Louisiana Class D Chauffeur's License Exam

The test focuses on Louisiana-specific rules and safety practices for obtaining a Class D chauffeur's license, which permits operation of vehicles or combinations weighing 10,001 to 26,001 pounds (excluding hazardous materials). Topics include headlight usage (dimming high beams at 500 feet from oncoming traffic and 200 feet when following), emergency braking techniques (controlled braking without locking wheels, stab braking), air brake systems (safety valve set at 150 psi, low air pressure warnings, spring brakes, compressor governor), vehicle dimensions (maximum width 8 feet for vehicles except buses at 8 feet 6 inches, height 13 feet 6 inches), load securing and extensions (no more than 3 feet beyond rear except for poles/logs at 15 feet, red flags/lights for overhanging loads), speed limits (70 mph on rural highways, 55 mph for school buses), emergency equipment (3 flares/reflectors/red lanterns and 2 red flags, fire extinguishers like 10-BC for explosives or tow trucks), inspection steps (air brake checks for pressure drop, parking brake valve closure at 20-45 psi), and general safety (following distances for trucks, rear view mirror visibility to 200 feet, warning signal placement at breakdowns). Multiple-choice options test knowledge of exceptions, calculations (e.g., total stopping distance as perception + reaction + brake lag + effective braking), and scenarios. Written questions require recalling specifics like warning equipment types, air flow delays in brakes (0.5 seconds), or load projection limits.
