The 2026 Commercial Driver’s License (CDL) exam consists of two main sections: the written knowledge test and the skills test. While the skills practical exam will evaluate your ability to operate commercial vehicles, the written test covers various topics of commercial driving theory, such as basic control skills, driving at night, driving in poor weather and the basics of a pre-trip inspection procedure.
Commercial drivers must thoroughly check their vehicle before getting behind the wheel. This pre-trip inspection usually involves checking the brakes, steering mechanism, lights, tires, wheels and emergency equipment, among other things. If you think this procedure is more difficult than the preflight checklist of a Boeing 747, you’ll find it easier to perform this inspection once you fully master it.
As a commercial driver, you may be responsible for transporting expensive cargo, hazardous materials or a large number of passengers. It is crucial that your vehicle is in proper working condition and poses no safety risks. This is why a pre-trip inspection is a beneficial requirement that can prevent accidents.
