Class 1 Mock
#1. 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.
#2. 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.
#3. What can cause a trailer to swerve or whip across the roadway?
Swerving or whipping of a trailer can be caused by a shifting load, improper trailer connections, sudden steering changes, or driving too fast for the conditions. It can also be caused by mechanical problems, such as dragging brakes or a flat tire
#4. 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.
#5. 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.
#6. 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.
#7. 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
#8. 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.
#9. If a fire starts in your vehicle, you should do which of the following?
If a fire starts in your trailer, don’t open the trailer doors; the additional oxygen will make the fire worse. Likewise, if a fire starts under the hood, don’t open it. Putting water on gasoline, grease or oil fires will only spread the fire farther. Instead, use a fire extinguisher that is rated for Class B (flammable liquid) fires. Use enough extinguishing material to put out the flames, but try to keep some in reserve in case the fire flares up again.
#10. 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.
#11. 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.
#12. Drivers on Cycle 1 must not drive after completing ____ hours of on-duty time in seven consecutive days.
#13. 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.
#14. 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.
#15. Different-sized tires can
Using tires of different sizes or different types (e.g., radial and bias ply) on the same axle can adversely affect handling, especially when braking.
#16. 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.
#17. Who has the right-of-way on a steep hill on an industrial road?
Industrial roads are often rougher and present different types of conditions than public roads. In general, drivers are expected to follow the rules of the road set out in the Motor Vehicle Act. However, you should yield the right-of-way to a loaded truck that is coming down a steep hill on an industrial road
#18. Why must you prevent tiedowns from rubbing against your load?
Tiedowns can become abraded or frayed by rubbing against the cargo. Eventually the tiedown may tear open. To prevent this, use dunnage to separate the cargo from its tiedown
#19. Peak torque is
According to the British Columbia Driving Commercial Vehicles Manual, torque is the ability of the engine to move the vehicle, and horsepower is used to develop speed. 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.
#20. 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.
#21. 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.
#22. 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.
#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. 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.
#25. 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.
