Kentucky CDL General Knowledge study plan

Read the Driving Safely material once end to end, then write a one-page summary of speed management, following distance, and stopping distance rules in your own words.

Memorize the Kentucky and federal limits that appear on the test: 15 mph for railroad crossings and bridges, 55 mph on two-lane highways unless posted otherwise, and the 3-second following rule with added seconds for rain, ice, and heavy loads.

List the six physical conditions that require a driver to slow down or stop (snow, ice, rain, fog, smoke, and dusk/dawn glare) and state the specific action for each.

Practice ten scenario questions on distracted driving, fatigue, and aggressive drivers, and log every miss with the reason you chose the wrong answer.

Work through the railroad-crossing, work-zone, and night-driving sections and write the exact steps for each hazard in checklist form.

Learn the seven-step vehicle inspection sequence (approach, engine compartment, walk-around, lights, brake check, coupling for combinations, and in-cab checks) and recite it from memory.

Demonstrate the inspection sequence out loud on a parked vehicle or a labeled diagram, timing yourself to finish under 10 minutes.

Answer 20 mixed Driving Safely and Vehicle Inspection questions and re-study any sub-topic where you score below 80 percent.

Explain how air pressure builds, where it is stored, and what the low-pressure warning buzzer and light must do at what psi threshold.

Describe the three air brake tests (leakage, low-pressure warning, and spring/parking brake) step by step, including the acceptable pressure-loss limits.

Diagram a tractor-trailer air system showing the supply line, service line, glad hands, relay valve, and spring brakes, and label the function of each part.

Identify the causes of brake fade and the correct downshifting and braking technique for long downgrades.

Complete 25 Air Brakes and Combination Vehicles practice questions and rewrite every missed item as a corrected rule.

State the causes of trailer swing, jackknifing, and off-tracking, and the steering and braking corrections for each.

List the coupling and uncoupling steps in the correct order, including the tug test, landing gear, and air line hookup.

Practice straight-line backing, 90-degree alley docking, and offset backing on a range or simulator, and note which maneuver needs the most work.

Review basic control skills: starting, stopping smoothly, shifting up and down, and steering through turns without off-tracking.

Take a 30-question Combination Vehicles and Basic Control practice set and record your score by sub-topic.

Calculate how cargo weight distribution affects axle loads, and explain why the heaviest part of the load goes over the drive axles.

List the required tie-downs, securement devices, and the aggregate working load limit rule for the cargo you plan to haul.

Describe the differences in handling, braking, and turning for doubles and triples, including the converter dolly and the shutdown procedure for a breakaway.

Explain the front-to-back weight transfer when braking a multi-trailer rig and why the rear trailer can swing out.

Complete 20 Cargo and 15 Doubles/Triples practice questions and correct every miss in writing.

Identify the nine hazard classes by name and number and give one example of a material in each class.

Explain the placarding rules, when placards are required, and what the four-digit UN number and the placard color and symbol communicate.

State the loading and segregation rules for incompatible materials, plus the rules for smoking, parking, and tunnel restrictions.

Describe the special handling of tank vehicles: liquid surge, baffles, bulkheads, and the higher center of gravity in turns.

Complete 30 Hazardous Materials and Tank Vehicle practice questions and rewrite each missed rule as a flashcard.

List the passenger-carrier rules on loading and unloading, standee limits, aisle clearance, and the ban on carrying hazardous materials with passengers.

Explain the school bus loading and unloading procedure, including the danger zone, the stop arm, and the crossing-gate rules.

Describe the school bus inspection items and the railroad-crossing procedure specific to school buses.

Practice shifting techniques: progressive shifting, skip shifting, and downshifting before a downgrade, and explain how each affects control.

Build a hazard-perception routine: scan 12 to 15 seconds ahead, check mirrors every 5 to 8 seconds, and identify escape routes.

Answer 25 mixed Passenger, School Bus, and Shifting practice questions and log the misses.

Take three full-length practice exams under timed conditions and record the score for each domain.

Re-study only the two lowest-scoring domains and retake targeted question sets until each reaches 90 percent.

Recite the pre-trip inspection, air brake tests, and coupling procedure from memory without notes.

Review the Kentucky-specific rules on speed limits, railroad crossings, and school bus stops one final time.

Simulate test-day conditions: sleep, timing, and a quiet setting, then review the answers you missed on the final practice exam.
