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.

1 / 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

Reduce speed and cover the brake pedal when approaching

Maintain speed to keep momentum

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

2 / 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

3 / 30

When do auxiliary retarders work best?

Whenever you want them to work

At higher speeds

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

At normal speeds

4 / 30

When descending on unfamiliar grades, which statement is false?

On extreme grades, change gears often

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

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

5 / 30

What does water in the brake drums cause?

Reduction in braking ability

Acts as a lubricant

Nothing

It cools down the rotors

6 / 30

While braking on icy roads, what is not recommended?

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

Using snow tires to create better traction

7 / 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

At the front of the left side

8 / 30

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

An uneven load distribution

Low tire pressure

Windy conditions

Loss of air pressure

9 / 30

What does a steady ABS dash light indicate?

It's supposed to stay lit

The vehicle has just been started

A problem with the ABS system

A self-test is being performed

10 / 30

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

The brake system's inability to handle excessive heat

Poor maintenance

Malfunction of a primary air cylinder

No pre-trip inspections

11 / 30

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

Braking from a high rate of speed

None of the above

Braking in rainy conditions

Travelling on downgrades

12 / 30

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

Since 2010

Since 1992

Since 2000

They're not mandatory

13 / 30

What is an Electric Driveline Retarder do?

It's an electromagnet that can pause the driveline

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 in front of the transmission

14 / 30

When using runaway lanes, which does not apply?

You may use these lanes for other purposes

Use the lane before the vehicle is out of control

Use the lane when the brakes no longer control the descent

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

15 / 30

What do exhaust retarders essentially do?

To help block the flow of exhaust

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

To help dissipate the exhaust

To help the back pressure move

16 / 30

What's another work for jackknife?

Push

Yaw

Yank

Pull

17 / 30

With regard to ABS, which statement is false?

ABS brakes work with air brakes and hydraulic brakes

ABS brakes are different with hydraulic brakes compared to air 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

18 / 30

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

Skids or jackknifes

Longer stopping distances

Nothing in particular

Wider turns

19 / 30

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

At higher speeds

With heavy trailer loads

Only in poor weather

Never

20 / 30

What are Hydraulic Driveline Retarders similar to?

Clutch plate

Torque converters

Transmissions

Nothing

21 / 30

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

Apply firm, steady pressure to the brake pedal

Pump the brakes

Read the manufacturer's operational manual for instructions

Be cautious when steering around objects

22 / 30

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

Near the chambers they control

On the wheel itself

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

Wing mounted directly to the relay of the axle group

23 / 30

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

While parked

Never

After start-up and occasionally when braking

After hearing the ABS activate

24 / 30

What does a flashing ABS dash light indicate?

The vehicle has just been started

Controlling the service brakes

A problem with the ABS system

None of the above

25 / 30

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

Use the vehicle's auxiliary retarder

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

Follow advisory speed limits

Follow the actions of all the other drivers

26 / 30

What do ABS brakes do?

Prevents wheel lock-up and skids

None of the above

Allows for a by-pass of the air brake system

Allows for shorter stopping distances

27 / 30

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

More momentum to get up to speed

Better steering ability

Good traction for pulling and braking

No difference compared to weight at the back of a trailer

28 / 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?

Longer braking distances

None of the above

Wheel lock-up

May cause the rear of the trailer to slide and swing

29 / 30

What is Automatic Traction Control (ATC)?

None of the above

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

30 / 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
