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.

What is an Electric Driveline Retarder do?

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

It's an electromagnet designed to retard drive shaft rotation

It's an electromagnet that can pause the driveline

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

2 / 30

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

Better steering ability

More momentum to get up to speed

Good traction for pulling and braking

No difference compared to weight at the back of a trailer

3 / 30

What are Hydraulic Driveline Retarders similar to?

Torque converters

Nothing

Clutch plate

Transmissions

4 / 30

When do auxiliary retarders work best?

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

Whenever you want them to work

At normal speeds

At higher speeds

5 / 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?

Wheel lock-up

None of the above

May cause the rear of the trailer to slide and swing

Longer braking distances

6 / 30

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

Reduce speed and cover the brake pedal when approaching

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

Maintain speed to keep momentum

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

7 / 30

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

None of the above

Travelling on downgrades

Braking in rainy conditions

Braking from a high rate of speed

8 / 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

Use a splitter valve

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

9 / 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

10 / 30

Antilock Brake Systems (ABS) are handled by sensors, modulators and a computer. Which statement is false? The modulators can be located...

Wing mounted directly to the quick release valve of the axle group

On the wheel itself

Near the chambers they control

Wing mounted directly to the relay of the axle group

11 / 30

When descending on unfamiliar grades, which statement is false?

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

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

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

On extreme grades, change gears often

12 / 30

What does a flashing ABS dash light indicate?

None of the above

A problem with the ABS system

Controlling the service brakes

The vehicle has just been started

13 / 30

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

Longer stopping distances

Nothing in particular

Skids or jackknifes

Wider turns

14 / 30

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

Apply firm, steady pressure to the brake pedal

Read the manufacturer's operational manual for instructions

Pump the brakes

Be cautious when steering around objects

15 / 30

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

Low tire pressure

Loss of air pressure

Windy conditions

An uneven load distribution

16 / 30

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

Malfunction of a primary air cylinder

Poor maintenance

The brake system's inability to handle excessive heat

No pre-trip inspections

17 / 30

With regard to ABS, which statement is false?

ABS brakes work with air brakes and hydraulic brakes

If the tractor or trailer do not have ABS, use a light, steady braking technique

Make sure you know which units in a combination have ABS

ABS brakes are different with hydraulic brakes compared to air brakes

18 / 30

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

At the front of the right side

At the rear of the right side

At the front of the left side

At the rear of the left side

19 / 30

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

Use the vehicle's auxiliary retarder

Follow the actions of all the other drivers

Follow advisory speed limits

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

20 / 30

What do exhaust retarders essentially do?

To help dissipate the exhaust

To help the back pressure move

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

To help block the flow of exhaust

21 / 30

What does water in the brake drums cause?

Acts as a lubricant

Nothing

It cools down the rotors

Reduction in braking ability

22 / 30

When using runaway lanes, which does not apply?

Use the lane when the brakes no longer control the descent

Use the lane before the vehicle is out of control

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

You may use these lanes for other purposes

23 / 30

What's another work for jackknife?

Push

Pull

Yank

Yaw

24 / 30

While braking on icy roads, what is not recommended?

Using snow tires to create better traction

Light braking to allow for a slow control stop

Icing chains to create better traction

Locking the wheels slightly to create friction and better traction

25 / 30

When were ABS brake mandatory on all air brake trucks, buses and trailers?

They're not mandatory

Since 2000

Since 1992

Since 2010

26 / 30

When using tire chains, what is not recommended?

Ensure they are correctly sized and tightly installed

Maintain normal speeds

Stop and check tightness after moving one vehicle length

In extreme conditions, it may be safer to park

27 / 30

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

Never

With heavy trailer loads

At higher speeds

Only in poor weather

28 / 30

What does a steady ABS dash light indicate?

A problem with the ABS system

A self-test is being performed

It's supposed to stay lit

The vehicle has just been started

29 / 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

30 / 30

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

After hearing the ABS activate

While parked

Never

After start-up and occasionally when braking
