Let’s face it—commercial driver handbooks can be overwhelming. Our practice tests help break the information down into manageable, scenario-based questions that teach you how to apply knowledge on the road and during your exam.
Commercial Vehicle Road Signs & Signals
Understanding and reacting to signs is crucial for large vehicle operators. You’ll be tested on:
Regulatory Signs: Speed limits, stop/yield, lane restrictions, no U-turns
Warning Signs: Steep hills, sharp curves, slippery roads, and railway crossings
Guide & Information Signs: Route markers, rest areas, emergency services
✅ Driver Tip: Learn the shape and color of each sign type—they’ll help you react faster behind the wheel.
Defensive Driving for Commercial Vehicles
Professional drivers must be prepared for anything. You’ll learn:
Safe following distances for large vehicles
How to manage blind spots
Defensive lane positioning and escape routes
Anticipating risks from weather, traffic, and other drivers
Avoiding high-risk situations like sudden stops or sharp turns
✅ Test Tip: Knowledge tests often include defensive driving scenarios—especially involving heavy loads and high-speed roads.
Intersections, Turns & Lane Use
Driving large commercial trucks requires advanced control in tight spaces. Expect questions on:
Wide turns and off-tracking
Yielding at 4-way and uncontrolled intersections
Lane discipline for multi-lane roads
Proper use of turn lanes and merging procedures
✅ Test Tip: Know how to signal early, use mirrors properly, and handle roundabouts in a commercial vehicle.
Vehicle Safety Equipment & Pre-Trip Inspections
You’ll be tested on mandatory checks and legal requirements:
Headlights, turn signals, and brake lights
Air brakes and emergency brake systems
Mirrors, reflectors, and horn usage
Pre-trip inspection steps (TCLOCS for trucks)
Vehicle condition reports (VCRs)
✅ Test Tip: Most provinces require you to know the air brake system inside out. Study it thoroughly.
Loading, Unloading & Cargo Safety
Understanding cargo securement is critical. Practice tests cover:
Legal weight limits and axle loading
Load balance and distribution
Tarping and tying down cargo securely
Hauling hazardous materials (basic awareness)
Transporting passengers (for Class 2 and 4)
✅ Test Tip: Know the difference between direct and indirect tie-downs and their minimum strength requirements.
Weather, Road Conditions & Emergency Maneuvers
Large vehicles behave differently in rain, snow, and wind. You’ll be tested on:
Adjusting speed and braking in poor weather
Avoiding hydroplaning and jackknifing
Proper use of chains and winter tires
Emergency lane changes and evasive maneuvers
✅ Test Tip: Practice questions may describe real-life conditions and ask what action you’d take as a driver.
