This commercial driver study guide covers relevant Federal Motor Carrier Safety Administration (FMCSA) Entry-Level Driver Training (ELDT) concepts and Virginia commercial driver knowledge topics. Review the regulations, procedures, and safety checklists below as part of your CDL and commercial learner permit (CLP) preparation.
Passenger CDL trigger
A vehicle designed for 16 or more occupants including the driver requires the appropriate passenger CDL authority even if it is below Class A or B weight. The applicant passes passenger knowledge and tests in the passenger group intended for operation.
School bus of 16 or more
A school bus designed for 16 or more occupants requires a CDL of the correct class plus passenger and school-bus endorsements. The applicant completes General Knowledge, P, S, and Air Brakes when equipped, followed by a representative skills test.
Virginia small-school-bus path
For a school bus designed for fewer than 16 occupants including the driver, Virginia does not require a CDL or P endorsement, but it does require the school-bus endorsement on the driver's license and the school-bus knowledge and skills tests. The license is restricted to the smaller bus.
Registry restrictions
A person required to register with Virginia's Sex Offender and Crimes Against Minors Registry cannot hold S during the registration period. P authority must carry Q when required, prohibiting transportation of children for school or licensed daycare activities.
School-bus operating rules
Virginia requires school-bus drivers to wear safety belts and prohibits handheld and hands-free phone use while operating a school bus except an emergency or lawful parked dispatch purpose. Authorized hands-free two-way communication with school or public-safety officials is treated separately.
Exam focus
Apply each rule to the exact Virginia credential, age, residence, legal-presence status, medical category, test stage, date, vehicle group, brake system, passenger use, cargo, and route. Current Virginia DMV webpages supersede older supplement text when a procedure or transaction changed after May 1, 2023.
Commercial Driver License Exam Readiness: Achieving a passing grade of 80% or higher on state DMV commercial driver knowledge exams requires mastery of federal vehicle inspection procedures, gross vehicle weight ratings (GVWR / GCWR), braking mechanics, and road safety regulations.
