6 / 30

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

At higher speeds

With heavy trailer loads

Only in poor weather

Never

7 / 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

8 / 30

While braking on icy roads, what is not recommended?

Icing chains to create better traction

Light braking to allow for a slow control stop

Using snow tires to create better traction

Locking the wheels slightly to create friction and better traction

9 / 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

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 relay of the axle group

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

On the wheel itself

Near the chambers they control

11 / 30

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

Poor maintenance

Malfunction of a primary air cylinder

No pre-trip inspections

The brake system's inability to handle excessive heat

12 / 30

When do auxiliary retarders work best?

Whenever you want them to work

At higher speeds

At normal speeds

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

13 / 30

What does a flashing ABS dash light indicate?

The vehicle has just been started

A problem with the ABS system

None of the above

Controlling the service brakes

14 / 30

When using tire chains, what is not recommended?

Maintain normal speeds

In extreme conditions, it may be safer to park

Stop and check tightness after moving one vehicle length

Ensure they are correctly sized and tightly installed

15 / 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

16 / 30

What's another work for jackknife?

Yaw

Yank

Pull

Push

17 / 30

What does a steady ABS dash light indicate?

A problem with the ABS system

It's supposed to stay lit

A self-test is being performed

The vehicle has just been started

18 / 30

What are Hydraulic Driveline Retarders similar to?

Transmissions

Clutch plate

Torque converters

Nothing

19 / 30

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

Pump the brakes

Apply firm, steady pressure to the brake pedal

Read the manufacturer's operational manual for instructions

Be cautious when steering around objects

20 / 30

What does water in the brake drums cause?

Acts as a lubricant

It cools down the rotors

Nothing

Reduction in braking ability

21 / 30

What do ABS brakes do?

Allows for a by-pass of the air brake system

None of the above

Allows for shorter stopping distances

Prevents wheel lock-up and skids

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?

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

24 / 30

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

None of the above

Braking from a high rate of speed

Braking in rainy conditions

Travelling on downgrades

25 / 30

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

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

Follow the actions of all the other drivers

Follow advisory speed limits

Use the vehicle's auxiliary retarder

26 / 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

27 / 30

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

After start-up and occasionally when braking

Never

While parked

After hearing the ABS activate

28 / 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

More momentum to get up to speed

Good traction for pulling and braking

Better steering ability

29 / 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

30 / 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
