None of the above

Controlling the service brakes

A problem with the ABS system

4 / 30

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

Braking from a high rate of speed

Braking in rainy conditions

None of the above

Travelling on downgrades

5 / 30

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

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

Maintain speed to keep momentum

Reduce speed and cover the brake pedal when approaching

6 / 30

When do auxiliary retarders work best?

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

Whenever you want them to work

At higher speeds

At normal speeds

7 / 30

When descending on unfamiliar grades, which statement is false?

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

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

8 / 30

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

Use a splitter valve

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

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

9 / 30

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

Longer stopping distances

Nothing in particular

Skids or jackknifes

Wider turns

10 / 30

What do exhaust retarders essentially do?

To help dissipate the exhaust

To help the back pressure move

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

To help block the flow of exhaust

11 / 30

What's another work for jackknife?

Push

Pull

Yank

Yaw

12 / 30

What does a steady ABS dash light indicate?

A self-test is being performed

The vehicle has just been started

It's supposed to stay lit

A problem with the ABS system

13 / 30

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

Never

After hearing the ABS activate

After start-up and occasionally when braking

While parked

14 / 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

15 / 30

What are Hydraulic Driveline Retarders similar to?

Clutch plate

Nothing

Transmissions

Torque converters

16 / 30

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

With heavy trailer loads

Only in poor weather

At higher speeds

Never

17 / 30

What does water in the brake drums cause?

Nothing

Reduction in braking ability

Acts as a lubricant

It cools down the rotors

18 / 30

When using tire chains, what is not recommended?

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

Maintain normal speeds

19 / 30

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

Pump the brakes

Be cautious when steering around objects

Read the manufacturer's operational manual for instructions

Apply firm, steady pressure to the brake pedal

20 / 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 right side

At the front of the left side

21 / 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

Longer braking distances

May cause the rear of the trailer to slide and swing

22 / 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

23 / 30

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

They're not mandatory

Since 1992

Since 2000

Since 2010

24 / 30

When using runaway lanes, which does not apply?

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

Use the lane when the brakes no longer control the descent

25 / 30

What is an Electric Driveline Retarder do?

It's an electromagnet that can pause the driveline

It's an electromagnet designed to retard drive shaft rotation

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

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

26 / 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

27 / 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

Better steering ability

More momentum to get up to speed

28 / 30

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

Poor maintenance

No pre-trip inspections

The brake system's inability to handle excessive heat

Malfunction of a primary air cylinder

29 / 30

What is Automatic Traction Control (ATC)?

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

None of the above

It allows the tires to grip the road better

It slows down the vehicle to a crawl

30 / 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 relay of the axle group

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