Pump the brakes

Read the manufacturer's operational manual for instructions

6 / 30

While braking on icy roads, what is not recommended?

Using snow tires to create better traction

Icing chains to create better traction

Light braking to allow for a slow control stop

7 / 30

What do exhaust retarders essentially do?

To help block the flow of exhaust

To help the back pressure move

To help dissipate the exhaust

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

8 / 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?

Wheel lock-up

May cause the rear of the trailer to slide and swing

None of the above

Longer braking distances

9 / 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

10 / 30

What does a flashing ABS dash light indicate?

Controlling the service brakes

None of the above

The vehicle has just been started

A problem with the ABS system

11 / 30

With regard to ABS, which statement is false?

ABS brakes are different with hydraulic brakes compared to air brakes

ABS brakes work with air brakes and hydraulic brakes

Make sure you know which units in a combination have ABS

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

12 / 30

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

At the front of the left side

At the front of the right side

At the rear of the right side

At the rear of the left side

13 / 30

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

Since 1992

They're not mandatory

Since 2010

Since 2000

14 / 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

15 / 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

Near the chambers they control

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

On the wheel itself

16 / 30

What are Hydraulic Driveline Retarders similar to?

Torque converters

Clutch plate

Transmissions

Nothing

17 / 30

When using tire chains, what is not recommended?

Stop and check tightness after moving one vehicle length

Ensure they are correctly sized and tightly installed

In extreme conditions, it may be safer to park

Maintain normal speeds

18 / 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 that can be placed beside an axle

It's an electromagnet designed to retard drive shaft rotation

19 / 30

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

More momentum to get up to speed

Good traction for pulling and braking

No difference compared to weight at the back of a trailer

Better steering ability

20 / 30

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

Low tire pressure

An uneven load distribution

Windy conditions

Loss of air pressure

21 / 30

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

Skids or jackknifes

Longer stopping distances

Wider turns

Nothing in particular

22 / 30

What does a steady ABS dash light indicate?

The vehicle has just been started

A self-test is being performed

It's supposed to stay lit

A problem with the ABS system

23 / 30

What is Automatic Traction Control (ATC)?

It allows the tires to grip the road better

None of the above

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

It slows down the vehicle to a crawl

24 / 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

25 / 30

What do ABS brakes do?

Allows for a by-pass of the air brake system

Prevents wheel lock-up and skids

None of the above

Allows for shorter stopping distances

26 / 30

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

Malfunction of a primary air cylinder

Poor maintenance

The brake system's inability to handle excessive heat

No pre-trip inspections

27 / 30

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

Use a splitter valve

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

28 / 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
