Explanation:

The low air pressure warning must activate by 60 PSI, and a full system test generally requires the system to be above that threshold. This ensures there is enough air pressure to safely test the brake system for leaks or failures.

Explanation:

The driver is legally required to know and follow the carrier’s safety plan, including inspections, hours of service, cargo securement, and more. Drivers must also be aware of legal requirements and company policies.

Explanation:

According to the guide, trucks and trailers with a registered weight of 11,794 kg or more must be inspected annually under the Vehicle Inspection Program. This ensures the vehicle meets minimum mechanical and safety standards.

Explanation:

The pre-trip inspection (circle check) is designed to identify mechanical or safety issues before the trip begins, reducing the risk of on-road incidents or failures.

Explanation:

During daylight hours, any load that extends more than 1.5 metres beyond the rear of the vehicle must be marked with a red flag. This improves visibility for other road users and helps prevent collisions.

Explanation:

Commercial vehicles are required to carry specific safety equipment, including a fire extinguisher, warning triangles, and a first aid kit. These items help manage emergencies or breakdowns safely.

Explanation:

Drivers of regulated commercial vehicles (as defined by provincial or federal law) must carry a valid trip inspection report and inspection schedule with them while operating the vehicle. The report must be no more than 24 hours old and include all required components. Failing to do so may result in penalties.

Explanation:

To apply for a Class 1 commercial licence, which allows the operation of most heavy vehicles, a driver must be at least 18 years old and have a non-GDL (non-probationary) Class 5 licence. This ensures they have adequate driving experience before handling more complex commercial vehicles.

Explanation:

GVW stands for Gross Vehicle Weight, which includes the weight of the vehicle plus its load. Commercial vehicle regulations often include restrictions based on GVW to protect roads and ensure safety.

Explanation:

Step 1 in the trip air brake inspection is to chock the wheels, ensuring the vehicle doesn’t roll during testing. This is a vital safety measure, especially when the brakes may be released during the inspection.

Explanation:

Defects are classified as major or minor. A minor defect allows driving if reported, while a major defect requires the vehicle to be taken out of service until repaired.

Explanation:

The guide states that drivers transporting dangerous goods must complete specific training and carry valid certification under federal or provincial legislation. This ensures they understand the classification, handling, documentation, labeling, and emergency procedures for transporting hazardous materials safely.

Explanation:

A driver must complete a recognized air brake course to get a “Q” endorsement added to their licence. This endorsement allows the driver to operate commercial vehicles equipped with full air brake systems, which are common in large trucks and buses. Without it, drivers cannot legally operate vehicles that rely solely on air brakes.

Explanation:

If a load extends more than 1.5 meters beyond the rear of the vehicle, the handbook requires it to be marked with a red light at night to alert other road users. During daylight hours, a red flag may be used instead. This ensures that the overhanging part of the load is visible and reduces the chance of a collision.

Explanation:

If the compressor cannot build pressure quickly, it suggests either a faulty compressor or a leak in the air system. This must be repaired before the vehicle can be safely operated.

Explanation:

The NSC was created to provide uniform safety performance standards across Canada for commercial carriers. It includes rules for vehicle inspections, hours of service, cargo securement, and more, ensuring consistent enforcement nationwide.

Explanation:

The guide is clear: A vehicle must not be operated if a major defect is found. A defect is considered "major" if it poses a risk to safety. Continuing to drive a vehicle in this condition is both unsafe and illegal.

Explanation:

The steering axle tires must have a minimum tread depth of 3.2 mm. Tires with insufficient tread are dangerous because they reduce traction, especially in wet conditions, increasing the risk of skidding or hydroplaning.

Explanation:

Safe driving depends on your ability to detect and respond to hazards. The guide outlines a three-step stopping process:See the hazard

Think about how to respond (e.g., stop or steer away)

Do by taking appropriate action (brake, steer, slow down).
This model encourages defensive, proactive driving to reduce the risk of collisions.

Explanation:

Large commercial vehicles are heavier and require more time and space to stop safely than smaller passenger vehicles. The handbook recommends at least a four-second following distance to ensure there is enough room to react and stop in case the vehicle in front suddenly slows down or stops. This distance should be increased in poor weather or low visibility conditions.

Explanation:

The circle check, or pre-trip inspection, is a required procedure that helps drivers identify mechanical defects or safety issues before getting on the road. This includes checking brakes, tires, lights, fluids, and securing cargo. Completing a thorough pre-trip inspection is part of a carrier’s legal maintenance responsibilities.

Explanation:

School buses must undergo inspection every six months, due to their heavy usage and the responsibility of transporting children. This semi-annual check helps ensure their mechanical and safety systems are working properly.

Explanation:

While the posted speed limit always applies, many commercial carriers have policies that limit long combination vehicles (LCVs) to 100 km/h or less. This is due to the increased stopping distances and reduced maneuverability of longer vehicle combinations, making it safer to drive at slightly reduced speeds.

Explanation:

A post-trip inspection is necessary after every trip, regardless of trip length. This helps identify any damage or safety defects that occurred during the trip. By doing the inspection right after the trip, the driver ensures that necessary repairs or servicing can be done before the next shift, minimizing the risk of breakdowns or safety hazards.

Explanation:

Off-tracking occurs when the rear wheels of a truck or trailer follow a different path than the front wheels when turning. This is especially noticeable in tight turns and can cause the trailer to hit curbs or objects near the road edge. Commercial drivers must adjust their turning techniques to account for this.

Explanation:

Drivers are legally required to report both minor and major defects. This ensures the carrier can promptly address safety issues, helping prevent breakdowns, collisions, or enforcement penalties.

Explanation:

A circle check is a type of pre-trip inspection where the driver walks around the vehicle to examine its tires, lights, brakes, mirrors, and other components. This visual inspection helps spot defects before the vehicle is operated.

Explanation:

The low air pressure warning system must activate before pressure drops below 60 PSI. If it doesn’t, the system is faulty, and the vehicle cannot be driven until the defect is fixed, as required by law.

Explanation:

A driver is exempt from completing a daily log if they:

start and end the day at the same location,

stay within a 160 km radius,

have no more than 15 hours on duty,

and the employer maintains accurate time records.

Explanation:

If the air pressure drops rapidly when brakes are applied, it indicates a possible leak or malfunction in the air brake system. This should be reported and repaired before continuing to drive, as it may lead to brake failure.
