Class 1 Mock

#1. The working load limit of tiedowns used to secure cargo must be at least _____ of the cargo weight.

100%

25%

50%

75%

The working load limit of tiedowns used to secure cargo must be at least 50 percent of the cargo weight.

#2. Load binders are used for what purpose?

To tighten tiedown chains

To contain aggregate loads

To hold down a load that is too large for the vehicle

To bind bundles of cargo such as logs or poles

A load binder is used to tighten a tiedown chain. Some load binders are tightened with a lever; others use a ratchet mechanism.

#3. Which of the following types of commercial vehicles are required to carry fire extinguishers?

All of the above

Public passenger vehicles

Vehicles transporting explosives

School buses

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.

#4. Before you may apply for a commercial driver’s licence, you must already hold which class of driver's licence?

Class 5

Either Class 5 or Class 6

Either Class 5 or Class 7

Class 6

To qualify for a commercial driver’s licence in British Columbia, you must have a rather clean driving record: fewer than four offences that carry penalty points in the last two years; no motor-vehicle-related Criminal Code convictions in the past three years; and no outstanding fines or debts owed to the Court, the Government or ICBC. Also, you must already hold a full-privilege driver’s licence from British Columbia or another province. Either a Class 5 car licence or a Class 6 motorcycle licence (or the equivalent from another province) is acceptable.

#5. At which of the following engine speeds should you drive your vehicle?

at Peak horsepower

Between peak torque and peak horsepower

below Peak torque

above peak Horsepower

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

#6. Why should you adjust your head restraint so its top is at least level with the top of your head?

It's required by law.

It helps prevent whiplash.

It's more comfortable.

It helps make driving more relaxing.

Head restraints (also called headrests) can help prevent soft-tissue injuries such as whiplash. Whiplash is an injury of the neck, head or shoulders after being subjected to a snapping motion. If your head restraint is adjustable (not part of the seatback), adjust it so the top is at least level with the top of your head. Also position your head restraint as close to the back of your head as possible. It may be necessary to adjust your seatback position to do this.

#7. If your cable tiedowns are not marked with their safe working load limits, what should you do?

Assume they have a strength equal to the lowest grade or classification of their type and size.

Don't use them.

Assume they have a strength equal to the highest grade or classification of their type and size.

Refer to NSC Standard 10 for the default working load limits.

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.

#8. Which of the following can increase the danger of crossing railway tracks?

The crossing surface is rough.

All of the above can increase the danger.

There is more than one track to cross.

Your vehicle is extremely heavy or long.

Railway crossings can be hazardous. You want to minimize the time you spend there. Still, it takes a typical tractor-trailer more than 10 seconds to clear a single railway track. And it can take even longer if the crossing surface is rough, there is more than one track to cross, your vehicle is extremely heavy or long, or the approach grades to the tracks are steep (which can cause a low-slung vehicle to get hung up on the tracks altogether).

#9. If your vehicle becomes disabled, what should you do?

Place warning devices farther than 30 metres from your vehicle.

Do all of the above.

Move it as far off the roadway as possible.

Place warning devices approximately 30 metres ahead of and 30 metres behind the vehicle.

If your vehicle becomes disabled, move it as far off the travelled portion of the highway as possible. Under the British Columbia Motor Vehicle Act, you must place warning devices approximately 30 metres ahead of and 30 metres behind the vehicle. However, it’s good safety practice to also place additional warning devices farther than 30 metres from your vehicle.

#10. Drivers on Cycle 2 must not drive after completing ____ hours of on-duty time in 14 consecutive days.

50

80

120

150

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.

#11. To drive defensively, you should

Prepare to stop as you approach a stale green light.

Do all of the above.

Be alert for vehicles that are about to pass you.

Scan the traffic all around you regularly.

Defensive driving is about anticipating potentially dangerous situations in advance, including driving conditions and mistakes made by others, and planning how to deal with those situations. To drive defensively, constantly scan the traffic ahead, behind and to your sides. Look ahead for clues that will tell you whether other vehicles are about to change speed or stop. For example, a green light that is stale may change to red at any moment, so be prepared to stop. Frequent checks of your rear- and side-view mirrors will alert you to drivers who are passing you or getting ready to pass you.

#12. What can cause a trailer to swerve or whip across the roadway?

All of the Above

Driving too fast for the conditions

improper trailer connection

shifting of the load

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

#13. Just before your vehicle comes to a full stop, you should __________ to prevent your vehicle from jerking back.

Brake hard one more time.

Pump the brakes.

Reduce pressure on the brake pedal.

Shift into a lower gear.

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. Practice stopping until you’ve learned how much pressure you need to ease off the brake to smoothly stop where you want.

#14. Over-braking with a trailer can sometimes lead to

Turbulence.

Slowing down.

None of the above.

Jackknifing.

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.

#15. What is the purpose of the National Safety Code?

To define minimum safety standards for car manufacturers

To specify how many hours a commercial driver can safely drive

To specify rules of the road for the safe operation of all kinds of vehicles

To specify minimum safety standards for commercial vehicles, drivers, and carriers

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. Which of the following is true about B-train couplings?

B-train couplings are illegal in Canada.

B-train coupling is safer than coupling to a tractor.

The second trailer connects directly to a converter dolly.

The second trailer connects directly to the lead trailer.

In a B train, the converter is part of the lead trailer. The fifth wheel assembly sits on the rear axle of the lead trailer. No converter dolly is required because the second unit connects directly to the extended frame of the lead unit.

#17. To inspect an air brake system, you should wear

shorts and sandals.

a dust mask and safety glasses.

a hard hat, safety glasses, and steel toe boots.

a leather jacket and work pants.

The compressed air that is used in air brake systems can be hazardous if you get near it when it is being exhausted from the vehicle. Compressed air leaving the vehicle travels at a very high speed and carries moisture, oil, dirt and dust. Plus there is always the chance of an accident in procedures that require you to release the brakes and crawl underneath your vehicle to inspect various items. While you’re inspecting the air brakes, wear a bump cap or hard hat, safety glasses, a visible safety vest, and steel toe boots.

#18. Under the British Columbia Motor Vehicle Act Regulations, how often must commercial vehicles be inspected?

Either A or B

Both A & B

A- Before they are use each day

B- at the end of the final trip of each day

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 do these inspections.

#19. If you are unable to keep up with traffic on a steep grade, what should you do?

(c) Use your four-way flashers.

(b) Keep right.

(a) Take another route.

Do (b) and (c).

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. Why is it important to know which parts of the air brake system exhaust air?

Because you may need to make repairs

In case anyone ever asks

So you won't be surprised

Because it can be dangerous

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.

#21. Drivers must hold an industrial air brake endorsement if they will be __________ on industrial roads.

driving licensed vehicle equipped with air break to transport natural resources

driving unlicensed vehicle equipped with air break to transport natural resources

driving loaders and graders equipped with air breaks

Transporting natural resources

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.

#22. If a trailer is not equipped with spring brakes and the trailer air brake system leaks, what will happen?

Both (a) and (c)

(b) The trailer brakes will be set (locked).

(c) The trailer may roll away.

(a) The trailer brakes will release.

After you’ve parked a trailer equipped with air brakes, some air will slowly leak from the trailer air brake system over time. Eventually, so much compressed air will be lost that the trailer brakes will release. If the trailer doesn’t have spring brakes as a backup, it may roll away unless you chocked (blocked) the wheels beforehand.

#23. What does an ABS system do?

Increases braking power.

brakes automatically when needed

shortens stopping distance

Prevent wheel locks

#24. Where are a large vehicle's blind spots?

Only in front of the vehicle

Behind, in front of, and to both sides of the vehicle

Only to the passenger side of the vehicle

Only to both sides of the vehicle

A large vehicle’s blind spots exist to the front, rear, and both sides of the vehicle. If a nearby bicycle or vehicle seems to suddenly disappear, it may have moved into one of your blind spots. Use caution.

#25. Which of the following statements are true about timber used as dunnage?

(c) It must be strong enough not to be split or crushed by the cargo.

(b) It must be protected with extra tiedowns.

(b) and (c) are true.

(a) It must be checked every 100 kilometres.

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.
