Class 4 Mock Test
#1. 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.
#2. If you are unable to keep up with traffic on a steep grade, what should you do?
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.
#3. 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.
#4. 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
#5. 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.
#6. If tire tread damage is longer than _______, the tire should be considered defective. 2.5 cm 3.5 cm 4.5 cm 1.5 cm
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.
#7. A controlled railway crossing may have
All vehicles must stop at controlled railway crossings if signaled to do so. A controlled crossing has a flag person, stop sign, crossing gate or an electric or mechanical signaling device.
#8. 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.
#9. Drivers on Cycle 2 must not drive after completing ____ hours of on-duty time in 14 consecutive days.
Drivers on Cycle 2 (a 14-day cycle) must not drive after completing 120 on-duty hours in 14 consecutive days. Furthermore, they must take at least 24 consecutive hours off duty prior to accumulating 70 hours of on-duty time
#10. 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.
#11. When approaching an intersection at which you intend to turn, you should
When approaching an intersection, don’t change lanes or pass or overtake other vehicles. If you intend to turn at the intersection, get in the proper lane well before the intersection and signal other drivers to show them you intend to turn. Reduce your speed gradually before entering the intersection.
#12. If someone is tailgating you, what should you do?
If you are being followed too closely (tailgated), slow down gradually to increase your following distance and give the driver behind you more time to react. This can reduce your chances of being struck from behind should you need to stop. Avoid tricks such as flashing your brake lights. And never increase your speed in an attempt to appease or outdistance the tailgater. No speed is too fast for some tailgaters.
#13. Which of the following statements about off-tracking are true?
Off-tracking is the difference between the path of the front wheels and the path of the rear wheels when the vehicle is on a curve. The greater the distance between the front wheels and the rear wheels of the vehicle or combination of vehicles, the greater the off-tracking. When a tractor-trailer turns right, the front end must turn wide enough around the corner so the rear end won’t run over the curb.
#14. 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.
#15. How should you upshift a gasoline-powered vehicle that is not equipped with a governor?
Smaller commercial vehicles usually don’t have governors to regulate engine rpm and the amount of fuel burned. To upshift a gasoline-powered vehicle that is not equipped with a governor, perform the following steps: 1. Start in low gear. Use only enough throttle to start the vehicle moving. 2. When the engine begins to accelerate, quickly shift into the next gear. Shift into higher gears as soon as you have the power. 3. As your vehicle’s speed increases and you begin shifting into the higher gears, allow the engine to develop more power before each shift so the rate of acceleration increases. 4. As you complete each shift, engage the clutch smoothly, and engage the throttle at the same time.
#16. 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]
#17. Airbags are
Airbags and head restraints aren’t legally required on large commercial vehicles, although some vehicles may have them. The driver’s-side airbag deploys out of the steering wheel at very high speed, which can seriously injure you if you move forward in a crash. Therefore, even if your vehicle is equipped with airbags, you must wear your seatbelt. You must also allow at least 25 cm (10 inches) of space between your chest and the airbag unit in the steering wheel. These measures will minimize the risk of injury if the bag deploys
#18. 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
#19. 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.
#20. 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.
