Identify and describe five specific driving hazards (work zones, sharp curves, railroad crossings, fog, night driving) and list the concrete action a driver takes for each.

Summarize the rules for sharing the road with bicycles, pedestrians, motorcycles, and four-wheelers, including the 'No-Zone' blind spots and when a truck must yield.

Complete at least 40 practice questions covering Driving Safely and log every missed question with the reason it was missed.

Practice the pre-trip sequence for basic controls: clutch, gear selection, steering, and braking, and write out the correct procedure for starting from a stop on a hill without rolling back.

Explain the difference between controlled braking, stab braking, and brake fade, and state when each is used on a downgrade.

Describe the procedures for driving through curves, merging onto a freeway, and backing up, and list the three correct backing methods and the minimum number of people required as spotters.

Identify the causes and correction of skids (drive-wheel, front-wheel, and trailer skids) and write the counter-steering recovery steps for each.

Answer 50 mixed practice questions from Driving Safely and Basic Control and score at least 85 percent.

Learn the cargo securement rules: working load limits, the minimum number of tiedowns, aggregate working load limit requirements, and the specific rules for securing logs, steel, and vehicles.

Explain how weight distribution affects axle loading and steering, and describe how to check that cargo is balanced and that the vehicle is not overloaded on any axle.

List the cargo that requires special handling or permits, including oversize and overweight loads, and state the consequences of an uncovered or leaking load.

Perform a full pre-trip inspection walk-around (engine compartment, cab, lights, coupling, brakes, tires, cargo) and narrate each item out loud in the order the examiner expects.

Complete 40 practice questions on Transporting Cargo and Vehicle Inspection and log every missed item.

Explain how air brakes work end to end: compressor, governor, reservoirs, foot valve, slack adjusters, chambers, and the spring and parking brakes, and describe what each gauge and warning tells you.

Describe the air brake pre-trip checks: static leak test, applied leak test, low-pressure warning test, and the spring brake test, including the pressure limits and pass/fail criteria.

Identify the causes of brake fade and the correct use of the snub braking method on long downgrades.

Explain combination vehicle coupling and uncoupling in order, including the fifth wheel, kingpin, landing gear, air lines, and the tug test, and list the steps of the walk-around inspection after coupling.

Pass a 50-question practice set on Air Brakes and Combination Vehicles with a score of at least 85 percent.

Explain how a converter dolly connects the first and second trailers, and describe the correct order for coupling and uncoupling a set of doubles, including the air line and electrical connections.

Describe the off-tracking, sway, and rearward amplification differences between singles, doubles, and triples, and state the speed and lane-position adjustments each requires.

Explain how to check that each trailer's brakes are working and how to test the dolly's brakes, and describe what to do if a trailer breaks away.

Describe the correct procedures for turning wide, changing lanes, and backing a combination vehicle, and explain why backing doubles and triples should be avoided in normal operations.

Complete 40 practice questions on Doubles and Triples and log the reasoning for every missed item.

Explain why tank vehicles have a high center of gravity and how liquid surge affects steering, braking, and rollover risk, and describe how to control it with smooth inputs and reduced speed.

Describe the special driving rules for tankers: slowing before curves, avoiding sudden lane changes, braking earlier, and managing the ride height and baffles.

List the tank vehicle inspection items: tank shell, dome cover, baffles, valves, vents, ground loading, hoses, and the markings required for the cargo being carried.

Explain the difference between smooth-bore and baffled tanks and between liquid and dry bulk tanks, and describe what happens to surge in each.

Answer 40 practice questions on Tank Vehicles and score at least 85 percent.

Identify the nine hazard classes and the placarding rules: when placards are required, which placards to use, and how to read the hazard class number and the four-digit UN number on a placard.

Explain the shipping paper requirements: the basic description, emergency response information, and the difference between the shipping paper and the emergency response guidebook.

Describe the rules for loading and unloading hazardous materials, including segregation, smoking, parking, tunnels, and the special rules for explosives and radioactive materials.

Explain the emergency response for a hazmat spill or fire: what to do first, how to use the emergency response guidebook, and the reporting requirements.

Complete 50 practice questions on Hazardous Materials and score at least 85 percent.

Describe the school bus pre-trip items that differ from a general pre-trip, including the stop arm, crossing gate, flashing lights, emergency exits, and the passenger seating and aisle requirements.

Explain the loading and unloading procedure: the stop, the mirror check, the student crossing procedure, the danger zone, and the rules for students who must cross the road.

Describe the railroad crossing procedure for school buses and the rules for driving in bad weather and on ice and snow with passengers on board.

Take a full-length timed practice exam of at least 100 mixed questions covering all 10 domains and score at least 90 percent.

Review every missed question from the full-length exam and write a correction note for each one.
