Class 4 Mock Test
#1. A taxi driver must test the brakes on the taxi
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.
#2. According to the British Columbia Driving Commercial Vehicles Manual, which dashboard gauge can help you decide when to upshift?
Learn the normal operating rpm range for your vehicle. The tachometer displays the current engine speed in rpm. According to the British Columbia Driving Commercial Vehicles Manual, you should upshift before your engine reaches the top of its normal rpm range.
#3. 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.
#4. 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.
#5. Why should you adjust your head restraint so its top is at least level with the top of your head?
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.
#6. Which vehicles are required to stop at uncontrolled main railway crossings?
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.
#7. Which of the following statements about a vehicle’s turning radius are true?
The turning radius of a vehicle is the radius of the smallest (tightest) circular path that the vehicle can traverse. A vehicle’s rear tires have a different turning radius than its front tires. You need to know the turning radius of your front wheels to prevent your vehicle’s rear wheels from overrunning the curb or corner when you turn. And knowing your vehicle’s turning radius will help you manoeuvre into or out of a parking space without hitting something.
#8. What emergency equipment is required in a bus?
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.
#9. To turn right in a vehicle with a lot of off-tracking, you may have to
If you swing wide to the left before you turn right, another vehicle may try to pass you on your right while you are turning, which could lead to a collision. Instead, make the right turn with the rear of your vehicle as close to the curb as possible, cross into the oncoming lane if necessary, and turn wide as you complete the turn. This will deny other vehicles enough room on the right to try to pass you.
#10. Why should you adjust your head restraint so its top is at least level with the top of your head?
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.
#11. 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.
#12. 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.
#13. In a sedan-type vehicle, how many passengers may be seated on your right side?
In a sedan-type vehicle, you may have up to two passengers sitting on your right side, but only if there is enough room for you to operate the vehicle safely and there are designated seating positions with seatbelts in those positions.
#14. When a school bus driver turns on the bus’s alternating flashing red lights, other drivers must
A school bus driver turns on the flashing red lights when the bus stops to pick up or drop off passengers. Drivers approaching the school bus from either direction must stop before reaching the school bus. In British Columbia, this rule applies even if the school bus is stopped on the opposite side of a divided highway.
#15. When driving a school bus, you must NOT do which of the following?
Never do anything that might compromise your passengers’ safety. Don’t open the doors until your vehicle has come to a complete stop, and don’t start moving again until you’ve closed the doors. Don’t refuel the vehicle with passengers aboard, because this could expose them to dangerous fumes or the risk of fire. And of course, always maintain a safe following distance behind the vehicle in front of you.
#16. Which vehicles are required to carry warning devices for use should the vehicle become disabled?
The following commercial vehicles must carry approved warning devices, such as flags, flares, fusees or reflectors: (a) all vehicles with a seating capacity of more than 10 passengers, (b) all commercial vehicles with an overall width of more than 2.3 meters, and (c) all commercial vehicles with a load width of more than 2.3 metres. When parked in the dark, these commercial vehicles must have a minimum of two warning devices.
#17. When transporting persons with disabilities, you should do all of the following EXCEPT
Properly secure wheelchairs, scooters and other mobility aids. If the person with a disability is travelling with a guide dog, you must provide space for the dog in your vehicle so that it will be safe in a collision. Always speak directly to the person with the disability, not to the person’s companion or assistant. And don’t assume the person needs help. Always ask the person before giving help.
#18. According to the British Columbia Driving Commercial Vehicles Manual, 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. More specifically, in an internal-combustion engine, torque is the rotational force that is produced by the engine’s crankshaft.
#19. If a fire starts in your vehicle, you should do which of the following?
If a fire starts under the hood, don’t open it; the additional oxygen will make the fire worse. 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.
#20. To ensure smooth braking in any size vehicle, you should
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.
