This commercial driver study guide covers relevant Federal Motor Carrier Safety Administration (FMCSA) Entry-Level Driver Training (ELDT) concepts and Illinois commercial driver knowledge topics. Review the regulations, procedures, and safety checklists below as part of your CDL and commercial learner permit (CLP) preparation.
CDL trigger
A CDL is required for a 26,001-pound combination when the towed unit exceeds 10,000 pounds.
Classes
Class B covers a single vehicle rated 26,001 pounds or more, including one towing 10,000 pounds or less.
Passenger and HazMat
A vehicle designed for 16 or more people including the driver, or one requiring HazMat placards, requires a CDL regardless of size.
Exemptions
An exemption removes the CDL requirement only when every stated use and operating condition is satisfied.
Exam focus
Apply the rule to the vehicle, credential, trip, or testing situation described. Do not substitute another state’s procedure for the Illinois rule.
Commercial Driver License Exam Readiness: Achieving a passing grade of 80% or higher on state DMV commercial driver knowledge exams requires mastery of federal vehicle inspection procedures, gross vehicle weight ratings (GVWR / GCWR), braking mechanics, and road safety regulations.
