CDL directly without a regular California driver's license?
No. Applicants must first obtain a valid California non-commercial Class C driver's license (a temporary license is also accepted) before they can apply for a CLP and then a CDL.
Can green card holders or work visa holders apply for a CDL?
Yes, as long as you can submit the proof of legal presence required by federal law. However, applying for a Hazmat (H) endorsement requires being a lawful permanent resident of the U.S. and passing a TSA background check.
How far in advance can I get my medical exam done?
The MER and MEC forms must be signed by a qualified medical examiner within the past 2 years to be accepted. We recommend scheduling your exam 1 to 2 months before you plan to apply, to avoid your certification expiring before your test date.
Can I schedule a test before my documents are complete?
This is not recommended. The DMV requires a complete application before it will administer the knowledge test; if documents are missing, you'll likely be asked to reschedule, wasting your appointment slot and time.
