Illinois CDL Industry Overview

Illinois is the nation's major rail and trucking crossroads. Chicago is the largest rail hub in North America, and the Chicago metro area handles a disproportionate share of the country's freight. Major interstates including I-80, I-90, I-94, and I-55 make Illinois a critical corridor for cross-country trucking.

The agriculture industry in downstate Illinois (corn, soybeans, grain) creates seasonal demand for CDL drivers, particularly grain haulers with tanker or combination vehicle endorsements.
