Alberta Air Brake Test 06

Passing the Alberta Air Brake test requires a high level of competency and knowledge, as well as a significant amount of practice and preparation, which you have undoubtedly achieved. It’s no small feat to earn an endorsement for operating vehicles with air brakes, and your accomplishment should be celebrated. Your success highlights the importance of studying diligently, asking for help when needed, and staying motivated throughout the learning process.

3 / 30

When descending on unfamiliar grades, which statement is false?

Select a low gear and turn on the retarder before the hill is crested

There is a balance between the retarder, speed, load and grade is reached

On extreme grades, change gears often

Stay in a low gear until the steepest part of the descent

4 / 30

Trailers equipped with ABS brakes will have an ABS warning light. Where is this light located?

At the rear of the right side

At the rear of the left side

At the front of the right side

5 / 30

If speed increases on a downgrade, what should you not do?

Repeat this process as necessary until the retarder can maintain the speed without service brakes

Continue down the hill using the auxiliary retarder to control the speed

Use a splitter valve

6 / 30

If approaching a large amount of water on the road, what should you not do?

Apply slight constant pressure to reduce the amount of water entering between the brake drums and shoes

Test the brakes after exiting the water to help to dry them out

Reduce speed and cover the brake pedal when approaching

Maintain speed to keep momentum

7 / 30

While braking on icy roads, what is not recommended?

Icing chains to create better traction

Locking the wheels slightly to create friction and better traction

Using snow tires to create better traction

Light braking to allow for a slow control stop

8 / 30

At what point do air brakes generate the most ongoing heat?

Braking in rainy conditions

Braking from a high rate of speed

Travelling on downgrades

None of the above

9 / 30

What does a steady ABS dash light indicate?

The vehicle has just been started

It's supposed to stay lit

A self-test is being performed

A problem with the ABS system

10 / 30

What does a flashing ABS dash light indicate?

The vehicle has just been started

A problem with the ABS system

Controlling the service brakes

None of the above

11 / 30

What do exhaust retarders essentially do?

To help the back pressure stays within the engine's back pressure capacity

To help block the flow of exhaust

To help dissipate the exhaust

To help the back pressure move

12 / 30

What potential problem can happen while applying brakes on combination vehicles?

Skids or jackknifes

Longer stopping distances

Wider turns

Nothing in particular

13 / 30

What is an Electric Driveline Retarder do?

It's an electromagnet designed to retard drive shaft rotation

It's an electromagnet that can in front of the transmission

It's an electromagnet that can pause the driveline

It's an electromagnet that can be placed beside an axle

14 / 30

What do ABS brakes do?

None of the above

Prevents wheel lock-up and skids

Allows for a by-pass of the air brake system

Allows for shorter stopping distances

15 / 30

To brake safely with ABS, what should you not do?

Pump the brakes

Read the manufacturer's operational manual for instructions

Be cautious when steering around objects

Apply firm, steady pressure to the brake pedal

16 / 30

Brake management systems are effective, when should drivers rely on them?

Only in poor weather

Never

At higher speeds

With heavy trailer loads

17 / 30

What is the cause of almost all of the brake failures and runaway crashes?

No pre-trip inspections

Malfunction of a primary air cylinder

The brake system's inability to handle excessive heat

Poor maintenance

18 / 30

What are Hydraulic Driveline Retarders similar to?

Transmissions

Torque converters

Clutch plate

Nothing

19 / 30

When using tire chains, what is not recommended?

In extreme conditions, it may be safer to park

Maintain normal speeds

Ensure they are correctly sized and tightly installed

Stop and check tightness after moving one vehicle length

20 / 30

When do auxiliary retarders work best?

At lower vehicle speeds, and with the engine just under the rated rpm

At higher speeds

At normal speeds

Whenever you want them to work

21 / 30

When using runaway lanes, which does not apply?

You may use these lanes for other purposes

A narrow steep runaway lane will be very difficult to use if the vehicle is out of control

Use the lane before the vehicle is out of control

Use the lane when the brakes no longer control the descent

22 / 30

What is the biggest challenge for combination units causing the loss of brake balance?

Windy conditions

Low tire pressure

An uneven load distribution

Loss of air pressure

23 / 30

What is Automatic Traction Control (ATC)?

It uses ABS sensors to monitor drive-wheel spin on slippery roads

It slows down the vehicle to a crawl

It allows the tires to grip the road better

None of the above

24 / 30

To descend safely in rural areas, which statement is false?

Follow the actions of all the other drivers

Use the vehicle's auxiliary retarder

Follow advisory speed limits

Use 4-way flashers and stay in the right lane when possible

25 / 30

What does water in the brake drums cause?

Reduction in braking ability

Acts as a lubricant

Nothing

It cools down the rotors

26 / 30

What's another work for jackknife?

Yank

Push

Pull

Yaw

When should the driver check the ABS light on the trailer?

After hearing the ABS activate

After start-up and occasionally when braking

Never

While parked

29 / 30

The brakes under the empty rear of the trailer receiving the same amount of application air pressure as the drive axles, without the load to hold them down onto the ground, what can happen?

May cause the rear of the trailer to slide and swing

Wheel lock-up

Longer braking distances

None of the above

30 / 30

What will a heavy load at the front of a trailer will cause the drive axles to have?

Good traction for pulling and braking

No difference compared to weight at the back of a trailer

More momentum to get up to speed

Better steering ability
