Class 4 Mock Test
#1. Different-sized tires can
Using tires of different sizes or different types (e.g., radial and bias ply) on the same axle can adversely affect handling, especially when braking.
#2. If you are parking a vehicle on a downgrade, you should
If you’re parking any type of motor vehicle (even a passenger car) on a downgrade, turn your wheels toward the edge of the roadway. If your vehicle’s brakes fail, your vehicle will roll toward the edge of the roadway, not into traffic.
#3. When you conduct a pre-trip inspection of your vehicle, all of the following should be considered major defects EXCEPT
National Safety Code (NSC) Standard 13 prescribes daily trip inspection requirements. According to Standard 13, a vehicle with a major defect may not be driven until the defect is repaired. Examples of major defects are a broken seatbelt, an inoperative parking or emergency brake, and an inoperative rearmost turn signal lamp. A missing fuel tank cap is considered a minor defect unless fuel is leaking from the tank, which is considered a major defect.
#4. How should you drive through a large amount of water on the roadway?
If you must drive through water, slow down and place a slight drag (that is, apply a slight constant pressure) on the brakes while you drive through the water. The slight drag placed on the brakes will reduce the amount of water and other contaminants that enter the brakes.
#5. Why should you use extra caution at railway crossings in rural areas?
For a variety of reasons, you should use extra caution when you cross railway tracks in rural areas. In rural areas, approach grades may be steeper, snow banks may be higher, brush can affect your visibility, there are fewer automated warning systems, and more of these rural crossings may be humpback crossings.
#6. To stop quickly in an emergency, what should you do if your vehicle has antilock brakes (ABS)?
If you must stop in an emergency, apply firm, hard, continuous pressure to the brake pedal until you come to a complete stop. Don’t worry about possibly locking the wheels. If the ABS computer senses that a wheel is about to lock, it will automatically release that brake to get the wheel rolling again, then reapply the brake. When ABS is working, some pulsation of the brake pedal is normal
#7. 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.
#8. A Slow-Moving Vehicle sign should be placed on any vehicle that travels no faster than
A Slow-Moving Vehicle emblem is an orange triangle with a red border, affixed to the rear of the vehicle. It alerts other drivers that the vehicle travels at 40 km/h or less.
#9. How do you ease your vehicle into a smooth stop?
To brake, press the brake pedal gradually yet firmly. Just before your vehicle comes to a full stop, reduce pressure on the brake pedal. This will prevent your vehicle from jerking back, enabling you to make a smooth stop
#10. You may let passengers on or off your vehicle on the roadway only where your vehicle is visible from at least ________ in both directions.
To let passengers on or off your vehicle, stop in a location where (a) there is at least three metres (about 10 feet) of space on the left side of your vehicle so that traffic may pass, and (b) other drivers can see your vehicle from at least 85 metres (285 feet) in front and behind.
#11. Why are hours of service regulations in place?
Hours of service regulations are designed to limit the time you can spend driving. Statistics show that a fatigued driver is more likely to become involved in a crash.
#12. How often should you look at your mirrors?
While you’re driving, keep your eyes moving. Scan the road well ahead. Then scan the road from one side of the road to the other. Then check your mirrors. Keep repeating this cycle every 5 to 8 seconds.
#13. 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.
#14. When you see a potential hazard in your danger zone, you should
A hazard is a road user or road condition (such as a busy intersection) that presents a possible danger. A hazard is not an emergency – but it can quickly become one. When you spot a hazard, prepare to deal with any emergency that might develop. For example, cover the brake pedal with your foot to shorten your reaction time. Keep your eye on that hazard and be ready to act instantly if necessary.
#15. When can flashing amber lights be mounted on a vehicle?
Flashing amber lights are used on construction vehicles, towing vehicles, tow cars that are attending, snow-removal equipment, sanding equipment, pilot cars, and vehicles that are required by permit to use them, such as some oversize vehicles or vehicles carrying oversize loads. If a vehicle is going to haul an oversize load, the driver must obtain a Commercial Vehicle Safety & Enforcement permit from ICBC. This will allow the driver to mount flashing amber or red lights on the vehicle as well as the appropriate oversize signs.
#16. 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.
#17. 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.
#18. When you're driving an ambulance in response to an emergency call, you are allowed to do which of the following?
If you are transporting a patient or responding to an emergency call, you may exceed posted speed limits and drive through red traffic lights or past stop signs if you give other drivers the appropriate warning. (Use both the flashing red lights and the siren to warn other drivers.) You may disregard rules and traffic control devices governing direction of movement or turning in specified directions. You may also send email or text messages from a hand-held cell phone if you are doing so in the performance of your duties. [Sections 122 and 214.2, British Columbia Motor Vehicle Act]
#19. 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
#20. When should you check the tire pressures?
Check tire pressures when the tires are cool. Tire pressures increase as the tires warm up. Tires that appear properly inflated when they are warm may become underinflated as they cool. Use a tire pressure gauge to get accurate readings.
