This commercial driver study guide covers relevant Federal Motor Carrier Safety Administration (FMCSA) Entry-Level Driver Training (ELDT) concepts and California commercial driver knowledge topics. Review the regulations, procedures, and safety checklists below as part of your CDL and commercial learner permit (CLP) preparation.
Prohibited practices
Do not fuel with passengers aboard when prohibited, tow or push improperly, carry unauthorized hazardous articles, block exits, allow riders in unsafe locations, or leave the vehicle unsecured. Apply the exact current rule for the operation and vehicle type.
Decide whether to evacuate
Evacuate for fire, smoke, dangerous leaks, unstable position, threat of collision, or another condition where staying is more dangerous. If the safest action is to keep passengers aboard, move or shelter only under a deliberate plan.
Evacuation control
Stop, secure the vehicle, notify responders, choose exits away from danger, give clear commands, assign able assistants, account for passengers, and move everyone to a safe gathering area. Protect mobility-limited passengers without blocking the flow.
Fire and smoke
Stop away from traffic, structures, fuel, and overhead hazards when possible. Shut down safely, evacuate upwind, call emergency services, and use an extinguisher only on a small controllable fire with an escape path.
Breakdown or crash
Activate warnings, assess injuries and hazards, contact emergency services and dispatch, place warning devices as required, and keep passengers protected from traffic. Do not unload people into a more dangerous location without a plan.
Medical and behavioral events
Stop safely before providing assistance. Use trained first aid, request medical help, protect privacy, and avoid physical confrontation unless immediate safety and training justify action. Preserve incident facts for reporting.
Scenario
Smoke enters the rear of a bus. The driver stops upwind away from traffic, secures the vehicle, uses front and side exits away from smoke, assigns an assistant to lead passengers to a safe area, accounts for everyone, and calls responders.
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.
