Class 1 Mock
#1. To back up with the aid of a guide, what should you do?
Before backing, you and your guide should agree on some convenient hand signals that the guide can use to direct you – especially a hand signal for “Stop.” Position the guide where there’s a clear, continuous view of the backing path that your vehicle will follow. Make sure you can see the guide throughout the manoeuvre.
#2. Drivers on Cycle 2 must not drive after completing ____ hours of on-duty time in 14 consecutive days.
Drivers on Cycle 2 (a 14-day cycle) must not drive after completing 120 on-duty hours in 14 consecutive days. Furthermore, they must take at least 24 consecutive hours off duty prior to accumulating 70 hours of on-duty time.
#3. Which of the following can increase the length of your danger zone (as defined in the British Columbia Driving Commercial Vehicles Manual)?
The section of road that your vehicle travels through before it can stop is called the vehicle’s danger zone, because it’s physically impossible for you to stop the vehicle in time to avoid a collision with any object or person. As your speed increases, the length of your danger zone increases. Less than ideal road conditions, such as rain, snow, ice or gravel increase the length of your danger zone. Driving fast under these road conditions increases your danger zone even more. Finally, heavy commercial vehicles have more kinetic energy than cars travelling at the same speed and therefore take longer to brake to a stop
#4. In large commercial vehicles, most air brake systems use automatic valves to
Most modern tractors are equipped with an automatic front axle ratio valve, which supersedes the manual front brake limiting valve in older tractors. In light-to-moderate braking, the ratio valve automatically reduces air pressure (and hence braking force) to the front wheels to reduce the chance of front-wheel lockup (which could result in a skid) on slippery roads.
#5. 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.
#6. What is the licensed gross vehicle weight (GVW)?
Several different terms are used to define a vehicle’s weight. GVW (gross vehicle weight) is the combined weight of the vehicle and its load. GVWR (gross vehicle weight rating) is a manufacturer’s rating that defines the weight of a vehicle and the maximum load that it should carry. Licensed GVW is the combined weight of the vehicle and the maximum load that it is licensed to carry or tow.
#7. 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.
#8. Idling for longer than five minutes can
Idling can burn up to four litres of fuel per hour. Idling for longer than five minutes wastes fuel, increases emissions, and can clog fuel injectors.
#9. 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.
#10. Why is it important to know which parts of the air brake system exhaust air?
Compressed air may be exhausted from several different ports in the braking system. This air travels at a very high speed from the vehicle and carries moisture, oil, dirt and dust. It can be dangerous if it hits your eyes or ears. Know the location of all air exhaust ports so you can keep away from them, such as when you’re draining the air tanks.
#11. What is the purpose of the slider on a trailer?
On many trailers, the driver can slide the tandem axles forward and backward to adjust the weight distribution of the trailer. Sliding the tandems forward puts more weight on the tandems and less on the tractor’s rear axles. Sliding the tandems backward puts more weight on the tractor’s rear axles and less on the tandems.
#12. What is a commercial vehicle’s danger zone?
The section of road a vehicle travels through before it can stop is called the vehicle’s danger zone because it’s physically impossible for you to stop in time to avoid a collision with any object or person. Reduce your danger zone by slowing down and covering the brake pedal with your foot if you spot a hazard.
#13. Under British Columbia law, what is the definition of a “taxi”?
Under British Columbia law, a “taxi” or “limousine” is defined as a motor vehicle that is designed to carry no more than 10 persons, and is available with its driver for hire. This includes a vehicle being used as part of a ride-hail service.
#14. 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.
#15. The supply line is also called
The supply air line is also called the emergency line. In the event that it breaks, the trailer air supply valve and the tractor protection valve will close automatically to prevent more air from leaving the tractor
#16. If you place a very heavy load on one side of a vehicle, what may happen?
If you place a very heavy load on one side of a vehicle, the brakes may lock the wheels on the underloaded side, which might cause the tires to skid on wet surfaces. It may also cause flat spots on the tires. Furthermore, the vehicle’s centre of gravity (i.e., the midpoint of its weight) will shift toward the side with the load, increasing the risk of a rollover
#17. After you __________, you must take at least eight consecutive hours of off-duty time.
Hours of service regulations are designed to limit the time you can spend driving. Statistics show that a fatigued driver is more likely to become involved in a crash. After driving for 13 hours or being on duty for 14 hours, you may not drive again until you have taken 10 hours of off-duty time, of which eight hours must be consecutive.
#18. When approaching a narrow bridge from a curve, you should
When entering a narrow bridge with a curved approach, proceed with caution and awareness of the amount of off-tracking your vehicle displays. Adjust your speed and position on the roadway appropriately.
#19. If you are unable to keep up with traffic on a steep grade, what should you do?
If you must drive slower than other traffic, use your four-way flashers to alert other drivers, and keep right to let the drivers pass you safely.
#20. 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.

#21. How should you handle driving around a curve?
To handle a curve, slow down before you enter the curve so that you will not need to brake in the curve. Braking in a curve can cause a skid. On slippery roads, slow down even more. Once you are in the curve, accelerate slightly through the curve. This will help you keep control.
#22. In determining how well your air brake system works, which is NOT a significant factor?
The faster you drive or the greater your vehicle’s weight, the longer your braking distance will be. A fully loaded tractor-trailer can weigh over 36 metric tons. The weight of a 180-pound man is only a fraction of one percent of that, so the effect should be insignificant.
#23. Load binders are used for what purpose?
A load binder is used to tighten a tiedown chain. Some load binders are tightened with a lever; others use a ratchet mechanism.
#24. What is the purpose of checking your vehicle’s slack adjusters?
It’s critical that you inspect your brakes as part of the pre-trip inspection. Brakes that are out of adjustment may fail to stop your vehicle safely, possibly resulting in a dangerous collision. Federal and provincial laws require you to check manual and automatic slack adjusters daily, during the pre-trip inspection. You may be fined as much as $2,000 for driving a vehicle with defective brakes. This includes excessive brake chamber pushrod stroke
#25. How can you ensure smooth braking of a large commercial vehicle?
Try to avoid sudden “panic” stops. Drive at a speed that gives you adequate time to respond smoothly to hazards. Maintain a following distance of at least five seconds behind the vehicle ahead. To brake, press the brake pedal gradually yet firmly. Just before your vehicle comes to a full stop, reduce the pressure you’re placing on the brake pedal. This will prevent your vehicle from jerking back, enabling you to make a smooth stop.
