Am I eligible for a CDL in Illinois?
You can get an Illinois CDL at 18 to drive commercially inside Illinois, or at 21 to drive across state lines, haul hazmat, or transport placarded loads. You need an Illinois residential address, a valid Illinois 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.
No original or upgraded CDL requiring a skills test may be issued unless the applicant has held a CLP for the applicable class/endorsement for a minimum of 14 calendar days (625 ILCS 5/6-508). First-time applicants must complete Entry-Level Driver Training through an FMCSA-listed provider, with theory and behind-the-wheel portions completed within one year. Skills-test waivers are available for qualifying military CMV drivers. Under the covered farm vehicle provisions of 625 ILCS 5/6-507, 21 is the threshold for interstate operation and 18 for intrastate.

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 Illinois-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.

Step 2 · How do I get an Illinois CDL learner's permit?
Once your ELDT completion is in the federal registry, take your documents to an Illinois Secretary of State 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: $50.00 statutory fee for a valid Illinois driver's license holder changing to a commercial learner's permit/CDL classification ($6 CDLIS/AAMVAnet/NMVTIS Trust Fund + $20 Motor Carrier Safety Inspection Fund + $24 CDL classification); $5.00 if a current CDL holder changes classification, endorsement or restriction (625 ILCS 5/6-118)
Bring with you
- Proof of identity & SSN
- Two proofs of Illinois residency
- Current DOT medical certificate
- Your Illinois driver's license
Knowledge test covers
- General knowledge (all applicants)
- Air brakes (if not restricted)
- Combination vehicles (Class A)
- Endorsement tests you're adding
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 Chicago, Aurora, or Springfield.
Step 4 · How do I schedule the Illinois skills test?
Illinois runs CDL skills testing through examiners approved by the Illinois Secretary of State, 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 established as a separate fee by statute - 625 ILCS 5/6-118 sets only credential fees ($50 commercial learner's permit classification change, $60 original or renewal CDL, $5 CDL duplicate) and contains no CDL skills-test, road-test, examination or retest fee; skills tests may also be given by third-party testers authorized under 625 ILCS 5/6-508, whose charges the state does not publish
- Third-party testing: yes - 625 ILCS 5/6-508 authorizes the Secretary of State to permit third party testers, in accordance with 49 CFR 383.75 and 384.228-384.229, to administer the…
Fail one part and you retest only that part, but each attempt is charged separately and slots fill weeks out in metro areas. Book the date before you finish BTW.
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 Illinois Secretary of State 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 Illinois Secretary of State, 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: $60.00 original or renewal CDL ($6 CDLIS/AAMVAnet/NMVTIS Trust Fund + $20 Motor Carrier Safety Inspection Fund + $10 driver's license + $24 CDL); the $24 CDL portion may be prorated to the expiration date of the applicant's Illinois driver's license. Duplicate or corrected CDL $5.00. (625 ILCS 5/6-118)
- License term: 4 years

Illinois CDL questions
No. Transferring an existing, valid CDL to Illinois is a license transfer at the Illinois Secretary of State, 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 Illinois'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.
