The CDL General Knowledge test is the foundation of your commercial driver’s license. Every CDL applicant must pass this section regardless of the class of license or endorsements sought.
This category covers vehicle operation fundamentals for large commercial vehicles: proper documentation (medical certificates, logbooks, shipping papers), vehicle inspection requirements, basic control of large vehicles, and understanding the responsibilities that come with operating commercial motor vehicles on public roads.
You’ll also need to understand hours-of-service regulations, cargo securement basics, and the Federal Motor Carrier Safety Regulations (FMCSRs) that govern all CDL holders. Expect questions on accident reporting procedures and the consequences of violations.
