Class 4 Mock Test

#1. 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.

#2. 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.

#3. If a peace officer asks for your logbook and supporting documents, what documents should you provide?

Supporting documents may include bills of lading, shipping documents, fuel receipts, and accommodation receipts for expenses incurred along the route. (A bill of lading is issued by a carrier to acknowledge receipt of cargo for shipment by the carrier.)

#4. Why must you prevent tiedowns from rubbing against your load?

Tiedowns can become abraded or frayed by rubbing against the cargo. Eventually the tiedown may tear open. To prevent this, use dunnage to separate the cargo from its tiedowns.

#5. 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

#6. 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.

#7. The Motor Vehicle Act gives public transit buses the right-of-way. What does this mean?

The Motor Vehicle Act gives public transit buses the right-of-way when a bus driver signals to move from the curb lane or a bus stop into the traffic flow and the bus displays a sign telling motorists to yield. This rule applies to locations where the speed limit is less than 60 km/h. Of course, the bus driver, like any other driver who legally has the right-of-way, is still responsible for making sure that it’s safe to pull out into traffic.

#8. 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.

#9. 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.

#10. During your pre-trip inspection, you discover a defect that does not affect the safe operation of the vehicle. What should you do?

You must note all defects on your inspection report. If the defect isn’t safety related, your report must say so. Then the defect can be repaired after your trip is over.

#11. Making eye contact with cyclists around your vehicle

An important part of sharing the road with cyclists is being able to communicate with them. Recognize the hand signals they use. Make eye contact if you can; cyclists often use eye contact to communicate. Don’t startle cyclists by honking your horn unnecessarily.

#12. The maximum speed in an alley is _______ unless otherwise posted.

The maximum speed in an alley is 20 km/h unless otherwise posted.

#13. What function does the alcohol evaporator perform?

When the air compressor runs, an alcohol evaporator puts alcohol vapor into the air brake system to help prevent water in the lines or valves from freezing. Ice in the lines or valves can cause them to stop working.

#14. 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.

#15. 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.

#16. 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.

#17. Which of the following can increase the length of your danger zone (as defined in the British Columbia Driving Commercial Vehicles Manual)?

The section of road that your vehicle travels through before it can stop is called the vehicle’s danger zone, because it’s physically impossible for you to stop the vehicle in time to avoid a collision with any object or person. As your speed increases, the length of your danger zone increases. Less than ideal road conditions, such as rain, snow, ice or gravel increase the length of your danger zone. Driving fast under these road conditions increases your danger zone even more. Finally, heavy commercial vehicles have more kinetic energy than cars travelling at the same speed and therefore take longer to brake to a stop.

#18. Which of the following may reduce the amount of steering control you have?

For best traction, tires should have adequate tread and be properly inflated. Overinflating a tire causes excess wear in the centre part of its tread. An overinflated tire has less tread surface in contact with the road surface. Less contact between your tire and the road means less traction. Underinflating a tire causes excess wear on the outer edges of its tread. Under wet conditions, an underinflated tire will not channel the water away very well, which may lead to hydroplaning.

#19. 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.

#20. Which of the following licence classes does not allow you to drive an ambulance with passengers?

A Class 3 licence allows you to drive a box truck (possibly towing a trailer not equipped with air brakes) and any Class 5 vehicle, such as a passenger car. However, a Class 3 licence does not allow you to drive a Class 4 vehicle, such as an ambulance or taxi.
