Core Knowledge Areas Covered in the Practice Test
To operate a Class A commercial vehicle safely, drivers must master several core domains tested during the written CDL exam. Our practice modules cover the following essential topics:
1. General Knowledge
The General Knowledge test is required for all CDL applicants. Questions assess your understanding of basic vehicle control, visual search techniques, space management, speed control, hazard perception, night driving, mountain driving, emergency maneuvers, and official DOT safety regulations.
2. Combination Vehicles
Class A vehicles primary consist of combination rigs (tractor-trailers, doubles, or triples). This section evaluates your understanding of rollover risks, anti-lock braking systems (ABS), coupling and uncoupling procedures, trailer inspections, and driving safely with long/heavy combinations.
3. Air Brakes
Most Class A vehicles use air brakes. You will be tested on dual air brake systems, main component parts (compressor, governor, reservoirs, valves), air brake safety inspections, low-pressure warning signals, and proper emergency braking techniques.
