Ontario Class A Commercial study plan
Ontario Class A Commercial · Give each week a clear focus.
8 weeks · About 7 hours per week
Commercial vehicle pre-trip inspection and air brake checks
Memorize the full pre-trip inspection sequence for a tractor-trailer and recite it in order without notes by the end of the week.
Identify every component checked in the engine compartment, walk-around, cab, and trailer sections and state the pass/fail criterion for each.
Perform a complete air brake system check on a stationary vehicle: build-up time, governor cut-out, leakage rates, and low-pressure warning activation.
Explain the difference between a service brake check and a parking brake check and demonstrate both in sequence.
Your checkpoint
A self-recorded 20-minute pre-trip and air brake inspection walkthrough scored against a written checklist, with every missed item listed and corrected.
Commercial vehicle pre-trip inspection and air brake checks & Commercial vehicle safety inspections, brakes and emergency procedures
Diagnose common air brake faults (compressor failure, leaking chamber, stuck slack adjuster) from gauge behaviour described in scenarios.
Describe the correct response to brake fade on a long downgrade, including gear selection and use of engine braking.
List the steps for an emergency stop with complete brake loss and for a tire blowout at highway speed.
Identify when a vehicle must be placed out of service for brake defects and cite the defect thresholds you would report.
Your checkpoint
A one-page emergency procedure card covering brake loss, blowout, fire, and runaway, written from memory and checked against reference material.
Coupling, uncoupling and safe operation of combination vehicles
Sequence the full coupling procedure and the full uncoupling procedure, stating the safety check performed at each step.
Explain the fifth wheel locking mechanism and how to verify coupling with a tug test and visual inspection.
Describe the correct landing gear, air line, and electrical connection order during uncoupling and justify the order.
Diagnose three coupling failures (high hook, missed kingpin, unlatched jaw) and state how each is detected before driving.
Your checkpoint
Two written checklists, coupling and uncoupling, each with 10 or more ordered steps and a verification test per step, produced without reference.
Coupling, uncoupling and safe operation of combination vehicles & Sharing the road, hazard perception and defensive driving for heavy vehicles
Explain off-tracking, rearward amplification, and trailer swing and predict how each behaves in a specified turn or lane change.
Demonstrate the correct procedure for a right turn in a combination vehicle, including mirror checks and space management.
Describe speed and space management for a 63,500 kg combination on wet pavement and on a downgrade.
Identify the hazards of passing, being passed, and sharing space with cyclists and pedestrians in an urban setting.
Your checkpoint
A scored 40-question practice set covering coupling and defensive driving, with every wrong answer rewritten as a correct rule statement.
Cargo securement and load limits & Vehicle weights, dimensions and permit requirements
Apply the cargo securement rules to at least five load types and select the correct number and rating of tiedowns for each.
Calculate aggregate working load limit for a tiedown assembly and determine whether a given load is compliant.
Compute axle and gross weight distribution for a sample load and identify when a permit is required for weight.
State Ontario dimensional limits for width, height, and length and identify which oversize loads need an escort or permit.
Your checkpoint
A worked load plan for one sample load showing tiedown count, aggregate WLL, axle weights, and a permit yes/no decision with justification.
Hours of service and daily log requirements
Explain the hours of service limits that apply to a Class A driver and calculate remaining drive and on-duty time from a sample day.
Complete a daily log from a set of time-stamped events, including changing duty status and the 24-hour total.
Identify the documents a driver must carry and the retention period for daily logs and supporting documents.
Describe the consequences of exceeding daily or cycle limits and the correct action when running out of hours away from base.
Your checkpoint
Three daily logs completed from timed event lists, each totalling exactly 24 hours with correct cycle recaps.
Sharing the road, hazard perception and defensive driving for heavy vehicles & Commercial vehicle safety inspections, brakes and emergency procedures
Analyse ten hazard-perception scenarios and state the earliest reasonable action for each.
Describe the inspection and defect-reporting obligations of a driver before, during, and after a trip.
Explain how to respond to a roadside inspection and what to do if a defect is found that places the vehicle out of service.
Describe collision avoidance and post-collision duties, including reporting and securing the scene.
Your checkpoint
A hazard-perception log of ten scenarios, each with the hazard identified, the action chosen, and the reasoning in two sentences.
Commercial vehicle pre-trip inspection and air brake checks & Hours of service and daily log requirements & Cargo securement and load limits & Vehicle weights, dimensions and permit requirements & Coupling, uncoupling and safe operation of combination vehicles & Sharing the road, hazard perception and defensive driving for heavy vehicles & Commercial vehicle safety inspections, brakes and emergency procedures
Complete two full-length timed practice exams and score at least 85 percent on each.
Re-drill every weak area flagged by the practice exams until each is answered correctly twice in a row.
Recite the pre-trip inspection and air brake check one final time under time pressure.
Review the emergency procedure card, coupling checklists, and load plan for final accuracy.
Your checkpoint
Two timed practice exam score sheets with a written remediation list showing every missed item retested and passed.
Milestones
Week 2: Recite the complete pre-trip inspection and air brake check from memory with no more than two missed items, and pass a 20-question domain 1 quiz at 80 percent or better.
Week 4: Produce both coupling and uncoupling checklists from memory and score 80 percent or better on a mixed domains 5 and 6 practice set.
Week 6: Complete three accurate 24-hour daily logs and a compliant load plan with correct tiedown count and permit decision.
Week 8: Score 85 percent or better on two full-length timed practice exams and show a cleared remediation list with no outstanding weak areas.
