Topics Covered

General Knowledge

The starting point for every CDL, covering safe driving, cargo handling, vehicle systems, and emergency procedures that all commercial drivers are tested on. It is the prerequisite for every class-specific and endorsement knowledge exam.

Air Brakes

Nearly all Class A and many Class B vehicles require air brake knowledge to avoid a license restriction. This section covers the full air brake system from components through failure modes as tested on the written exam.

Combination Vehicles

Class A authority requires passing the Combination Vehicles written test, covering tractor-trailer coupling, air line connections, and multi-unit handling. It is the primary Class A-specific test topic.

All 7 Endorsements

The Complete CDL Study Package covers all seven CDL endorsements: HazMat, Tank, Passenger, School Bus, Doubles and Triples, Air Brakes, and Combination Vehicles. Each endorsement has its own separate written test that must be passed to add that authority to your license.

Skills Test Readiness

The CDL skills test has three graded sections: pre-trip inspection, basic control exercises, and on-road driving. This section prepares you for scoring criteria, common failure points, and what to expect on test day.
