Getting your CDL license in 2026 is a clear, step-by-step process — but there are more moving parts than most people expect going in. Between the medical requirements, the ELDT training rules, the written tests, and the skills test, first-time applicants often spend months preparing before they hold a license in their hands. This guide walks you through every stage so you know exactly what’s coming.

Step 1: Make Sure You Meet the Basic Eligibility Requirements
Before you spend money on training or testing, confirm you actually qualify. The federal minimums under 49 CFR Part 383 set the floor — your state may add requirements on top of these.
| Requirement | Federal Minimum | Notes |
|---|---|---|
| Minimum age — interstate | 21 years old | Crossing state lines or hauling hazmat |
| Minimum age — intrastate | 18 years old | Within one state only; varies by state |
| Current driver’s license | Required | Must surrender when CDL is issued |
| Social Security Number | Required | For CDLIS verification |
| DOT medical certificate | Required | From FMCSA-registered examiner |
| Clean driving record | State-specific | DUIs and certain felonies are disqualifying |
One thing that surprises people: you can only hold a CDL in one state. If you have a license in multiple states, that needs to be sorted out before you can get a CDL. The Commercial Driver’s License Information System (CDLIS) tracks every CDL holder nationally — the DMV will check it when you apply.
Step 2: Choose the Right CDL Class
CDLs come in three classes, and choosing the right one determines what vehicles you can legally operate. Pick the wrong one and you’ll need to upgrade later.
Class A CDL
This is the big one — and what most people mean when they say “get your CDL.” A Class A authorizes you to operate any combination vehicle with a gross combination weight rating (GCWR) of 26,001 pounds or more, where the towed unit weighs more than 10,000 pounds. Think tractor-trailers, flatbeds, tankers. Class A holders can also drive Class B and C vehicles.
Class B CDL
Class B covers single vehicles over 26,000 pounds GVWR — straight trucks, large buses, dump trucks, delivery vehicles. You can tow something with a Class B, but only if the trailer weighs 10,000 pounds or less. Class B holders can also drive Class C vehicles.
Class C CDL
Class C is for vehicles that don’t fall into A or B but still require a CDL — specifically vehicles designed for 16 or more passengers (including the driver), or vehicles hauling hazardous materials requiring placarding. Think smaller shuttle buses, certain HazMat delivery vehicles.
For most people pursuing trucking careers, a Class A is the target — it opens the most job opportunities and provides the most flexibility. Our truck driving salary guide breaks down how CDL class affects your earning potential.
Step 3: Pass the DOT Physical and Get Your Medical Card
You cannot get a CDL without a valid DOT medical examiner’s certificate. The exam must be performed by a provider listed on the FMCSA National Registry of Certified Medical Examiners. Do this before you start spending money on training — if you have a medical condition that could disqualify you, you want to know about it now, not after paying for CDL school.
The exam covers vision, hearing, blood pressure, urinalysis, and a full physical. Common disqualifying conditions include untreated sleep apnea, Stage 3 hypertension, insulin-dependent diabetes (without an FMCSA exemption), and active substance use disorders. For a detailed breakdown of what’s tested and how to prepare, see our full DOT physical exam guide.
Step 4: Get Your Commercial Learner’s Permit (CLP)
The CLP is your legal right to practice driving a CMV on public roads — with a qualified CDL holder in the passenger seat. You can’t take the CDL skills test without one, and you must hold it for a minimum of 14 days before you’re eligible to test.
To get your CLP at the DMV, you’ll need to:
- Present your current driver’s license and proof of residency
- Provide your Social Security number
- Show your valid DOT medical examiner’s certificate
- Pass the General Knowledge written test (required for all CDL classes)
- Pass additional knowledge tests for your intended endorsements or restrictions (Air Brakes, Combination Vehicles if applicable)
- Pay the CLP fee (varies by state — typically $20–$50)
Study for the General Knowledge test using your state’s CDL driver’s manual. It’s based on the federal model curriculum, so content is consistent across states. Our CDL written test study guide covers all major topic areas in detail.
Step 5: Complete Entry-Level Driver Training (ELDT)
Since February 7, 2022, all first-time CDL applicants must complete Entry-Level Driver Training from a provider listed on FMCSA’s Training Provider Registry (TPR). This is a federal requirement you cannot skip.
ELDT has two components:
- Theory training — Covers the knowledge areas required for your CDL class. Can be done online or in a classroom. No FMCSA-mandated minimum hours, but the curriculum must cover all required topics.
- Behind-the-wheel (BTW) training — Hands-on driving instruction in an actual CMV, covering all required skill areas. Must be conducted by an approved BTW instructor at a TPR-registered location.
When you complete ELDT, your training provider submits your completion record electronically to FMCSA’s TPR system. Your state DMV verifies this before scheduling your skills test. You don’t get a paper certificate — the electronic record is the official confirmation. If your provider delays uploading it, contact them immediately — your skills test can’t be scheduled until it’s in the system.
For complete details on ELDT curriculum requirements, exemptions, and how to find a quality program, see our ELDT requirements guide.
Step 6: Pass the CDL Skills Test
The skills test is the final, most comprehensive hurdle. It has three components, all of which must be passed:
Pre-Trip Vehicle Inspection
You’ll systematically inspect the vehicle and verbally describe what you’re checking and what you’re looking for. Examiners grade whether you check required items and follow correct procedure — not whether you actually find a defect. Learn the 7-step sequence cold and practice it daily during your training. Our CDL pre-trip inspection guide covers every item in the sequence.
Basic Vehicle Control
This section tests your ability to maneuver the vehicle in a controlled area — think cones and markers. Common exercises include straight-line backing, offset backing, parallel parking (driver-side and blind-side), and stop exercises. Touching a cone is typically an automatic failure on that exercise.
On-Road Driving
The examiner rides with you through a predetermined route covering city streets, highway driving, and various traffic scenarios. They score your turns, lane changes, intersection behavior, following distance, speed management, and railroad crossing procedure.
For detailed scoring criteria and preparation tips for all three sections, see our CDL road test guide.
Step 7: Get Your CDL Issued
After passing the skills test, your state DMV issues your CDL — typically a physical card within 7–14 days with a temporary paper document in the meantime. Your license will show your class (A, B, or C) and any endorsements or restrictions earned. The L restriction (no air brakes) is placed on your CDL if your skills test vehicle didn’t have air brakes — you can remove it later by passing the Air Brakes knowledge test.
Your CDL is valid for the period set by your state — typically 4 to 8 years. But your DOT medical certificate has its own expiration that’s separate from your CDL and must be maintained continuously. Let it expire and you can’t legally drive a CMV, even with a perfectly valid CDL.
What Does a CDL Cost in 2026?
| Cost Item | Typical Range | Notes |
|---|---|---|
| DOT physical exam | $75 – $175 | Not covered by health insurance |
| CLP application fee | $20 – $50 | State DMV fee varies |
| Knowledge test fees | $0 – $30 per test | Often included in DMV CLP fee |
| ELDT / CDL school | $0 – $10,000 | Free with carrier-sponsored programs; up to $10K for private school |
| CDL issuance fee | $40 – $100 | State DMV fee |
| Skills test fee | $0 – $200 | Often included if tested through your CDL school |
Carrier-sponsored programs offer the lowest upfront cost — often zero — but come with a driving commitment (usually 1 year). Breaking the commitment early typically triggers repayment of training costs. Read any contract carefully before signing.
