CDL inspection and maintenance study guide

Part 396 of the Federal Motor Carrier Safety Regulations (49 CFR Part 396) covers inspection, repair, and maintenance of commercial motor vehicles. This guide sets out what the rule text states on the motor carrier's general maintenance duty, maintenance records and how long they are kept, roadside inspections and out-of-service vehicles, driver vehicle inspection reports and the driver's review before driving, the periodic (annual) inspection, inspector qualifications and inspection reports, and brake inspector qualifications. Many of these duties fall on the motor carrier rather than the driver, and the guide says who each one applies to. Rules that apply only to intermodal equipment providers are mostly left out. This is study material, not the State knowledge test. Every point links to the regulation and quotes its exact words.
