Class 4 Mock Test

#1. When you're driving an ambulance in response to an emergency call, you are allowed to do which of the following?

Send a text message from a hand-held cell phone

Exceed the speed limit

All of the above

Drive past a red traffic light without stopping

If you are transporting a patient or responding to an emergency call, you may exceed posted speed limits and drive through red traffic lights or past stop signs if you give other drivers the appropriate warning. (Use both the flashing red lights and the siren to warn other drivers.) You may disregard rules and traffic control devices governing direction of movement or turning in specified directions. You may also send email or text messages from a hand-held cell phone if you are doing so in the performance of your duties. [Sections 122 and 214.2, British Columbia Motor Vehicle Act]

#2. The time you spend riding on a ferry is considered off-duty time unless

You are a bus driver selling tickets while on the ferry.

The ferry ride is less than one hour.

You must take a ferry to get home from work.

Any of the above are true.

On-duty time doesn’t include time spent on a ferry, unless you’re working while you’re on it (for example, when a bus driver is selling tickets). Note, however, that if you are taking the ferry to travel to your employer where you’ll start driving, this will be considered on-duty time if (a) your employer asked you to make the trip and (b) you will not have taken eight consecutive hours of off-duty time immediately before you start your driving time.

#3. A taxi driver must test the brakes on the taxi

Monthly

Weekly

Daily

Every 48 Hours

A taxi driver must test the brakes on the taxi every day as part of the pre-trip inspection of the taxi. The driver must not operate the taxi unless the brakes are safe.

#4. If your brakes get wet, what should you do?

Pump the brakes.

Apply slight pressure to the brakes for a short distance.

Don't use the brakes for a short distance.

Brake hard whenever possible.

During extremely wet conditions, or after driving through water, test your brakes by applying slight pressure with your foot to the brake pedal. Keep this pressure on for a short distance. The resulting heat will dry out the brakes.

#5. If you are parking a vehicle on a downgrade, you should

Keep your wheels facing straight ahead.

Turn the wheels toward either the edge or the centre of the roadway.

Turn your wheels toward the edge of the roadway.

Turn your wheels toward the centre of the roadway.

If you’re parking any type of motor vehicle (even a passenger car) on a downgrade, turn your wheels toward the edge of the roadway. If your vehicle’s brakes fail, your vehicle will roll toward the edge of the roadway, not into traffic.

#6. Every commercial passenger vehicle with a seating capacity of more than 12 occupants (including the driver) must have which of the following?

(c) A light at each entrance

Both (a) and (c)

(b) Lights that illuminate the passenger aisle all the time

(a) Lights that illuminate the passenger aisle between sunset and sunrise

Every commercial passenger vehicle with a seating capacity of more than 12 occupants (including the driver) must have lights that illuminate the passenger aisle between sunset and sunrise, and a light at each entrance that turns on when the door is opened.

#7. Every motor vehicle must be equipped with at least ______ separate braking systems.

TWO

FOUR

THREE

ONE

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. While your vehicle is in motion, you should

Focus on driving.

Allow passengers to move around in the aisle.

Chat with passengers to make them feel welcome.

Use the time to make change for passengers.

You can best protect your passengers by making certain that the vehicle you use to transport them is safe and by operating it properly. While driving, focus on the driving task and avoid distractions such as interacting with passengers. However, keep an eye on your passengers. Make sure that they’re not changing their seats or standing up or moving around in the aisle while the vehicle is moving.

#9. What emergency equipment is required in a bus?

Warning flags, first-aid kit, and flashlight

Flares, first-aid kit, fire extinguisher, and flashlight

Gloves, first-aid kit, and fire extinguisher

Warning triangles, first-aid kit, and fire extinguisher

Every commercial vehicle must have at least two warning triangles (a school bus must have at least three). In addition, every bus (including every school bus) must have a first-aid kit and at least one fire extinguisher.

#10. What is total stopping distance?

Another name for the white bar on the road at a stop sign or traffic light

How long it takes to stop at a stop sign

How far your vehicle travels when you lightly press the brake pedal

How long it takes to stop after your eyes see a road hazard

Total stopping distance is the sum of your perception distance (how far the vehicle goes from when you see the hazard until your brain processes it), reaction distance (how far the vehicle goes from when your brain orders your foot to take action until your foot actually starts to brake), and braking distance (how far the vehicle continues to travel once you apply the brake). If your vehicle is equipped with air brakes, there is an additional lag of 0.4 seconds from the time you apply the brake pedal and the time that the brakes engage. The lag distance is the distance your vehicle travels during this lag, and it must be added to the total stopping distance.

#11. Peak torque is

Used to develop speed.

Found at a lower engine speed than peak horsepower.

Found at a higher engine speed than peak horsepower.

The level of torque at which you should be operating your vehicle.

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.

#12. If you reduce a tire’s air pressure when it is warm,

(a) you will reduce the chances of the tire bursting.

(c) you will reduce the amount of contact between that tire and the road surface.

(b) you may cause excessive flexing of the tire.

Both (a) and (c) are true.

When tires get warm, the air pressure increases. However, relieving that extra pressure may leave the air pressure too low when the tires cool again. Then the tires will tend to flex more, which can generate so much heat that the tires overheat. If your tires are too hot to touch, stop until they have cooled down.

#13. Why do the hours of service regulations exist?

Because tired drivers are more likely to get into accidents

So carriers can avoid paying their drivers overtime

So drivers can spend more time with their families

To keep driving time within union rules

Hours of service regulations are designed to limit the time you can spend driving. Statistics show that a fatigued driver is more likely to be in a crash. To help yourself get enough rest and stay alert, follow the hours of service regulations and get enough sleep every 24 hours.

#14. Before you enter a curve, what gear should you select?

A gear that lets you drive around the curve while using engine power throughout

A gear that lets you drive around the curve while also using the brakes

The same gear that you are already using

A gear that lets you drive around the curve without using either the brakes or engine power

Before you enter a curve, slow to a safe speed and downshift to a gear that lets you use engine power all through the curve. This will keep your vehicle stable and provide god acceleration as you leave the curve.

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

Above peak horsepower.

Below peak torque

Below peak horsepower.

Above 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.

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

(a) Take another route.

(c) Use your four-way flashers.

Do (b) and (c).

(b) Keep right.

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.

#17. To stop quickly in an emergency, what should you do if your vehicle has antilock brakes (ABS)?

Pump the brakes.

Apply firm, continuous pressure to the brake pedal.

Take your foot off the brakes once you feel the brake pedal pulsate.

Repeatedly brake until the wheels are about to lock, then release.

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

#18. To ensure smooth braking in any size vehicle, you should

Maintain a safe following distance.

Drive at a speed that allows you to see a safe distance ahead.

Do all of the above.

Brake early to spread out the braking load.

Try to avoid sudden “panic” stops. Drive at a speed that gives you adequate time to respond smoothly to hazards. Maintain an adequate following distance behind the vehicle ahead, and increase your following distance even more under poor driving conditions. 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.

#19. If you need to keep a daily log, what else do you need to keep with you?

All of the above

Pre-trip inspection report

Bills of lading

Shipping documents

Inspectors or police officers may ask to see your logbook. You must present your logbook and any supporting documents when asked. The documents may include bills of lading, shipping documents, and fuel receipts and accommodation receipts for expenses incurred along the route. Inspectors or police officers may also ask to see your pre-trip inspection report. You may be fined if you fail to have it with you.

#20. Travelling as a passenger to a place where you will start working as a driver counts as on-duty time if

Both (a) and (b) are true.

Either (a) or (b) is true.

(b) you won't have taken 8 consecutive hours of off-duty time immediately before you start your driving time.

(a) the company you work for has asked you to make the trip.

If you’re travelling to a place where you’ll start driving commercially, this will be considered on-duty time if (a) your employer asked you to make the trip and (b) you will not have taken eight consecutive hours of off-duty time immediately before you start your driving time.
