Ensure they are correctly sized and tightly installed

3 / 30

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

4 / 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

5 / 30

What do exhaust retarders essentially do?

To help block the flow of exhaust

To help dissipate the exhaust

6 / 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

7 / 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

8 / 30

What does a flashing ABS dash light indicate?

A problem with the ABS system

The vehicle has just been started

None of the above

Controlling the service brakes

9 / 30

When using runaway lanes, which does not apply?

Use the lane before the vehicle is out of control

You may use these lanes for other purposes

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

10 / 30

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

Braking in rainy conditions

Braking from a high rate of speed

None of the above

Travelling on downgrades

11 / 30

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

Loss of air pressure

An uneven load distribution

Windy conditions

Low tire pressure

12 / 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

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 pause the driveline

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

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

14 / 30

What are Hydraulic Driveline Retarders similar to?

Transmissions

Torque converters

Clutch plate

Nothing

15 / 30

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

After hearing the ABS activate

Never

After start-up and occasionally when braking

While parked

16 / 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

Wing mounted directly to the relay of the axle group

On the wheel itself

Near the chambers they control

17 / 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

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

18 / 30

When do auxiliary retarders work best?

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

At normal speeds

Whenever you want them to work

At higher speeds

19 / 30

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

At the rear of the left side

At the rear of the right side

At the front of the left side

At the front of the right side

20 / 30

What's another work for jackknife?

Push

Yank

Pull

Yaw

21 / 30

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

With heavy trailer loads

Never

Only in poor weather

At higher speeds

22 / 30

What do ABS brakes do?

Allows for shorter stopping distances

Prevents wheel lock-up and skids

Allows for a by-pass of the air brake system

None of the above

23 / 30

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

Be cautious when steering around objects

Apply firm, steady pressure to the brake pedal

Pump the brakes

Read the manufacturer's operational manual for instructions

24 / 30

What does water in the brake drums cause?

It cools down the rotors

Nothing

Acts as a lubricant

Reduction in braking ability

25 / 30

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

Since 2000

Since 1992

Since 2010

They're not mandatory

26 / 30

When descending on unfamiliar grades, which statement is false?

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

On extreme grades, change gears often

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

27 / 30

What does a steady ABS dash light indicate?

A problem with the ABS system

The vehicle has just been started

It's supposed to stay lit

A self-test is being performed

28 / 30

With regard to ABS, which statement is false?

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

ABS brakes are different with hydraulic brakes compared to air brakes

Make sure you know which units in a combination have ABS

ABS brakes work with air brakes and hydraulic brakes

29 / 30

While braking on icy roads, what is not recommended?

Locking the wheels slightly to create friction and better traction

Light braking to allow for a slow control stop

Using snow tires to create better traction

Icing chains to create better traction

30 / 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

None of the above

Longer braking distances

Wheel lock-up
