Class 4 Mock Test
#1. 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.
#2. 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.
#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. Under the British Columbia Motor Vehicle Act Regulations, how often must commercial vehicles be inspected?
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 the carrier must do these inspections.
#5. A ride-hailing (e.g., Uber) driver is en route in his or her own vehicle to pick up a passenger who requested a ride. Suddenly the driver is involved in a crash. Which insurance will cover the crash?
If the ride-hailing (e.g., Uber) driver has not yet accepted a ride request from a customer, the basic insurance policy of the vehicle’s owner applies. Once the driver accepts a ride request from a customer, the company’s Basic blanket policy applies. ICBC has developed a Basic blanket policy for ride-hailing companies. [“Insurance and Licensing Requirements for Ride-Hailing,” ICBC, https://www.icbc.com/insurance/commercial/Pages/ride-hailing.aspx]
#6. 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
#7. What is total stopping distance?
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.
#8. 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.
#9. To drive defensively, you should
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
#10. 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
#11. Your vehicle’s engine will start to lug (strain) if it is operated
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.
#12. 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.
#13. Every written trip inspection report must include which of the following?
Every written trip inspection report must include the following: (a) the licence plate or unit numbers for the commercial vehicle or trailers, (b) a list of all defects that may affect the safe operation of the vehicle (or stating none if that’s the case), (c) the signature of the person making the report, and (d) the date. This report must be completed before the first trip of the day and submitted to the company within 20 days.
#14. 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.
#15. 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.
#16. Which of the following can impair your driving?
Many legal drugs can cause drowsiness, sedation, or impaired coordination, which can impair your driving. Examples include some prescription painkillers, tranquilizers, and antidepressants; and some over-the-counter sleep aids, allergy medications, and cold medications. Taking such a drug together with alcohol can produce greater impairment than either one alone. If you are uncertain about the effects of a drug you are taking, check the warning label or ask your pharmacist or doctor.
#17. When operating an ambulance, when are you allowed to use flashing red lights and sirens?
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. You may drive an emergency vehicle faster than posted speed limits and drive through red traffic lights or past stop signs if you give other drivers the appropriate warning. Use both the siren and the flashing red lights to warn other drivers.
#18. 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.
#19. Why should you do a shoulder check when making a right turn?
Whenever you plan to change your direction or road position, do a shoulder check to make sure the blind spot on that side is clear. When you’re going to turn right, for example, quickly check to the right to make sure no one is in that space, such as a motorcyclist attempting to pass you on the right.
#20. 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.
