Class 4 Mock Test

#1. How should you upshift a gasoline-powered vehicle that is not equipped with a governor?

Shift into higher gears as soon as you have the power to do so.

Do all of the above.

Engage the clutch smoothly and engage the throttle at the same time.

Use only enough throttle to start the vehicle moving.

Smaller commercial vehicles usually don’t have governors to regulate engine rpm and the amount of fuel burned. To upshift a gasoline-powered vehicle that is not equipped with a governor, perform the following steps: 1. Start in low gear. Use only enough throttle to start the vehicle moving. 2. When the engine begins to accelerate, quickly shift into the next gear. Shift into higher gears as soon as you have the power. 3. As your vehicle’s speed increases and you begin shifting into the higher gears, allow the engine to develop more power before each shift so the rate of acceleration increases. 4. As you complete each shift, engage the clutch smoothly, and engage the throttle at the same time.

#2. Stopping on icy roads requires

shifting into a lower gear.

light pressure on the brakes.

pumping the brakes.

heavy brake use.

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.

#3. Your vehicle's engine will start to lug (strain) if it is operated

Above peak torque.

Above peak horsepower.

Below peak horsepower.

Below peak torque

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 if it is operated below peak torque for any length of time.

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

It's more comfortable.

It can reduce the risk of injury in a rear-end crash.

It's required by law.

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.

#5. To drive defensively, you should

Do all of the above.

Watch the traffic well ahead of your vehicle.

Prepare to stop as you approach a stale green light.

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

#6. Drivers on Cycle 1 must not drive after completing ____ hours of on-duty time in seven consecutive days.

40

50

60

70

Drivers on Cycle 1 (a seven-day cycle) must not drive after completing 70 on-duty hours in seven consecutive days.

#7. Which of the following are true about brake fade?

Recovery is possible if brake fade hasn't gone on too long.

All of the above are true.

Your vehicle will take longer to stop.

Your brakes may stop working altogether.

Excessive or prolonged braking can cause the brakes to overheat. This can lead to a loss of braking effectiveness, known as brake fade. Your vehicle may take longer to stop. If the brakes continue fading, they may stop working altogether. If you pull over and stop using the brakes, they may recover after they cool down. However, brake fade that continues for a long period can cause changes to the brake linings that will require service.

#8. How often should you look at your mirrors?

About every 5 to 8 seconds

Only when there are vehicles behind you

Only when backing up

About every 10 to 12 seconds

While you’re driving, keep your eyes moving. Scan the road well ahead. Then scan the road from one side of the road to the other. Then check your mirrors. Keep repeating this cycle every 5 to 8 seconds.

#9. At an intersection with no traffic lights or traffic signs, you should

Slow down and be ready to brake as you pass through.

Keep up your speed and look for oncoming vehicles.

Honk your horn to signal your position to other drivers.

Treat this intersection as a four-way stop.

Uncontrolled intersections have no signs or traffic lights. As you approach an uncontrolled intersection, slow down and look out for other road users. Follow the rules of the road to decide when to yield the right-of-way. To yield, slow down and stop if necessary

#10. Why must you prevent tiedowns from rubbing against your load?

So that the tiedowns will look good for your employer at the end of your trip

So that the tiedowns won't make distracting noises

So that the load won't be damaged

So that the tiedowns won't be damaged

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 tiedowns.

#11. Which of the following is not a Class 4 vehicle?

A taxi

An ambulance

A 30-passenger school bus

A 16-passenger minibus

Class 4 motor vehicles include ambulances, taxis, and buses with a seating capacity of 24 passengers or less.

#12. You're driving an ambulance in response to an emergency call. Whenever you exceed the speed limit or drive through stop signals, you must consider which of the following?

The condition and use of the roadway

All of the above

The amount of traffic that is on, or expected to be on, the roadway

The seriousness of the emergency to which you are responding

If you are transporting a patient or responding to an emergency call, you may drive faster than posted speed limits and drive through red traffic lights or past stop signs if you warn other drivers with your vehicle’s siren and flashing red lights. Before taking such risky actions, however, consider such factors as (a) the condition and use of the roadway; (b) the amount of traffic that’s on, or is expected to be on, the roadway; and (c) the seriousness of the emergency to which you’re responding

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

Either Class 5 or Class 6

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.

#14. Which vehicles are required to stop at uncontrolled main railway crossings?

Buses carrying passengers

Vehicles carrying flammable liquids

Vehicles carrying explosives

All of the above

The following vehicles are required to stop at all uncontrolled main railway crossings: (a) buses carrying passengers, including school buses carrying children; (b) vehicles transporting explosive, poisonous or flammable substances as cargo or as part of their cargo; and (c) vehicles used to transport combustibles, corrosive liquids, or liquefied petroleum gas, whether empty or loaded.

#15. When you see a potential hazard in your danger zone, you should

Wait and see if it becomes an emergency.

Speed up and try to swerve around it.

Come to a complete stop until the hazard is gone.

Cover the brake pedal.

A hazard is a road user or road condition (such as a busy intersection) that presents a possible danger. A hazard is not an emergency – but it can quickly become one. When you spot a hazard, prepare to deal with any emergency that might develop. For example, cover the brake pedal with your foot to shorten your reaction time. Keep your eye on that hazard and be ready to act instantly if necessary.

#16. Which of the following statements about revolutions per minute (rpm) are true?

It helps you decide when to shift.

All of the above are true.

It's the number of turns the crankshaft makes in one minute.

It's displayed on your tachometer.

Revolutions per minute (rpm) is a measure of rotational speed. For an internal-combustion engine, rpm is the number of turns the crankshaft makes in one minute. The tachometer on your instrument panel shows the current crankshaft rpm. You should upshift before engine rpm becomes excessive.

#17. When driving at night, you should do which of the following?

Travel at the posted speed limit.

Flash your headlights at approaching drivers who forget to switch from high beam to low beam.

Make sure you can stop within the distance you can see.

On well-lit roads, you can use your parking lights instead of your headlights.

In the dark, you have no way of knowing what lies beyond the reach of your headlights. At night, you should slow to a speed that allows you to stop safely within the range of your headlights. Otherwise, if there is a hazard just beyond the range of your headlights, you may not be able to take action in time to avoid it. Your parking lights are for parking, not d

#18. You can be charged under the Criminal Code of Canada or the British Columbia Motor Vehicle Act if

You refuse a test for alcohol upon the request of an officer.

You are found to be driving with a blood alcohol content between 0.05% and 0.08%.

You are found to be driving with a blood alcohol content of over 0.08%.

Any of the above is true.

The national blood alcohol limit is 0.08%. If you are found driving with a blood alcohol content of 0.08% or above, you can be charged under the Criminal Code. However, British Columbia has established a more stringent standard. In British Columbia, if you are found driving with a blood alcohol content of over 0.05%, you can be charged under the British Columbia Motor Vehicle Act. Under both the Criminal Code and the Motor Vehicle Act, you can also be charged for refusing a test for alcohol upon the request of an officer. Penalties for violating national or provincial laws can be severe, including loss of licence, vehicle impoundment, fines, and even jail.

#19. According to the British Columbia Driving Commercial Vehicles Manual, torque is

The ability of the engine to move the vehicle.

Used to develop speed.

The same as rpm.

The same as horsepower.

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. More specifically, in an internal-combustion engine, torque is the rotational force that is produced by the engine’s crankshaft.
