MN CDL General Knowledge study plan

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

8 weeks · About 6 hours per week

Week 1

Vehicle Inspection and Basic Control & Vehicle Systems, Inspection, and Maintenance

Walk the seven-step vehicle inspection in order out loud, naming each part checked and the defect that would put the vehicle out of service.
Trace the full air-brake system from compressor to brake chambers, and explain what happens during a low-pressure warning and a spring-brake application.
Describe the correct procedure for checking coolant, oil, tire tread depth, and belt condition, and state the rejection threshold for each.
Explain how to test the service brake, parking brake, and emergency brake during a pre-trip inspection and what result counts as a failure.

A one-page written pre-trip checklist in your own words with at least 20 items and the out-of-service threshold for each.

Week 2

Demonstrate in a lot or with a trainer the clutch-and-gear sequence for starting from a stop on a grade without rolling backward.
Explain the double-clutch method and when floating gears is unsafe or prohibited.
Describe the mirror setup and visual reference points used to back straight and to back into a dock on the driver side.
Explain the off-tracking path of a tractor-trailer in a right turn and how much extra lane space to allow.
Identify the conditions under which a driver must stop and re-check before completing a backing maneuver.

A written turn-and-backing worksheet explaining off-tracking, mirror use, and the spotter/signal rules, plus a verbal walkthrough of a grade start.

Week 3

State the required following distance formula for a loaded tractor-trailer at highway speed and apply it to three sample speeds.
Explain how speed affects stopping distance, and compute the approximate increase in stopping distance when speed doubles.
List the situations that require a reduced speed below the posted limit, including curves, rain, fog, and heavy traffic.
Describe when headlights, four-way flashers, and horn use are required or prohibited.
Identify the most common driver distractions and the specific habit you will use to eliminate phone use while driving.

A following-distance and stopping-distance table for 35, 45, 55, and 65 mph, with the rule cited for each row.

Week 4

Explain the correct response to a front-tire blowout, a rear-tire blowout, and a hydraulic brake failure, step by step.
Describe how to recognize and recover from a drive-wheel skid, a steer-wheel skid, and a trailer jackknife.
Explain the role of brakes and steering in causing versus correcting a skid, and why locking wheels makes recovery harder.
List the escape routes and decision points you would look for when approaching a steep downgrade or a work zone.
Describe the correct use of an escape ramp and when it is the right choice.

A written emergency-response card covering blowout, brake failure, and three skid types, each in five steps or fewer.

Week 5

Explain how weight distribution affects steering axle load, and describe the consequence of an overloaded or underloaded front axle.
List the four tie-down requirements for cargo, including the aggregate working load limit rule and the number of tie-downs required by cargo length.
Describe how to inspect and secure a load before departure and after the first 50 miles.
Explain the required actions at a passive and an active railroad crossing, including the stop, look, and listen sequence and the gear you should be in.
Identify the situations at a crossing that require you to stop even when no train is visible.

A cargo securement and crossing checklist with at least 15 checkpoints, written from memory and then corrected against your study material.

Week 6

Describe the warning signs of brake, tire, steering, and lighting problems and the action required for each.
Explain the 11-hour driving limit, the 14-hour window, the 30-minute break, and the 60/70-hour limits, and compute a sample day that stays legal.
Describe how to complete a paper log or ELD entry correctly for a day that includes loading, driving, and a break.
List the signs of fatigue and the countermeasures that work versus those that do not.
Explain the rules for adverse driving conditions and the short-haul exception and when each applies.

A completed sample log day plus a written explanation of why each entry is legal under the hours-of-service rules.

Week 7

State the CDL alcohol and drug thresholds, the consequences of a refusal, and the length of disqualification for a first offense.
Explain how over-the-counter and prescription medications can affect driving fitness and what to do before driving.
Describe the required actions when sharing the road with pedestrians, cyclists, motorcycles, and emergency vehicles.
Explain the rules for passing, being passed, and following a school bus and a commercial vehicle.
Describe safe behavior in work zones, at night, and in mountain driving.

A two-page summary covering impairment rules and shared-road rules, with at least 20 specific facts you can state without notes.

Week 8

Complete a full-length practice test under timed conditions and score your missed items by domain.
Re-study only the domains where you scored below 85 percent and rewrite those rules in your own words.
Recite the pre-trip inspection sequence and the emergency-response card from memory without prompts.
Review the following-distance, stopping-distance, and hours-of-service computations one final time.
Confirm your test-day logistics, including what identification and documents the MN DVS testing site requires.

A scored practice test with a written list of every missed item, the correct rule, and a note on why you missed it.

Week 2: Can perform and explain the seven-step inspection and a grade start without notes, and can describe off-tracking in a right turn.

Week 4: Scores at least 85 percent on a practice set covering domains 1, 3, and 4, and can state the following-distance rule for three speeds.

Week 6: Can write a legal sample log day and can list the cargo tie-down and railroad crossing requirements from memory.

Week 8: Scores at least 90 percent on a full-length timed practice test, with no domain below 85 percent.
