Illinois CDL Commercial Study Guide: CDL Driver License Manual: August 2025 Update (Illinois Drivers Handbook (Workbook, handbook, GDL Parent-Teen Driving Guide, CDL Guide))

Preface:

The commercial motor vehicle industry plays a crucial role in Illinois’ transportation system and in the movement of goods across the state and the country. Truck drivers are essential to that system and to the growth of the state’s economy. This Commercial Driver’s License guide provides information for drivers applying for or holding a Commercial Learner’s Permit or Commercial Driver’s License in Illinois. It covers safe driving practices, cargo and passenger transportation, air brakes, combination vehicles, hazardous materials, school bus and charter bus operation, vehicle inspection, control skills, on-road testing, and special CDL/CLP requirements. Federal law requires CDL and CLP applicants and holders to certify their commercial driving medical status, and certain drivers must keep a current DOT medical certificate on file with the Secretary of State’s office. The guide also explains programs for qualified current or former military personnel, including exemptions connected to military heavy-vehicle experience.
