Class 1 Mock
#1. 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.
#2. 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.
#3. 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.
#4. When a tractor-trailer is loaded, the cargo should be
Keep your cargo as close to the centre of your rig as possible so it won’t cause your trailer to lean to one side or the other. It’s also critical to spread out your cargo and keep it as close to the trailer deck as possible. As the height of a load increases, its centre of gravity rises (i.e., the load becomes top-heavy). A vehicle with a higher centre of gravity is more likely to roll over.
#5. A tire that is overinflated or underinflated can
Underinflating a tire causes excess wear on the outer edges of its tread. Underinflation also increases the chance of a blowout or even a fire from excessive heat buildup resulting from increased flexing of the tire. Overinflating a tire causes excess wear in the centre part of its tread. Overinflation makes the tire more susceptible to damage from potholes or other road irregularities and increases the chance of tread separation and tire failure.
#6. When can flashing amber lights be mounted on a vehicle?
Flashing amber lights are used on construction vehicles, towing vehicles, tow cars that are attending, snow-removal equipment, sanding equipment, pilot cars, and vehicles that are required by permit to use them, such as some oversize vehicles or vehicles carrying oversize loads. If your vehicle is going to haul an oversize load, obtain a Commercial Vehicle Safety & Enforcement permit from ICBC. This will allow you to mount flashing amber or red lights on your vehicle as well as the appropriate oversize signs.
#7. Every motor vehicle must be equipped with at least ______ separate braking systems.
Every motor vehicle must be equipped with at least two separate braking systems. One braking system must be mechanical, such as a ratchet and pawl (notched wheel) mechanism or a spring brake mechanism. The mechanical system should be used as a backup in case the primary braking system fails.
#8. f you are carrying a six-metre load weighing 8,000 kg, and each tiedown has a safe working load limit of 3,000 kg, how many tiedowns should you use?
As a rough guide, use two tiedowns for the first 3.04 metres of a load and one tiedown for every 3.04 metres after that. So for a six-metre load, use three tiedowns. In this case, the load weighs 8,000 kg, and each of the three tiedowns has a safe working load limit of 3,000 kg, which is more than adequate for the weight of this load.
#9. What is brake lag time?
When you press the brake pedal, some type of force must be transmitted to the brakes to make them work. Hydraulic brake systems use brake fluid. Because brake fluid cannot be readily compressed, force is transmitted immediately to each brake when you press the brake pedal. Air brake systems use compressed air to produce the force that applies the brakes at each wheel. When you press the brake pedal, compressed air must flow from one part of the system to another. Unlike brake fluid, air is compressible, resulting in a delay of up to 0.4 seconds from the moment you apply or release the brake pedal to the moment that the brakes respond accordingly.
#10. 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.
#11. 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.
#12. Under hours of service regulations, a sleeper berth can be
Under hours of service regulations, neither a reclining seat nor the rear seat of a bus qualifies as a sleeper berth.
#13. When you couple your tractor to a trailer, which of the following is most important?
Don’t drive the vehicle until you’re sure that the coupling is correct. Inspect the coupling thoroughly. If the coupling seems loose in any way, make the necessary adjustments before you drive.
#14. Without an oversize load permit, the tallest your vehicle can be is
The maximum allowable height for a commercial vehicle is 4.15 metres unless the driver has an oversize load permit.
#15. 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.
#16. 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.
#17. Over-braking with a trailer can sometimes lead to
Over-braking the rear drive wheels can cause them to lock. Because locked wheels have less traction than rolling wheels, the rear wheels usually slide sideways in an attempt to “catch up” with the front wheels. With vehicles towing trailers, a drive-wheel skid can let the trailer push the towing vehicle sideways, causing a sudden jackknife.
#18. To stop quickly in an emergency, what should you do if your vehicle has antilock brakes (ABS)?
If you must stop in an emergency, apply firm, hard continuous pressure to the brake pedal until you come to a complete stop. Don’t worry about possibly locking the wheels. If the ABS computer senses that a wheel is about to lock, it will automatically release that brake to get the wheel rolling again, then reapply the brake. When ABS is working, some pulsation of the brake pedal is normal.
#19. What is the purpose of an antilock braking system (ABS)?
ABS does not have much effect on your everyday driving. It does not affect your braking capability or shorten your stopping distance. It just helps you keep control of your vehicle by activating when your wheels are about to lock.
#20. If you are parking a single-unit (straight) vehicle on an upgrade without a curb, you should
The rule for single-unit (straight) vehicles (such as buses, three-axle trucks, and “bobtail” tractors without trailers) on upgrades is the same as for cars: If there is a curb, turn your wheels away from the curb (i.e., toward the centre of the road). If your vehicle’s brakes fail, the curb will block your vehicle from rolling backward. If there is no curb, turn your wheels toward the edge of the road. If your vehicle’s brakes fail, your vehicle will roll off the road, not into traffic.
#21. Where is a single-unit (straight) truck’s central weight distribution point?
The central weight distribution point of the average single-unit (straight) truck is located partially over or just ahead of the rear axles. That is where the load should be placed.
#22. When parking a vehicle with a two-speed axle, in which range should you leave the axle?
If your vehicle is so equipped, a two-speed drive axle allows you to select a lower gearing for greater torque at lower speeds. When you park your vehicle, you want maximum torque from both the transmission and the two-speed drive axle to prevent your vehicle from rolling, should its brakes fail. Place the transmission in the lowest forward gear, if parked facing uphill, or reverse gear (which is also a low gear) if parked facing downhill, or park if the vehicle has an automatic transmission. If the vehicle has main and auxiliary transmissions, place both in gear. If the vehicle is equipped with a two-speed axle, the axle should be in low range.
#23. Why are hours of service regulations in place?
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.
#24. Why is turning right in a tractor-trailer dangerous?
Because of off-tracking, you risk crowding someone, such as a cyclist, who’s travelling on your right side. Running your rear wheels over curbs and sidewalks can damage your tires and seriously injure pedestrians and cyclists. Unfortunately, at the point where the tractor has made the turn but the trailer hasn’t, the right rear-view mirror is turned so you can’t view road users with it. And if you try to swing wide to avoid overrunning the curb, other drivers may be tempted to squeeze by you on your right side, which can lead to a collision.
#25. 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.
