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

8 weeks · About 7 hours per week

Week 1

Cargo Securement and Vehicle Loading & Vehicle Systems, Inspection, and Maintenance

  • List and explain each of the four cargo securement tie-down requirements (aggregate working load, attachment points, placement, and restraint type) without notes.

  • Calculate the minimum number of tie-downs required for a 20-foot load and a 40-foot load using the 10-foot rule, and state the aggregate working load limit formula.

  • Identify the five most common securement violations (insufficient tie-downs, damaged straps, loose chains, unsecured dunnage, overloaded axle) and describe the inspection step that catches each one.

  • Walk through a pre-trip inspection sequence for tires, brakes, lights, coupling devices, and emergency equipment, and name the specific defect that would put each item out of service.

  • Explain how weight distribution affects steering axle load, stopping distance, and bridge-formula compliance.

Your checkpoint

A one-page cargo securement and pre-trip inspection checklist written from memory, with tie-down math worked out for two sample loads.

Week 2

Vehicle Inspection and Basic Control & Shifting, Backing, and Turning

  • Demonstrate the seven-step in-cab and walk-around inspection order and state what you are looking for at each stop.

  • Describe the proper start-up procedure for a diesel engine in cold weather, including wait-to-start, oil pressure check, and air pressure build time.

  • Explain the double-clutching sequence and when floating gears is acceptable versus harmful to the transmission.

  • Describe the three backing types (straight-line, offset, and 90-degree) and the GOAL method, including when to use a spotter.

  • Explain off-tracking and calculate how much a 53-foot trailer cuts the corner on a 90-degree right turn.

Your checkpoint

A narrated walkthrough (written script or recorded audio) of a complete pre-trip inspection and one right-turn off-tracking calculation.

Week 3

Space Management and Speed Control & Seeing Hazards and Hazard Perception

  • State the speed and following-distance rules for ideal conditions, rain, fog, and snow, and convert following distance in seconds into feet at 55 mph.

  • Explain the four-second rule and how to adjust it for a 70-foot vehicle, heavy traffic, and downhill grades.

  • Identify the three components of total stopping distance (perception, reaction, braking) and rank the factors that lengthen each one.

  • Classify ten roadside hazards as immediate, emerging, or potential, and describe the escape route for each.

  • Describe how to scan ahead 12-15 seconds in urban versus rural settings and what mirrors should show every 5-8 seconds.

Your checkpoint

A hazard log of 15 real or simulated road situations, each labeled by hazard type, required following distance, and planned escape action.

Week 4

Skid Control, Emergencies, and Crash Procedures & Railroad-Highway Crossings

  • Explain the causes and recovery steps for drive-wheel, steer-wheel, and trailer skids, including what to do and what never to do with the brakes and steering.

  • Describe the procedure for a front-tire blowout at highway speed, including throttle, steering, and braking inputs in order.

  • List the steps for a brake failure, including downshifting, emergency brake use, escape ramps, and what to do if a runaway ramp is unavailable.

  • State the required stopping rules at railroad crossings for placarded hazmat, school buses, and passenger vehicles, and describe the clearance check before crossing.

  • Explain what to do if a vehicle stalls on the tracks and how to report an emergency using the blue ENS sign.

Your checkpoint

A written emergency response card covering skid recovery, blowout, brake failure, and railroad crossing procedures, produced without reference materials.

Week 5

Alcohol, Drugs, and Driver Fitness & Hours of Service and Fatigue

  • State the CDL alcohol limits (0.04 percent for CMV operation, 0.02 percent for the return-to-duty threshold in some contexts, and 0.08 percent for non-CMV), and explain implied consent and refusal consequences.

  • Describe the six drug-testing situations under federal rules (pre-employment, random, reasonable suspicion, post-accident, return-to-duty, follow-up) and the testing window for post-accident alcohol tests.

  • List the seven major categories of controlled substances tested and the penalties for a first positive test, including SAP evaluation and return-to-duty process.

  • Explain the 11-hour driving and 14-hour on-duty limits, the 30-minute break rule, the 60/70-hour limits, and the 34-hour restart.

  • Describe how to complete a paper log and an ELD entry correctly, including the 8-day retention rule and the 24-hour period definition.

Your checkpoint

A completed sample 7-day logbook (paper or ELD printout format) with all duty-status changes, totals, and a post-trip review note.

Week 6

Missouri and Federal Motor Carrier Safety Rules & Alcohol, Drugs, and Driver Fitness

  • Summarize the Missouri CDL disqualification schedule for major and serious traffic offenses, including the length of each disqualification.

  • Explain the difference between out-of-service criteria from the CVSA handbook and Missouri-specific equipment rules, and list five items that trigger an OOS order.

  • Describe the driver qualification file requirements, including the medical examiner's certificate, the MVR check, and the road test or equivalent.

  • Explain the rules for hazardous materials placarding thresholds and the requirement for a hazmat endorsement and background check.

  • Describe what to do during a roadside inspection, including the documents to present and how to handle a citation or OOS order.

Your checkpoint

A 20-question self-quiz on Missouri and federal motor carrier rules, scored and corrected, with a written note on every missed item.

Week 7

Space Management and Speed Control & Cargo Securement and Vehicle Loading & Vehicle Systems, Inspection, and Maintenance

  • Re-derive the following-distance, stopping-distance, and tie-down formulas from memory and apply them to five practice scenarios.

  • Re-inspect a full pre-trip checklist and identify every item that would fail a roadside inspection.

  • Explain how load securement changes braking distance and rollover risk, and describe the effect of a high center of gravity on curve speed.

  • Describe the inspection and maintenance schedule for brakes, tires, lights, and coupling devices, including the daily versus periodic checks.

  • Review all missed questions from weeks 1-6 and write a corrected explanation for each.

Your checkpoint

A corrected error log of every missed practice question from weeks 1-6, with a one-sentence rule restated for each.

Week 8

Vehicle Inspection and Basic Control & Shifting, Backing, and Turning & Space Management and Speed Control & Seeing Hazards and Hazard Perception & Skid Control, Emergencies, and Crash Procedures & Railroad-Highway Crossings & Cargo Securement and Vehicle Loading & Vehicle Systems, Inspection, and Maintenance & Alcohol, Drugs, and Driver Fitness & Hours of Service and Fatigue & Missouri and Federal Motor Carrier Safety Rules

  • Complete three full-length timed practice tests under exam conditions and score at least 85 percent on each.

  • Review every missed item from the practice tests and restate the underlying rule in your own words.

  • Recite the pre-trip inspection sequence, railroad crossing rules, and hours-of-service limits without notes.

  • Confirm test-day logistics: appointment, required identification, and the Missouri CDL document checklist.

Your checkpoint

Three scored practice tests with a final error review summary and a signed readiness statement listing any remaining weak areas.

Milestones

Week 2: Score at least 80 percent on a 25-question quiz covering vehicle inspection, basic control, shifting, backing, and turning, and correctly perform the tie-down math from week 1 without notes.

Week 4: Score at least 80 percent on a 30-question quiz covering space management, hazard perception, skid control, emergencies, and railroad crossings, and produce the emergency response card with no missing steps.
