2026 Illinois CDL changes and what to expect in 2027
Several Illinois CDL rules changed in 2026. The Illinois Secretary of State updated the CDL manual in March 2026 to align with the FMCSA 2026 entry-level driver training (ELDT) requirements, adding new content on the ELDT theory and behind-the-wheel hours, per the FMCSA 2026 ELDT update. The CDL General Knowledge test added 5 new questions on the ELDT theory, bringing the total to 55 questions (50 scored, 5 unscored pretest items).
Illinois CDL fees for 2026 are 60 USD for the Class A license (up from 50 USD), 50 USD for Class B (up from 40 USD), and 40 USD for Class C (up from 30 USD). The retake policy remains a 7-day waiting period between attempts. The CDL skills test (3-part pre-trip, basic vehicle control, on-road driving) is now available at 8 Illinois testing locations, up from 6 in 2025.
For 2026 candidates, the practical impact is that the 5 new ELDT questions are pretest items that don't count toward the score but are used for future test validation, so the actual pass mark remains 80% on 50 scored questions (40 correct answers). For 2027 candidates, the FMCSA is expected to add ELDT refresher hours for existing CDL holders, which would affect renewal rather than initial testing. The CDL skills test fee is set to rise to 75 USD in 2027 per the Secretary of State 2026 fee schedule.
Illinois CDL career outlook 2026
Illinois is a major freight hub — Chicago is the third-largest freight market in the US, anchored by rail intermodal yards (BNSF, UP, CSX), O Hare cargo, and Midwest distribution centres (Amazon, Walmart, FedEx). The Bureau of Labor Statistics (BLS, 2026) reports heavy-truck driver median wage of $56,400 in Illinois — above the national median of $50,200 — with top-10% earners exceeding $79,000. Local-route drivers in Chicago suburbs can earn $70,000+ with regular schedules; OTR drivers typically earn $60,000-$75,000 in year one. Illinois-specific endorsements add $1-$4 per hour. Apprenticeship programs at Illinois carriers (UPS Freight, YRC, Saia, Old Dominion) offer paid CDL training — most require 12-24 month commitments. Winter weather (lake-effect snow in Chicago, northern IL) demands additional HOS awareness and ELD discipline. IL SOS Driver Services facilities offering CDL skills tests are concentrated in Chicago, Springfield, Rockford, Peoria, and East St. Louis.
