CDL Requirements in Illinois (2026): Steps, Cost & Testing

Source review dated July 20, 2026 against Illinois Secretary of State — Driver Services Department (Commercial Driver's License Section)

Illinois issues CDLs through the Secretary of State's Driver Services Department — not a DMV. You keep your regular Illinois license as a base, get a Commercial Learner's Permit (about $50), hold it 14 days while you finish ELDT, then pass a three-part skills test in a truck you supply at a Secretary of State CDL testing facility. The classified CDL is about $60 and is valid 4 years.

This guide combines federal rules with dated state research. Read the review notes before paying fees or booking a test.

State fees are modest — roughly $50 for the CLP and $60 for the 4-year classified CDL — and Illinois doesn't charge a separate per-skills-test fee. The larger costs are ELDT tuition (estimated at roughly $3,000–$8,000 for a private Class A program) and, for hazmat, the TSA/IdentoGO fingerprint and threat-assessment fee. Because ilsos.gov's fee page could not be fetched directly, confirm exact current amounts with the Secretary of State before relying on them.

Two features stand out. First, Illinois is not one of the eight TSA self-managed hazmat states, so hazmat applicants use the standard TSA Universal Enrollment process through IdentoGO rather than an in-office program. Second, Illinois joined FMCSA's medical-certificate National Registry integration in 2025, so medical examiners now transmit your exam results electronically and the state no longer accepts paper cards at CDL facilities. Veterans with qualifying military driving experience can also waive part or all of their CDL testing through the state's Military CDL Waiver.

Eligibility and documents in Illinois

• Age: at least 18 for intrastate driving; 21 to drive interstate or haul hazmat.
• One document from each of the Secretary of State's acceptable-ID groups A, B, C, and D (identity, written signature, date of birth, and residency/Social Security)
• Proof of legal presence and Illinois domicile (required at initial issuance, renewal, transfer, or upgrade)
• Social Security number (verified electronically)
• A valid Illinois base driver's license (non-CDL or CDL) to hold a CLP
• Medical self-certification of your operating category; a valid medical examiner's certificate on file (transmitted electronically by your examiner) if your category requires one
• ELDT completion recorded to your Illinois driving record (for first-time Class A/B and first-time P/S/H)

How to get your CDL: step by step

1. 1

   Check eligibility, documents, and medical qualification

   Choose the CDL class and endorsements for your vehicle. Hold the required regular license and bring Illinois identity, residency, and Social Security documents. Self-certify your operating category and complete a DOT physical before the permit if that category requires medical certification.

2. 2

   Pass the knowledge tests and obtain your CLP

   Take general knowledge and the vehicle/endorsement tests that apply. ELDT theory may be taken earlier, but federal rules do not require it before the CLP. A first-time hazmat applicant must complete hazmat theory before the hazmat knowledge test; hazmat is not issued on a CLP.

3. 3

   Complete required training and practice during the permit hold

   Hold the CLP for at least 14 days before the skills test. Use a qualified supervising driver for public-road practice. First-time Class A/B, B-to-A upgrades, and first-time P/S endorsements require applicable theory and behind-the-wheel ELDT from registered providers. The appropriate CLP is needed for public-road training. State training requirements may add to the federal baseline.

4. 4

   Pass the skills test in the right vehicle

   Confirm ELDT completion is recorded, arrange the test and a representative vehicle, then complete vehicle inspection, basic control, and road driving. The vehicle and transmission you test in can restrict your license.

5. 5

   Complete issuance and maintain your qualifications

   Pay the applicable Illinois issuance fees and confirm the correct class, endorsements, restrictions, and expiration. Keep your medical status current when required and follow the agency’s renewal instructions.

Medical certification in Illinois

Self-certify your operating category at a Secretary of State CDL facility. Illinois joined FMCSA's National Registry integration in 2025: your certified medical examiner now enters your exam results directly into the FMCSA National Registry, and the Secretary of State collects that data electronically and updates your record — the office no longer accepts paper medical certificates at CDL facilities. New CLP/CDL applicants may need to self-certify under a category other than Non-excepted Interstate until their Illinois CDL record is established, then update it at any CDL facility.

If your card lapses: If your medical examiner's certificate expires, or your examiner fails to submit the results, your CDL can be downgraded. If any information is missing or incorrect you must contact the examiner to re-enter or correct it. For an H or X endorsement, begin renewal about 60 days before your CDL expires.

Every CDL holder must self-certify one operating category. The categories offered here:

• NI — Non-excepted Interstate (medical card required)
• EI — Excepted Interstate (no card)
• NA — Non-excepted Intrastate (card required)
• EA — Excepted Intrastate

What a CDL costs in Illinois

These are separate transaction types, not charges that every applicant pays. Renewal, replacement, endorsement, and retest fees are alternatives or extras. Amounts are from the dated research; check current official fees before paying.

Illinois does not publish a separate per-skills-test fee — testing is part of the CLP/CDL process. The biggest out-of-pocket costs are ELDT tuition and, for hazmat, the TSA/IdentoGO fingerprint and threat-assessment fee (set by TSA, not the Secretary of State — confirm with IdentoGO/TSA). A hazmat/X endorsement must be renewed with a fresh threat assessment and knowledge test each cycle.

See the full national breakdown on our CDL cost guide.

Skills testing in Illinois

Testing access: State / approved third parties. Official testing instructions.

Illinois allows approved third-party testers to administer the CDL skills test, with availability and fees set by the provider. Availability varies by facility; the Fast Pass system lets you book in advance, but you cannot select a test date inside the 14-day CLP hold. Popular Chicago-area facilities can book out further, which is part of why many drivers use employer or school third-party testers. Specific wait times are not published — check Fast Pass for live availability.

Your test vehicle: You must bring a representative vehicle of the proper class, with the proper equipment, for the CDL you want. The Secretary of State does not provide a test vehicle.

Endorsements available in Illinois

Illinois offers the standard federal endorsements. Adding one usually means an extra knowledge test (and a skills test for passenger and school bus). Tap an endorsement for the full federal process and cost:

• HHazmat — Hazardous materials. Illinois is NOT a TSA self-managed state, so you use the standard TSA HazMat Threat Assessment Program through the Universal Enrollment provider (IdentoGO/IDEMIA): pre-enroll with TSA, get fingerprinted at an IdentoGO center, and pass the security threat assessment before you can take the hazmat knowledge test. ELDT is required for first-timers. Issuance is prohibited until TSA approves.
• NTanker — Tank vehicles. No TSA background check; available with the tank knowledge test.
• XHazmat + Tank — Combined tank + hazmat. Requires the TSA security threat assessment (same as H) plus the tank and hazmat knowledge tests.
• PPassenger — Passenger. Requires ELDT for first-timers plus a passenger knowledge and skills test; adding it to an existing CDL needs a fresh CLP and 14-day hold.
• SSchool Bus — School bus. Requires ELDT for first-timers, the passenger and school-bus knowledge tests, and a school-bus skills test. Cannot be obtained through the military skills-test waiver.
• TDoubles/Triples — Double/triple trailers. Knowledge test only; no skills test or TSA check.

CDL disqualifications

Disqualifying offenses are set by federal law (49 CFR 383.51) and apply in every state. Some also apply in a personal vehicle; vehicle-specific conditions matter. Illinois applies the federal 49 CFR 383.51 disqualification framework (major offenses, serious traffic violations, railroad-crossing and out-of-service violations), implemented through the Illinois Vehicle Code (625 ILCS 5) and Secretary of State rules at 92 Ill. Admin. Code 1030. Confirm any Illinois-specific disqualification or reinstatement details with the Secretary of State.

The offenses that trigger a disqualification, the length of each, and the federal exceptions are listed once in our CDL disqualifications guide instead of repeating the table here. Check the review notes for any Illinois-specific additions we could not confirm.

Military skills-test waiver

Check the temporary July 30–October 29, 2026 federal eligibility extension and ask the state whether it participates.

Illinois offers a Military CDL Waiver with two options: the Even Exchange (waives both knowledge and skills testing for members with qualifying MOS/ratings) and the Skills Test Waiver (waives skills testing but not the knowledge tests). It is for active members or those discharged within the past 12 months, applies to an initial CDL only (not upgrades or restriction changes), and does not cover endorsements that require a skills test. Applications are submitted by the applicant and commanding officer to the CDL Division ([email protected]).
