Class 1 Mock
#1. At which of the following engine speeds should you drive your vehicle?
At any given speed, the engine develops both torque and horsepower. Peak torque is found at a lower engine speed than peak horsepower. The vehicle should be operated between the engine’s peak torque and peak horsepower. This range is referred to as the normal operating rpm range of the engine. The engine will lug (strain) if it is operated below peak torque for any length of time
#2. 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.
#3. During a pre-hill inspection of a vehicle equipped with hydraulic brakes, you should do which of the following?
Whether your vehicle has air brakes or hydraulic brakes, it is important to make sure that the brake drums haven’t overheated. To test hydraulic brakes for leaks, first pump the brakes three times. Next, apply firm pressure to the brake pedal for five seconds. The pedal should not move. If it moves, the brakes may have a leak or some other problem.
#4. To travel down a steep hill, what should you do?
If you keep applying the service brakes to control your speed on a steep downgrade, the brakes may fade (become less effective). Instead, shift into a lower gear to slow your vehicle. Use a gear that is lower than the gear you would use to go up that hill. Also use your retarder unless you’re on a slippery road (which could increase the chance of a skid). Don’t try to downshift after your speed has already built up. You may not be able to shift into a lower gear at that point.
#5. 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.
#6. Stopping on icy roads requires
When driving on ice, sleet or snow, drive slowly and increase your following distance so you can manoeuvre gradually. Apply light pressure to your brake pedal. Avoid turning the steering wheel in a quick or erratic manner.
#7. 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.
#8. 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.
#9. 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
#10. 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.
#11. 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.
#12. After working 120 hours in a 14-day cycle, drivers must take ____ consecutive hours of off-duty time before taking 70 hours of on-duty time.
Drivers working on Cycle 2 must not drive after completing 120 hours in 14 days, and they must take at least 24 consecutive hours off duty before accumulating the next 70 hours of on-duty time.
#13. 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.
#14. 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.
#15. The working load limit of tiedowns used to secure cargo must be at least _____ of the cargo weight.
The working load limit of tiedowns used to secure cargo must be at least 50 percent of the cargo weight.
#16. 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.
#17. 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.
#18. 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.
#19. What does an ABS system do?
#20. If a peace officer asks for your logbook and supporting documents, what documents should you provide?
Supporting documents may include bills of lading, shipping documents, fuel receipts, and accommodation receipts for expenses incurred along the route. (A bill of lading is issued by a carrier to acknowledge receipt of cargo for shipment by the carrier.)
#21. 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.
#22. 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.
#23. 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.
#24. When should you perform a pre-hill inspection?
British Columbia has many mountainous roads. You must perform a brake pre-hill inspection (brake check) wherever a sign is posted requiring you to do so before a steep hill ahead. (You may be fined for failing to stop to conduct a brake pre-hill inspection.) It’s also wise to perform a pre-hill inspection before every long or steep downgrade
#25. 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.
