Illinois CDL & ELDT Requirements — Complete 2026 Guide

Illinois CDL Requirements — The Complete Picture

To get a Commercial Driver's License in Illinois, you work through Illinois Secretary of State — Driver Services (IL SOS). The federal FMCSA ELDT mandate (effective February 7, 2022) applies in every state including Illinois — any new CDL applicant, class upgrade, or endorsement addition requires you to complete FMCSA-approved ELDT before sitting for the CDL skills test.

The complete sequence for a first-time CDL applicant in Illinois:

• Pass the DMV permit test at IL SOS → get your Commercial Learner's Permit (CLP)
• Hold the CLP for at least 14 days (federal minimum, Illinois follows federal)
• Complete FMCSA-approved ELDT theory training (this is what DLA Academy provides — $20 per course)
• Complete behind-the-wheel (BTW) training at a local FMCSA-registered BTW provider — separate from DLA Academy
• Pass the CDL skills test at IL SOS (pre-trip inspection, basic vehicle control, road test)
• Receive your Illinois CDL

Hazmat endorsement applicants additionally need TSA threat-assessment fingerprinting through IDEMIA Universal Enroll (standard process — typical wait time 30–45 days for clearance).

Behind-the-Wheel (BTW) Training — Required, But Not From Us

For CDL-A and CDL-B applicants, federal ELDT requirements have two parts: theory (what DLA Academy provides) and behind-the-wheel training (BTW). BTW must be completed at a local FMCSA-registered BTW provider — typically a trucking school, a CDL training facility, or an employer-sponsored program. DLA Academy does not offer BTW.

BTW for CDL-A and CDL-B typically takes 40–160+ hours depending on the program, costs $3,000–$10,000+ depending on the provider, and must be done at an FMCSA-registered facility (the FMCSA TPR has a directory) — many are located in Illinois metro areas.

For Hazmat, Passenger, and School Bus endorsements: no BTW required. Those endorsements are theory-only on the federal side — though some states require additional in-vehicle testing for School Bus and Passenger at the state level.

Pre-February 2022 CDL Holders — Are You Grandfathered?

The FMCSA ELDT mandate took effect February 7, 2022. If your CDL was issued before that date, you are grandfathered for your current license class. You don't have to retroactively complete ELDT to keep driving.

BUT — grandfathering only covers your existing license class. If you're doing any of the following after February 7, 2022, ELDT is required regardless of when your CDL was issued:

• Upgrading from Class B to Class A → need CDL-A Theory ELDT
• Upgrading from Class C to Class B → need CDL-B Theory ELDT
• Adding the Hazmat (H) endorsement → need Hazmat ELDT
• Adding the Passenger (P) endorsement → need Passenger ELDT
• Adding the School Bus (S) endorsement → need School Bus ELDT

Illinois Secretary of State — Driver Services (IL SOS) verifies your ELDT completion through the FMCSA TPR before issuing the new class or endorsement.
