Class 1 Mock
#1. Which of the following types of commercial vehicles are required to carry fire extinguishers?
The following types of vehicles are required to carry one fire extinguisher: (a) school buses, (b) public passenger vehicles, and (c) limited passenger vehicles that have an authorized seating capacity of more than 10. Vehicles transporting explosives are required to carry two fire extinguishers.
#2. Drivers must hold an industrial air brake endorsement if they will be __________ on industrial roads.
Very few drivers require an industrial air brake endorsement. You need an industrial endorsement only if you’ll be operating unlicensed vehicles that are equipped with air brakes and are used to transport natural resources on industrial roads. (An industrial road is any road that exists for the transportation of natural resources, machinery, materials or personnel. Industrial roads include all company bridges, wharves and log dumps.) You don’t need an industrial air brake endorsement to operate skidders, loaders, graders or yarders on industrial roads.
#3. Under ideal driving conditions, passenger cars and light trucks should maintain a following distance of at least ________ behind the vehicle ahead.
Drivers of passenger cars and light trucks should maintain a following distance of at least two seconds behind the vehicle ahead. Drivers of buses, trucks, or other heavy vehicles should maintain a following distance of at least five seconds. If driving conditions are less than ideal, they should increase their following distance still further.
#4. When must an aggregate load be covered?
You must use a cover or tarp to secure an aggregate load if the load is likely to bounce, blow or drop from the moving vehicle
#5. When pulling out from an alley, you must
Bear in mind that pedestrians don’t expect motor vehicles to be driving on the sidewalk. If you are entering a main road from an alley, lane or side road, you must stop before the sidewalk or sidewalk area and yield to pedestrians and other vehicles before you may proceed.
#6. How can you tell how much air pressure is in the service reservoirs?
The reservoir pressure gauge is connected to the service reservoir. It shows how much air pressure is in the reservoir. In a dual-circuit system, there will be either two gauges, one for each circuit’s service reservoir, or a single gauge with two needles. The gauges are mounted on the instrument panel so you can monitor reservoir air pressures while you drive.
#7. As a commercial driver, you are expected to practice
As a commercial driver, you are expected to practice safe driving. To obtain a commercial licence, you must pass a knowledge test on safe driving practices and a road test to show that you can operate a commercial vehicle safely.
#8. Which of the following drivers are exempt from wearing seatbelts?
Drivers who get in and out of their vehicles frequently as part of their work may be exempt from wearing seatbelts while they’re driving at 40 km/h per hour or less. Exemptions include inner-city delivery drivers, bus drivers and emergency vehicle drivers.
#9. Which of the following statements are true about timber used as dunnage?
The tiedowns may have to withstand forces up to 0.8 g. Any timber used as dunnage, chocks or cradles for blocking or bracing must be strong enough that it will not be split or crushed by the cargo or the tiedowns. Note: In this context, “1 g” means the acceleration of one Earth gravity (9.8 metres/second²) – NOT one gram.
#10. If your cable tiedowns are not marked with their safe working load limits, what should you do?
According to National Safety Code Standard 10 (Cargo Securement), you may not use a tiedown or a component of a tiedown to secure cargo to a vehicle unless it is marked by the manufacturer with respect to its working load limit.
#11. To turn right safely, what should you do?
When turning any vehicle, you should always check your blind spots thoroughly. Also, the rear wheels of a vehicle with a long wheelbase can off-track (travel a different path than the front wheels). If you turn too sharply to the right, the rear wheels may scrape the curb or overrun the sidewalk. And if you turn too wide, pedestrians or vehicles may be encouraged to squeeze by you on the right. When turning, therefore, make certain that you’re not crowding any vehicles or pedestrians on the right side.
#12. If your vehicle is equipped with antilock brakes (ABS), how should you brake in an emergency?
If your vehicle has ABS brakes, don’t pump the brakes. Apply full, firm, steady pressure to the brake pedal. The ABS computer will automatically release and reapply a brake for you when it senses that wheel is about to lock up.
#13. During your pre-trip inspection, you discover a defect that does not affect the safe operation of the vehicle. What should you do?
You must note all defects on your inspection report. If the defect isn’t safety related, your report must say so. Then the defect can be repaired after your trip is over.
#14. When should you adjust an automatic slack adjuster?
Once properly installed, automatic slack adjusters shouldn’t need manual adjustment. If an automatic slack adjuster strokes beyond the maximum allowed, it usually indicates that there are other brake problems that need to be repaired by a qualified brake service mechanic.
#15. What is the purpose of the National Safety Code?
The National Safety Code (NSC) is designed to create a comprehensive code of minimum performance standards for the safe operation of passenger and commercial vehicles. The NSC focuses on three components: the driver, the vehicle, and the carrier. It has a specific focus on those responsible for the operation of commercial vehicles on the road, including trucks, buses, tractors, and trailers.

#16. When driving in the Yukon or Northwest Territories, you may drive no more than ____ hours during your on-duty time.
In the Yukon or Northwest Territories, you may have no more than 18 hours of on-duty time. You may drive no more than 15 hours during your on-duty time.
#17. How often should you inspect your vehicle?
All commercial vehicles that fall under the National Safety Code (NSC) must be inspected before they’re used each day (pre-trip inspections) and at the end of the final trip of each day (post-trip inspections). These inspections are required under the Motor Vehicle Act Regulations. Either you or another person specified by the carrier must perform these inspections.
#18. Under British Columbia law, what is the definition of a "special vehicle"?
Under British Columbia law, a “special vehicle” is defined as a motor vehicle that has a carrying capacity of no more than 10 persons (including the driver) and is designed or modified for public transportation of persons with disabilities.
#19. Where would an air dryer be installed in an air brake system?
An air dryer may be installed in the compressor discharge line between the compressor and the first reservoir. Its purpose is to remove water vapour and contaminants from compressor air before the air enters the first reservoir. The first reservoir has usually been the supply or “wet” reservoir, so called because moisture accumulated in that reservoir before the air flowed from there to the service reservoirs. However, today’s air dryer technology is so effective that a “wet” reservoir may not be needed anymore. In a modern Air Dryer Integrated System (ADIS), the air compressor governor and the air dryer are combined into a single unit. Air from the air dryer goes directly into the primary and secondary service (“dry”) reservoirs.
#20. Which of the following are normal responses from an antilock braking system (ABS)?
To perform emergency braking with ABS, just apply firm, hard, continuous pressure to the brake pedal until the vehicle stops. Don’t be concerned about brake noise, pedal movement or shudder. All this is normal with ABS. Keep applying firm pressure.
#21. What is a "glad hand"?
Because tractors and trailers need to be disconnected and reconnected from time to time, the air lines are equipped with quick coupling devices called glad hands. Each coupler resembles a human hand about to make a handshake.
#22. Which of the following may reduce the amount of steering control you have?
For best traction, tires should have adequate tread and be properly inflated. Overinflating a tire causes excess wear in the centre part of its tread. An overinflated tire has less tread surface in contact with the road surface. Less contact between your tire and the road means less traction. Underinflating a tire causes excess wear on the outer edges of its tread. Under wet conditions, an underinflated tire will not channel the water away very well, which may lead to hydroplaning.
#23. You're driving on a curve to the left. How can you ensure that your trailer's wheels stay in your lane?
When you curve to the right, keep the front wheels close to the centre line of the roadway to keep your rear wheels from drifting onto the shoulder or off the pavement. When curving to the left, keep the front wheels close to the right edge of your lane to keep your driver’s-side rear wheels from drifting into the lane to your left.
#24. How should you back up a tractor-trailer?
When backing a car, bus or straight truck, you first turn the steering wheel in the direction you want to go. But if you try that with a tractor-trailer, the trailer will pivot on the fifth wheel, and its rear will end up pointing in the wrong direction. When backing a tractor-trailer, you first turn the steering wheel in the direction that is opposite to where you want to go. The trailer will pivot, and its rear will end up pointing in the direction you want to go. Then turn the steering wheel the other way to follow the trailer, and continue backing.
#25. A tractor-trailer travelling at high speeds creates air turbulence in which of the following areas?
Large vehicles travelling at high speeds create air turbulence that can be hazardous to smaller vehicles. A tractor-trailer creates air turbulence directly in front of the truck, alongside the cab, by the rear area of the trailer, and at the immediate rear of the trailer.
