Label a hand-drawn air brake system diagram with compressor, governor, reservoir, foot valve, relay valve, and spring brakes.

Walk through a full seven-step vehicle inspection sequence and state the pass/fail criterion for each step.

Identify at least ten out-of-service defects on a written defect list and explain why each removes the vehicle from service.

Describe the symptoms, causes, and safe response for brake fade, dragging brakes, and a malfunctioning ABS warning lamp.

Explain how to check coolant, oil, power steering fluid, and belt condition, and what a driver must do if a leak is found.

Recite the procedure for handling a vehicle that fails inspection at a roadside check.

Describe the correct start-up and shutdown sequence for a heavy vehicle, including parking brake and wheel chock use.

Explain proper use of the clutch, accelerator, and brakes when starting from a stop on a grade, and describe rollback limits.

State the rpm range for upshifting and downshifting and explain why progressive shifting saves fuel.

Describe the consequences of skipping gears, coasting in neutral, and riding the clutch.

Explain how to brake on a long downgrade using engine braking and snubbing rather than continuous brake pressure.

Define the proper following distance for a loaded combination vehicle at highway speed and state the seconds-based formula.

Explain how total stopping distance is built from perception, reaction, brake lag, and braking distance, and how speed affects each.

Describe the correct use of mirrors, including blind spot zones and when to check them during a lane change.

Explain how to signal, and when to use four-way flashers, headlights, and horn to communicate with other drivers.

Identify the space needed for lane changes, merges, and right turns, including the off-tracking path of a long wheelbase vehicle.

Describe the correct response to a tire blowout at highway speed, including steering and throttle inputs.

Explain how to handle brake failure, including downshifting, using the emergency brake, and looking for an escape route.

Describe the hazards of driving in fog, heavy rain, and high wind, and state the speed and following distance adjustments for each.

Explain railroad crossing procedures, including when stopping is required for a bus or hazardous materials vehicle.

Describe how to recognize and respond to a driver ahead who is drifting, braking erratically, or distracted.

Explain the causes of a drive-wheel skid and the correct recovery steps, including releasing the brakes and steering into the skid.

Describe the difference between front-wheel and rear-wheel skids and the recovery technique for each.

Explain how to prevent skids on wet, icy, and gravel surfaces, including speed and braking adjustments.

State the working load limit concept and how to determine the number of tiedowns required for a given load.

Describe proper securement methods for aggregate, steel coils, logs, and vehicles, and explain why each method differs.

Explain cargo weight distribution, axle weight limits, and the effect of an improperly loaded trailer on steering and braking.

Describe the pre-trip and en-route checks required for cargo, including checking tiedowns within the first 50 miles.

State the rules for transporting passengers, including prohibited items, aisle clearance, and emergency exit access.

Describe the special handling requirements for hazardous materials placarding, parking, and route restrictions.

Explain the rules for transporting oversize loads, including permits, flags, and lighting requirements.

Describe the CDL disqualification rules, including serious traffic violations and out-of-service orders.

Explain the inspection, repair, and maintenance reporting duties of the driver, including the DVIR requirement.

Complete a full-length timed practice exam under test conditions and record the score for every domain.

Review every missed question from the full practice exam and rewrite the underlying rule in your own words.
