Class 4 Mock Test
#1. 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?
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
#2. 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.
#3. 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.
#4. Stopping on icy roads requires
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.
#5. Why do the hours of service regulations exist?
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.
#6. After working 120 hours in a 14-day cycle, drivers must take ____ consecutive hours of off-duty time before taking 70 hours of on-duty time.
Drivers working on Cycle 2 must not drive after completing 120 hours in 14 days, and they must take at least 24 consecutive hours off duty before accumulating the next 70 hours of on-duty time.
#7. Which of the following is not a Class 4 vehicle?
Class 4 motor vehicles include ambulances, taxis, and buses with a seating capacity of 24 passengers or less.
#8. 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.
#9. 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.
#10. How often should you inspect your vehicle?
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 your company must perform these inspections.
#11. Under ideal driving conditions in City, passenger cars and light trucks should maintain a following distance of at least ________ behind the vehicle ahead.
Drivers of passenger cars and light trucks should maintain a following distance of at least two seconds behind the vehicle ahead. Drivers of buses, trucks, or other heavy vehicles should maintain a following distance of at least five seconds. If driving conditions are less than ideal, they should increase their following distance still further.
#12. If you're on a 14-day cycle, what is the maximum number of hours you can drive within 14 consecutive days?
Drivers working on Cycle 2 (the 14-day cycle) must not drive after completing 120 hours in 14 days, and they must take at least 24 consecutive hours off duty before accumulating the next 70 hours of on-duty time.
#13. If you need to keep a daily log, what else do you need to keep with you?
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.
#14. How far back should you stay when following an emergency vehicle with flashing lights and siren on?
When following an emergency vehicle with flashing lights and siren on, stay back about 150 metres. At 90 km/h, this corresponds to a following distance of six seconds.
#15. At which of the following engine speeds should you drive your vehicle?
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.
#16. The way in which a vehicle can be manoeuvred depends on which of the following?
Many commercial vehicles are larger, heavier and longer than other vehicles on the road. The extra size, weight and length affect the way these vehicles move, especially around turns and while backing up. Shorter vehicles tend to have smaller turning circles, and vehicles with shorter turning circles can make tighter turns. Some buses have a conventional configuration in which the driver’s seat is positioned behind the steering axle. However, other buses are forward-control vehicles in which the driver’s seat is in front of the steering axle. This affects both the vehicle’s turning radius and the driver’s viewpoint when turning. When driving a forward-control vehicle, you must start your turn at a slightly different point on the turning path than when you’re driving a vehicle with a conventional configuration.
#17. What should you do before making a left turn?
To turn left, first signal your intention to turn left, and approach the intersection in the leftmost lane that is going in your direction. If that is not a left-turn lane, move to the left side of the lane. Yield the right-of-way to pedestrians and oncoming vehicles. When it’s safe, turn into the nearest lane in which traffic is moving in the direction that you want to go.
#18. 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.
#19. If tire tread damage is longer than _______, the tire should be considered defective.
A tire should be considered defective if it has any tread damage (such as cuts, cracks or snags) that is longer than 2.5 cm (1 inch) and deep enough to expose the ply cords.
#20. A tractor-trailer travelling at high speeds creates air turbulence in which of the following areas?
Large vehicles travelling at high speeds create air turbulence that can be hazardous to smaller vehicles. A tractor-trailer creates air turbulence directly in front of the truck, alongside the cab, by the rear area of the trailer, and at the immediate rear of the trailer.
