On the wheel itself

Wing mounted directly to the relay of the axle group

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

Never

With heavy trailer loads

5 / 30

What are Hydraulic Driveline Retarders similar to?

Clutch plate

Transmissions

Nothing

Torque converters

6 / 30

What is an Electric Driveline Retarder do?

It's an electromagnet that can pause the driveline

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

It's an electromagnet designed to retard drive shaft rotation

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

7 / 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

8 / 30

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

Be cautious when steering around objects

Pump the brakes

Read the manufacturer's operational manual for instructions

Apply firm, steady pressure to the brake pedal

9 / 30

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

Maintain speed to keep momentum

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

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

10 / 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

11 / 30

What is Automatic Traction Control (ATC)?

None of the above

It slows down the vehicle to a crawl

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

It allows the tires to grip the road better

12 / 30

What does a flashing ABS dash light indicate?

A problem with the ABS system

Controlling the service brakes

The vehicle has just been started

None of the above

13 / 30

With regard to ABS, which statement is false?

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

ABS brakes work with air brakes and hydraulic brakes

14 / 30

What's another work for jackknife?

Pull

Yank

Push

Yaw

15 / 30

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

Low tire pressure

An uneven load distribution

Loss of air pressure

Windy conditions

16 / 30

What do ABS brakes do?

Allows for shorter stopping distances

Prevents wheel lock-up and skids

None of the above

Allows for a by-pass of the air brake system

17 / 30

What do exhaust retarders essentially do?

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

To help the back pressure move

To help dissipate the exhaust

To help block the flow of exhaust

18 / 30

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

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

Use a splitter valve

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

19 / 30

When do auxiliary retarders work best?

At higher speeds

Whenever you want them to work

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

At normal speeds

20 / 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

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

Follow advisory speed limits

21 / 30

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

No difference compared to weight at the back of a trailer

Good traction for pulling and braking

More momentum to get up to speed

Better steering ability

22 / 30

When using tire chains, what is not recommended?

In extreme conditions, it may be safer to park

Ensure they are correctly sized and tightly installed

Stop and check tightness after moving one vehicle length

Maintain normal speeds

23 / 30

When descending on unfamiliar grades, which statement is false?

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

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

On extreme grades, change gears often

24 / 30

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

Since 1992

Since 2000

They're not mandatory

Since 2010

25 / 30

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

While parked

After hearing the ABS activate

Never

After start-up and occasionally when braking

26 / 30

While braking on icy roads, what is not recommended?

Light braking to allow for a slow control stop

Locking the wheels slightly to create friction and better traction

Using snow tires to create better traction

Icing chains to create better traction

27 / 30

What does a steady ABS dash light indicate?

A self-test is being performed

It's supposed to stay lit

A problem with the ABS system

The vehicle has just been started

28 / 30

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

Poor maintenance

The brake system's inability to handle excessive heat

No pre-trip inspections

Malfunction of a primary air cylinder

29 / 30

When using runaway lanes, which does not apply?

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

You may use these lanes for other purposes

30 / 30

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

Wider turns

Skids or jackknifes

Longer stopping distances

Nothing in particular
