Follow advisory speed limits

Use the vehicle's auxiliary retarder

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

Follow the actions of all the other drivers

5 / 30

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

Better steering ability

Good traction for pulling and braking

No difference compared to weight at the back of a trailer

More momentum to get up to speed

6 / 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

Maintain normal speeds

Ensure they are correctly sized and tightly installed

7 / 30

What does water in the brake drums cause?

It cools down the rotors

Reduction in braking ability

Nothing

Acts as a lubricant

8 / 30

What's another work for jackknife?

Yank

Pull

Push

Yaw

9 / 30

When descending on unfamiliar grades, which statement is false?

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

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

10 / 30

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

The brake system's inability to handle excessive heat

Malfunction of a primary air cylinder

Poor maintenance

No pre-trip inspections

11 / 30

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

None of the above

Braking in rainy conditions

Travelling on downgrades

Braking from a high rate of speed

12 / 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 normal speeds

At higher speeds

13 / 30

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

Windy conditions

Low tire pressure

An uneven load distribution

Loss of air pressure

14 / 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 work with air brakes and hydraulic brakes

ABS brakes are different with hydraulic brakes compared to air brakes

Make sure you know which units in a combination have ABS

15 / 30

While braking on icy roads, what is not recommended?

Using snow tires to create better traction

Light braking to allow for a slow control stop

Locking the wheels slightly to create friction and better traction

Icing chains to create better traction

16 / 30

What is an Electric Driveline Retarder do?

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

It's an electromagnet designed to retard drive shaft rotation

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

It's an electromagnet that can pause the driveline

17 / 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?

Longer braking distances

None of the above

May cause the rear of the trailer to slide and swing

Wheel lock-up

18 / 30

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

While parked

After start-up and occasionally when braking

After hearing the ABS activate

Never

19 / 30

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

Maintain speed to keep momentum

Reduce speed and cover the brake pedal when approaching

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

20 / 30

What do exhaust retarders essentially do?

To help block the flow of exhaust

To help dissipate the exhaust

To help the back pressure move

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

21 / 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

22 / 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 rear of the right side

At the front of the left side

At the rear of the left side

23 / 30

What is Automatic Traction Control (ATC)?

It slows down the vehicle to a crawl

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

24 / 30

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

Pump the brakes

Be cautious when steering around objects

Apply firm, steady pressure to the brake pedal

Read the manufacturer's operational manual for instructions

25 / 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

26 / 30

What does a flashing ABS dash light indicate?

The vehicle has just been started

None of the above

Controlling the service brakes

A problem with the ABS system

27 / 30

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

Skids or jackknifes

Nothing in particular

Longer stopping distances

Wider turns

28 / 30

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

They're not mandatory

Since 1992

Since 2010

Since 2000

29 / 30

When using runaway lanes, which does not apply?

Use the lane before the vehicle is out of control

Use the lane when the brakes no longer control the descent

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

30 / 30

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

With heavy trailer loads

Never
