Getting a CDL involves both federal requirements and state-specific rules that vary in ways that matter for your timeline, costs, and documentation. The federal government sets the baseline — no state can require less — but states set their own fees, testing procedures, and processing timelines. This guide covers CDL requirements by state for 2026: the federal framework, where states commonly differ, how CDL transfers work when you move, and what international drivers need to know.
The Federal Baseline: What Every State Must Follow
CDL standards are federally established under 49 CFR Part 383. States that fail to maintain federal minimum standards risk losing federal highway funding — so compliance is effectively mandatory.
Federal minimums every state must meet:
- Minimum age of 18 for intrastate CDL; 21 for interstate commercial driving
- Valid Commercial Learner’s Permit issued only after passing required knowledge tests
- Minimum 14-day CLP holding period before skills test
- CDL skills test covering pre-trip inspection, basic vehicle control, and on-road driving
- Medical certification requirement — valid DOT medical certificate required
- ELDT compliance — training from a TPR-registered provider required for new Class A/B applicants (since February 7, 2022)
- CDL disqualification rules enforced uniformly (49 CFR 383.51)
- One CDL per driver — only one state can issue your CDL at a time
- Prohibition on masking CDL violations through diversion programs
These are the floor. States cannot go below them.
Where States Commonly Differ
Within the federal framework, state variation affects several practical aspects of getting and maintaining your CDL.
Fees
CDL fees vary significantly by state. This is the area of greatest variation:
| Fee Category | Typical Range Across States |
|---|---|
| CDL knowledge test (per section) | $5 – $60 |
| CDL skills test | $50 – $200 |
| CLP issuance | $10 – $75 |
| CDL issuance | $50 – $150 |
| CDL renewal | $30 – $100 |
Some states charge per test section; others charge a flat fee for all knowledge tests. Verify your state DMV’s current fee schedule — fees change and published lists online are frequently outdated.
Medical Certificate Submission
CDL holders must provide their medical certificate to their state DMV. The timing requirement is federally required, but states handle the submission process differently:
- Self-certification at renewal: Most states require CDL holders to certify their commerce type (interstate or intrastate) at CDL renewal and submit the medical certificate at that time
- Continuous filing: Some states require the medical certificate to be on file with the DMV at all times and must be updated each time it’s renewed
Failure to keep the medical certificate on file with the state can result in CDL downgrade to Class D (non-commercial) regardless of whether the certificate itself is valid.
CDL Renewal Period
CDL renewal periods vary by state:
- 4-year renewal: Some states
- 5-year renewal: Most common
- 8-year renewal: A few states
Your CDL expiration date is set by your state. Renewing typically requires a vision test and knowledge test in some states; others issue renewal without retesting if your record is clean.
Skills Test Appointment Availability
This is a practical difference that affects your timeline more than regulations. Urban DMV locations in states with high CDL demand (California, Texas, Florida, New York) frequently have skills test appointment backlogs of 3–6 weeks or more. Rural DMVs in lower-demand states often schedule within a week.
If your timeline is urgent, look for third-party CDL testing sites authorized by your state — many CDL schools and carriers are authorized to conduct skills tests, and their scheduling is often faster than DMV facilities.
CDL Transfer When You Move to a New State
When you relocate, you must transfer your CDL to your new state of domicile. Federal law prohibits holding CDLs from two states simultaneously — you must surrender your existing CDL when your new state issues one.
General transfer process:
- Establish domicile in your new state (generally 60 days from establishing residence, though states vary)
- Apply for a CDL in your new state, providing your existing out-of-state CDL
- Your new state verifies your record with your previous state through the CDLIS (Commercial Driver’s License Information System)
- Surrender your old CDL at issuance of the new one
Most states do not require retesting for transfers of the same CDL class as long as your license is current and your record meets their standards. A small number of states require a knowledge test or vision test at transfer regardless.
Timing: Most states give you 30–60 days after establishing domicile to transfer your CDL. Check your new state’s deadline — operating on an out-of-state CDL after you’ve established legal domicile in a new state creates a compliance issue.
Special situations:
- If your CDL expired before you initiate transfer, you’ll likely need to renew (and possibly retest) rather than simply transfer
- If you have violations pending in your old state, the CDLIS check will flag them and your new state may impose hold periods
International Drivers: Getting a U.S. CDL
Drivers with foreign commercial licenses cannot simply exchange them for a U.S. CDL. The process requires going through standard U.S. CDL requirements:
What foreign license holders must do:
- Pass CDL knowledge tests at their state DMV
- Complete ELDT training from a TPR-registered provider
- Pass the CDL skills test
- Meet medical and background requirements
Canada exception: Drivers holding Canadian commercial licenses may have specific reciprocity provisions depending on their province and the U.S. state. Some states recognize Canadian commercial licenses for limited purposes. Check your specific state’s reciprocity agreements.
Mexico exception: Mexico and the U.S. have a commercial driver license reciprocity agreement covering certain operations. However, Mexican commercial licenses are not simply converted to U.S. CDLs for interstate commerce — requirements depend on the type of operation.
For specific foreign license reciprocity, contact your state DMV directly. FMCSA maintains general guidance at fmcsa.dot.gov/.
State-Specific Areas to Always Verify Directly
Rather than a state-by-state fee table (which would be outdated quickly given how often fees change), here are the specific items to verify with your state DMV:
- Current CDL knowledge test fee per section
- Current skills test fee
- Whether a vision or road test is required at renewal
- Medical certificate submission process and timing
- Third-party testing site availability in your area
- Specific identification and documentation requirements at your DMV
- Whether your state accepts online CLP applications or requires in-person
The most reliable source is always your state’s official DMV website. Search “[your state] CDL requirements” and navigate to the official DMV or motor vehicles site. Avoid third-party aggregator sites for fees — they are rarely current.
Self-Certification: Commerce Type Declaration
When you get or renew a CDL, you must self-certify your commerce type. The options:
Non-excepted interstate (NI): You operate in interstate commerce and are subject to federal DOT medical standards. Must provide a current DOT medical certificate to your state DMV.
Excepted interstate (EI): You operate in interstate commerce but are exempt from federal medical standards (for example, farm vehicle operators under specific exemptions). Usually does not require a DOT medical certificate.
Non-excepted intrastate (NA): You operate only within your state and are subject to your state’s medical standards, which may differ from federal standards.
Excepted intrastate (EA): You operate only within your state under a state exemption.
Most CDL holders who drive commercially in interstate commerce are NI. This is the category that requires a current DOT medical certificate on file with your state DMV. Getting this wrong — certifying intrastate when you’re actually driving interstate — creates compliance issues for both driver and carrier.
Pros and Cons of Getting Your CDL in a Specific State
Some drivers consider getting their CDL in a specific state if they have flexibility. Practical considerations:
| Factor | Consideration |
|---|---|
| Fees | Some states charge significantly less than others for testing and issuance |
| Scheduling | Some states have shorter wait times for skills test appointments |
| Requirements | Some states have slightly different documentation requirements |
| Reciprocity | All states honor CDLs from other states — your license works nationwide |
| Domicile requirement | You must get your CDL in your state of legal domicile — you can’t “shop” states |
The domicile requirement is a real constraint. You get your CDL in the state where you actually live, not the state with the most favorable fees or easiest process.
Frequently Asked Questions
Usually not, if your CDL is current and you’re transferring the same class of license. Most states process transfers based on your existing CDL and your record verified through CDLIS without requiring you to retest. A small number of states require a vision test or knowledge test at transfer. Check your new state’s specific rules.
No. Federal law prohibits holding commercial driver’s licenses from more than one state. When your new state issues your CDL, you surrender your old one. CDLIS tracks CDL history and flags attempts to hold multiple licenses.
Most states require CDL transfer within 30–60 days of establishing domicile. The specific deadline varies by state. Operating on an out-of-state CDL after becoming a legal resident of a new state creates a compliance issue — transfer promptly.
No. CDL fees vary significantly by state — from around $50 total to over $200 depending on the state’s fee schedule. Verify your state DMV’s current fees directly, as they change periodically.
Yes. A CDL issued by any U.S. state is valid for commercial driving in all other states, as long as the license is current and you have the correct class and endorsements for the vehicle you’re operating.
