Illinois CDL General Knowledge study plan

Illinois CDL General Knowledge · Give each week a clear focus.

8 weeks · About 6 hours per week

Week 1

Hazardous Materials, Cargo, and Vehicle Safety

Read the Hazardous Materials, Cargo, and Vehicle Safety domain material once end to end, then rewrite the cargo-securement rules (tiedown count, working load limit, aggregate WLL vs. cargo weight) in your own words from memory.
Build a one-page reference sheet listing the placard classes, the 1,001-pound rule, and the segregation table logic, then quiz yourself on it until you can name all hazard classes without notes.
List every inspection item a driver must check before hauling hazardous materials (shipping papers, placards, leaks, tires, brakes) and explain in writing why each one matters.
Complete 30 practice questions on this domain and log every miss with the reason you missed it.

A handwritten or typed two-page hazardous materials and cargo cheat sheet plus a scored 30-question practice set with a written error log.

Week 2

Memorize the seven-step pre-trip inspection sequence and recite it aloud in order without looking at notes.
Practice a full pre-trip walk-around on an actual or simulated vehicle, calling out each component and its defect criteria within 20 minutes.
Explain the difference between the pre-trip, en-route, and post-trip inspection requirements and when each is mandatory.
Drill 25 mixed questions covering cargo securement and inspection, then re-answer last week's missed items to confirm retention.

A timed 20-minute pre-trip walk-around performed from memory with a self-scored checklist covering at least 40 components.

Week 3

Summarize the rules for loading cargo so weight is distributed within axle and gross limits, and calculate three sample load-distribution problems by hand.
Describe how a heavy load changes stopping distance, center of gravity, and rollover risk, and write two sentences on each effect.
Explain the correct procedures for backing, turning wide, and starting on a hill with a loaded vehicle.
Complete 30 practice questions spanning cargo safety and basic vehicle control and record your accuracy by subtopic.

Three worked weight-distribution calculations with correct answers plus a subtopic accuracy table from the 30-question set.

Week 4

Explain the correct gear for going down a long grade and state why coasting and neutral are prohibited, in writing.
Describe the double-clutching and progressive shifting procedures step by step and practice the sequence on a manual transmission if available.
Identify the rpm range for upshifting and downshifting and explain how to avoid over-revving or lugging the engine.
Pass a 25-question checkpoint covering domains 1, 2, 3, and 12 with at least 85 percent accuracy.

A 25-question checkpoint quiz scored at 85 percent or better, with every missed question rewritten as a corrected flashcard.

Week 5

Define the hazard-perception process (scan, identify, predict, decide, execute) and apply it to five written road scenarios.
List the communication tools a driver uses (turn signals, four-way flashers, horn, headlights, brake lights) and state when each is appropriate.
Calculate following distance using the one-second-per-ten-feet rule for three vehicle lengths and speeds.
Explain how speed affects stopping distance and list the conditions that require reducing speed below the posted limit.

Five written hazard scenarios scored against the scan-predict-decide-execute model plus three correct following-distance calculations.

Week 6

Describe the space-management rules for following, lane changing, merging, and passing, including the space needed in front, behind, and to the sides.
Explain the blind-spot zones around a large vehicle and how to check them before a maneuver.
Solve five problems on stopping distance and space cushions at different speeds and road conditions.
Complete 30 practice questions on speed control and space management and log accuracy.

Five solved space and stopping-distance problems plus a scored 30-question practice set with an accuracy summary.

Week 7

List the vision and visibility limits of night driving and the countermeasures for each (speed reduction, headlight use, glare handling).
Explain winter driving procedures including chain use, skid recovery, and bridge/black-ice awareness, and describe the pre-trip checks specific to cold weather.
Describe hot-weather risks such as tire blowouts, brake fade, and engine overheating, and the preventive actions for each.
Explain mountain driving rules for downgrades, escape ramps, and engine braking, and state why brakes must not be continuously applied.

A four-column conditions chart (night, winter, hot, mountain) listing at least five hazards and five countermeasures per column.

Week 8

Re-take a full-length mixed practice exam covering all 12 domains under timed conditions and score at least 85 percent.
Review every missed item from the full exam and write the correct rule in your own words for each.
Re-perform the pre-trip walk-around from memory and recite the hazardous materials and cargo rules without notes.
Build a final one-page summary of the ten facts you are most likely to forget and read it daily before test day.

A timed full-length practice exam scored at 85 percent or better plus a corrected error log and a one-page final review sheet.

Week 2: Can recite the seven-step pre-trip sequence and the hazardous materials placard classes from memory without notes.

Week 4: Scores 85 percent or better on a 25-question checkpoint covering domains 1, 2, 3, and 12.

Week 6: Correctly solves all five space and stopping-distance problems and scores 80 percent or better on the domains 6 and 7 practice set.

Week 8: Scores 85 percent or better on a timed full-length mixed exam across all 12 domains and has a complete corrected error log.
