California CDL General Knowledge Test study plan
California CDL General Knowledge Test · Give each week a clear focus.
8 weeks · About 6 hours per week
Driving Safely & Vehicle Inspection and Basic Control
Memorize the following-distance rules for dry, wet, icy, and heavy-load conditions and state the speed at which each applies
List the factors that increase total stopping distance (perception, reaction, brake lag, braking distance) and rank them by contribution
Recite the seven-step pre-trip inspection sequence in the correct order without notes
Define the space-management rules for lane position, following, and being followed, and explain when to drop speed by 10 mph or more
Your checkpoint
One-page handwritten rule sheet covering following distance, stopping distance, and the seven inspection steps, scored against the answer key at 90% or better
Driving Safely & Vehicle Inspection and Basic Control
Explain lane-control, passing, and being-passed procedures including when passing is prohibited
Describe visual-search habits for night driving, fog, rain, and railroad crossings and state the speed/lighting adjustments each requires
Perform the basic-control maneuvers verbally: straight-line backing, 45-degree backing, lane changes, and right/left turns without off-tracking
Identify the driver-distraction and fatigue conditions most often cited in crash causes and the countermeasure for each
Your checkpoint
Complete a 60-question practice set on Domains 1 and 3 with a score of 80% or higher, and log every missed item with its correction
Vehicle Inspection and Basic Control & Transporting Cargo Safely
Demonstrate the full pre-trip inspection out loud on a vehicle or a mock-up in under 12 minutes, naming each part and its defect criteria
Explain the air-brake leakage and pressure-build checks and the readings that fail them
Compute legal axle and gross weight limits and detect an overload from a sample weight ticket
Describe how to recognize, before driving, that a load is improperly distributed or under-secured
Your checkpoint
Timed self-run of the complete pre-trip inspection performed start-to-finish with no missed steps on the checklist
Transporting Cargo Safely
Match cargo securement requirements to load type: tiedown count, working load limit, and aggregate strength
Explain the in-transit cargo inspection rule and the conditions that require a re-check within the first 50 miles
List the cargo-related paperwork and markings a driver must verify before departure
Describe safe handling for special loads, including sealed, placarded, and high-center-of-gravity freight
Your checkpoint
Completed cargo worksheet of 25 load scenarios, each labeled secure/unsafe with the rule cited, at 88% accuracy or better
Hazard Perception and Emergency Procedures
Describe the scanning pattern and following-distance adjustments required in construction zones, heavy traffic, and adverse weather
State the correct response sequence for a front-tire blowout, a skid, and a brake-fade emergency
Explain the emergency procedures for vehicle fire, including when to fight it and when to evacuate
Identify the hazards of downed power lines, spilled cargo, and stopped traffic on the shoulder, and the safe action for each
Your checkpoint
Set of 12 emergency-procedure flashcards written from memory, each checked against the reference material with zero factual errors
Vehicle Systems, Hours of Service, and Non-Driving Activities & Hazard Perception and Emergency Procedures
Explain how the braking, electrical, cooling, and tire systems fail and the warning signs a driver must act on
State the hours-of-service driving, on-duty, and weekly limits plus the required break and reset rules
Solve six hours-of-service log scenarios and identify which ones are in violation
Describe the rules and consequences for alcohol, controlled substances, and medical conditions, and the driver's self-reporting duties
Your checkpoint
Hours-of-service scenario worksheet with all six logs scored correctly, including the specific rule violated in each non-compliant log
Driving Safely & Vehicle Inspection and Basic Control & Vehicle Systems, Hours of Service, and Non-Driving Activities
Take three timed mixed-domain practice tests and record the score for each domain separately
Rank the three weakest sub-topics and re-study each for 45 minutes
Re-explain from memory any rule missed twice across the three tests
Reduce average test completion time while holding accuracy above 85%
Your checkpoint
Error log of every missed question with the corrected rule, plus a ranked weak-area list showing improvement between test one and test three
Transporting Cargo Safely & Hazard Perception and Emergency Procedures
Complete two full-length timed simulations covering all five domains and score 90% or higher on each
Review every remaining error from the log and close out each one with a written correction
Recite the pre-trip inspection sequence and the emergency procedures one final time without notes
Verify logistics: appointment time, required documents, and the vehicle you will test in
Your checkpoint
Two full-length simulation score sheets at 90% or better with a fully closed-out error log
Milestones
Week 2: Can recite the seven-step pre-trip inspection order and both following-distance and stopping-distance rules without notes
Week 4: Scores 85% or higher on a mixed Domain 1, 2, and 3 practice test and can perform the full inspection in under 12 minutes
Week 6: Scores 80% or higher on a Domain 4 and 5 practice test and solves all six hours-of-service scenarios correctly
Week 8: Two consecutive full-length timed simulations at 90% or better with zero repeated errors from the log
