Am I eligible for a CDL in Colorado?
You can get a Colorado CDL at 18 to drive commercially inside Colorado, or at 21 to drive across state lines, haul hazmat, or transport placarded loads. You need a Colorado residential address, a valid Colorado driver's license in good standing, and — for most classes — a current DOT medical certificate.
Disqualifiers are federal, not state: a suspended license, certain drug or alcohol convictions, or an open Drug & Alcohol Clearinghouse prohibition will stop you at the counter. Clear those first — the rest of this page assumes you're eligible.
As of September 29, 2025 the Colorado DMV paused issuance and renewals of term-limited (non-domiciled) CDLs and CLPs until further notice
New to the requirement? What is ELDT? →
Step 1 · How do I complete ELDT theory training?
Since February 7, 2022, the FMCSA requires Entry-Level Driver Training before you can take the CDL knowledge test. Take the theory course from a provider on the federal Training Provider Registry, and your completion is reported electronically to the registry — usually within a day.
This step is not Colorado-specific. The theory curriculum is standardized nationally under 49 CFR Part 380, so a $150 course and a $20 course put the identical record in the same federal registry. Paying more buys marketing, not a better certificate.

Self-paced · finishable in one day · lifetime access · no subscription
Need endorsements too? The All-Access bundle covers all 7 courses for $49.
Step 2 · How do I get a Colorado CDL learner's permit?
Once your ELDT completion is in the federal registry, take your documents to a Colorado Division of Motor Vehicles (DMV) driver exam station and pass the general knowledge test plus any endorsement tests. The agency issues your commercial learner's permit (CLP), and you must hold it at least 14 days before the skills test.
- Permit fee: $19.00 ("Instruction Permit" line item under the Commercial Driver's License Fees table)
- Permit validity: 1 year; not eligible for renewal (rule effective April 18, 2024)
Bring with you — per the CO checklist
- Valid driver license or commercial learner's permit
- Current DOT medical card from an FMCSA-certified medical examiner
- Proof of identity and lawful presence
- Social Security number
- Two proofs of Colorado residency dated within the last year
- Entry-Level Driver Training (ELDT) completion for entry-level applicants
Knowledge test covers
- Class A - General Knowledge
- Combination
- Air Brakes (if applicable)
- Class B - General Knowledge
- Air Brakes (if applicable)
- Class C - General Knowledge
Step 3 · Do I need behind-the-wheel training?
Yes. ELDT has two halves: the theory course you finished in step 1, and behind-the-wheel (BTW) training on a range and on public roads. BTW must be done in person with a registered provider, has no minimum hour requirement, and ends when an instructor judges you proficient.
Your CLP lets you drive a commercial vehicle only with a qualified CDL holder in the passenger seat. Most drivers do BTW through a local school or a carrier-sponsored program — look near Denver, Colorado Springs, or Aurora.
Step 4 · How do I schedule the Colorado skills test?
Colorado runs CDL skills testing through examiners approved by the Colorado Division of Motor Vehicles (DMV), and you schedule once your 14-day CLP hold is up. The test has three parts — pre-trip inspection, basic control skills, and an on-road drive — and you must supply a vehicle representing the class you're testing for.
- Skills test fee: Not published by the state - drive skills tests are given by state-approved third-party CDL testing units that set their own fees
- Third-party testing: yes - drive skills tests are scheduled with approved third-party CDL testing units certified under C.R.S. 42-2-407 (list published by DMV); DMV offices handle…
Driving Knowledge (Written) Retest fee $11.50 (Other Fees table). Knowledge test results are valid for only one CLP issuance; changing class or endorsement requires retaking all exams. No wait period published.
Step 5 · Do I need a DOT medical card?
Almost certainly. Most CDL drivers must pass a DOT physical with an examiner listed on the FMCSA National Registry and file the certificate with the state. A standard card is good for up to 24 months; conditions like high blood pressure or diabetes can shorten that to 12 months or less.
Get this done before your Colorado Division of Motor Vehicles (DMV) visit — you'll need the certificate on file to be issued the CLP, so it isn't really step 5 in practice.
Step 6 · When do I actually get the CDL?
After you pass the skills test, you take the examiner's results and your CLP to the Colorado Division of Motor Vehicles (DMV), pay the license fee, and are issued a temporary CDL on the spot. The permanent card arrives by mail, and your driving record shows the class and endorsements immediately.
Endorsements you skipped now can be added later — each one is a knowledge test, and Hazmat adds a TSA background check.
- License fee: $17.50 (fee table lists no term; CDL general information page states CDLs are valid 4 years)
- License term: 4 years
- Credentials are mailed from a secure central location and "usually arrive in 8-10 days, but may take up to 30 days to be delivered"

Colorado CDL questions
No. Transferring an existing, valid CDL to Colorado is a license transfer at the Colorado Division of Motor Vehicles (DMV), not new training. ELDT is required only when you first obtain a Class A or B CDL, upgrade a class, or add a Hazmat, Passenger, or School Bus endorsement for the first time.
Most people take four to eight weeks. Theory training is one day, the CLP hold is 14 days minimum, and the rest is behind-the-wheel practice and how far out your skills test appointment lands. Metro testing sites book further out than rural ones.
It is if the provider is listed on the FMCSA Training Provider Registry — that listing is the only thing that makes any theory course count. The curriculum is standardized in 49 CFR Part 380, so every registered provider teaches the same required topics.
Yes, for intrastate driving only. You must be 21 to drive across state lines, haul hazardous materials requiring placards, or transport passengers interstate.
No. Our course is the theory half. Behind-the-wheel must be completed in person with a registered provider on a range and on public roads, and it is priced and scheduled separately.
No. ELDT is training, not an exam. You still take Colorado's knowledge test for the CLP and the three-part skills test for the CDL, both administered by the state.
You retake only the portion you failed, but each attempt carries its own fee and requires a new appointment. Your CLP must still be valid on the retest date.
