7 / 30

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

Braking from a high rate of speed

Travelling on downgrades

None of the above

Braking in rainy conditions

8 / 30

What does a flashing ABS dash light indicate?

The vehicle has just been started

Controlling the service brakes

None of the above

A problem with the ABS system

9 / 30

10 / 30

What's another work for jackknife?

Yank

Push

Yaw

Pull

11 / 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 front of the left side

At the rear of the right side

At the rear of the left side

12 / 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

13 / 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

14 / 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?

None of the above

Wheel lock-up

May cause the rear of the trailer to slide and swing

Longer braking distances

15 / 30

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

On the wheel itself

Near the chambers they control

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

Wing mounted directly to the relay of the axle group

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

When using tire chains, what is not recommended?

In extreme conditions, it may be safer to park

Maintain normal speeds

Stop and check tightness after moving one vehicle length

Ensure they are correctly sized and tightly installed

18 / 30

What are Hydraulic Driveline Retarders similar to?

Clutch plate

Torque converters

Transmissions

Nothing

19 / 30

When do auxiliary retarders work best?

Whenever you want them to work

At normal speeds

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

At higher speeds

20 / 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

21 / 30

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

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

Follow advisory speed limits

Follow the actions of all the other drivers

Use the vehicle's auxiliary retarder

22 / 30

What do exhaust retarders essentially do?

To help the back pressure move

To help dissipate the exhaust

To help block the flow of exhaust

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

23 / 30

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

Maintain speed to keep momentum

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

24 / 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

25 / 30

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

Be cautious when steering around objects

Pump the brakes

Apply firm, steady pressure to the brake pedal

Read the manufacturer's operational manual for instructions

26 / 30

What does water in the brake drums cause?

Reduction in braking ability

It cools down the rotors

Nothing

Acts as a lubricant

27 / 30

While braking on icy roads, what is not recommended?

Using snow tires to create better traction

Icing chains to create better traction

Locking the wheels slightly to create friction and better traction

Light braking to allow for a slow control stop

28 / 30

When descending on unfamiliar grades, which statement is false?

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

On extreme grades, change gears often

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

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

29 / 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

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

Use the lane when the brakes no longer control the descent

30 / 30

What is Automatic Traction Control (ATC)?

It slows down the vehicle to a crawl

It allows the tires to grip the road better

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

None of the above
