Class 4 Mock Test
#1. After you obtain a commercial driver’s licence, your driving record will
Every company you work for is required to check your driving record before hiring you and once a year after hiring you.
#2. Every commercial passenger vehicle with a seating capacity of more than 12 occupants (including the driver) must have which of the following?
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.
#3. An engine governor is
Large commercial vehicles are equipped with engine fuel governors. An engine governor (not to be confused with the air compressor governor in an air braking system) acts as an engine speed controller by regulating the amount of fuel going to the engine. A governor also lets you start a vehicle on level ground and on grades without using the throttle.
#4. Before you enter a curve, what gear should you select?
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.
#5. 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.)
#6. 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.
#7. Under British Columbia law, a special activity bus
Under British Columbia law, a “special activity bus” is defined as a bus that (a) conforms to the safety standards set out in the Canada Motor Vehicle Safety Act that applied to this vehicle when it was manufactured; (b) is operated by, on behalf of, or at the request of the authority in charge of a school; and (c) is used for non-scheduled transportation.
#8. Why is it risky to drive faster than the traffic flow?
If you drive faster than the traffic flow, you’ll increase your chances of crashing into vehicles in front of you, for a variety of reasons: 1. You may not be able to maintain a safe following distance. 2. You’ll increase your chances of making a wrong decision. 3. You may tire more quickly. Driving faster than the traffic flow creates tension and causes mental and physical fatigue.
#9. While you're driving a school bus, it breaks down on the road. What should you do?
If your school bus breaks down on the road, try to stop the bus in a safe place as far off the roadway as practical. If it’s daylight, place warning triangles 30 metres in front of and behind the bus. In darkness or under other conditions of low visibility, place warning triangles 75 metres in front of and behind the bus. Whether you should evacuate the passengers from the bus depends on whether conditions are safer inside or outside the bus.
#10. Before you may apply for a commercial driver’s licence, you must already hold which class of driver's licence?
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.
#11. A tire that is overinflated or underinflated can
Underinflating a tire causes excess wear on the outer edges of its tread. Underinflation also causes increased flexing of the tire, which increases the chance of a blowout or even a fire from excessive heat buildup. Overinflating a tire causes excess wear in the centre part of its tread. Overinflation makes the tire more susceptible to damage from potholes or other road irregularities and increases the chance of tread separation and tire failure.
#12. What colour are the flashing lights used by an ambulance driver to warn others to yield?
When operating an ambulance, use flashing red lights to warn other drivers when it is essential that you get the right-of-way. These lights are to be used only when you are responding to an emergency call or transporting a patient.
#13. If you must drive more slowly than the traffic flow, you should
Slower-moving vehicles should keep right and allow faster vehicles to pass on the left.
#14. At an intersection with no traffic lights or traffic signs, you should
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
#15. What is the purpose of an antilock braking system (ABS)?
ABS does not have much effect on your everyday driving. It does not affect your braking capability or shorten your stopping distance. It just helps you keep control of your vehicle by activating when your wheels are about to lock
#16. 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 brakes 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
#17. If your passenger vehicle breaks down and you cannot continue the trip, what should you do?
If your vehicle develops a problem that could endanger any passengers’ safety or comfort or prevent you from transporting them to their destination, fix the problem before continuing the trip. If this proves impossible, make immediate arrangements to have the passengers transported to their destination with as little delay as possible.
#18. When driving at night, you should do which of the following?
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
#19. Under British Columbia law, what is the definition of "public transportation"?
Under British Columbia law, “public transportation” is defined as the transportation of groups of people who aren’t your associates or members of your family.
#20. Which of the following can increase the length of your danger zone (as defined in the British Columbia Driving Commercial Vehicles Manual)?
The section of road that your vehicle travels through before it can stop is called the vehicle’s danger zone, because it’s physically impossible for you to stop the vehicle in time to avoid a collision with any object or person. As your speed increases, the length of your danger zone increases. Less than ideal road conditions, such as rain, snow, ice or gravel increase the length of your danger zone. Driving fast under these road conditions increases your danger zone even more. Finally, heavy commercial vehicles have more kinetic energy than cars travelling at the same speed and therefore take longer to brake to a stop.
