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.
Major violations
Virginia major violations include 0.04 BAC or higher in a CMV, alcohol or drug operation, test refusal, qualifying hit-and-run, using a CMV for a felony, and false statements on a CDL application. A first major event generally causes one year, or three years while transporting hazardous material; a second or specified drug felony can cause lifetime disqualification.
Serious violations
Serious violations include texting in a CMV, speeding 15 mph or more above the limit, reckless driving, improper or erratic lane change, following too closely, fatal-crash violations, and operation without the required CDL, class, endorsement, or possession. Two within three years cause 60 days and three cause 120 days.
Railroad and out-of-service
Specified railroad-crossing convictions cause 60 days for a first offense, 120 days for a second within three years, and one year for a third within three years. Virginia lists 180 days for a first out-of-service-order conviction and three years for later convictions, subject to the applicable facts.
Alcohol and implied consent
Operating a CMV at 0.04 or more, under the influence, or refusing required testing can disqualify commercial privileges. Virginia also describes immediate and later consequences for chemical-test refusal, and a school-bus driver possessing or consuming alcohol while transporting children faces separate criminal penalties.
Continuing compliance
The holder must maintain the correct class, endorsements, medical record and variances, TSA eligibility for H or X, and every printed restriction. A DMV or FMCSA disqualification, medical problem, cancelled endorsement, or prohibited Clearinghouse status must be resolved before commercial operation resumes.
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.
