Causes less interference from loads that overhang the front of the deck

No reason

It's the straightest path

It's the shortest path

5 / 30

The vehicle must return to the yard

6 / 30

How are failures in the supply circuit recognized?

After a post-trip inspection

During brake failure

During pre-trip inspections

The air pressure gauges not replenishing when the air pressure gets below the governor cut-in level

7 / 30

What will cause the glad hand couplers to leak?

If the couplers are not attached securely

If the air pressure is too much

If the seals are the wrong size

If the seals are soft or degraded

8 / 30

During emergency braking, which statement is false?

Monitoring air pressure gauges for proper operation

When safely stopped, the vehicle should not be driven until repairs are completed

Hold a steady brake application to avoid additional loss of air

Pump the brake pedal until air builds up in the lines

9 / 30

If the trailer service brakes are not working and the vehicle must be stopped quickly, what should the driver do?

Apply the mechanical brakes

Take a longer route to stop the vehicle

Pull the trailer air supply valve

Pump the brakes

10 / 30

Is the trailer supply valve part of the tractor's protection system?

Yes

Straight trucks only

Only if towing tandem trailers

11 / 30

What is the only tractor air system failure that will cause a service circuit's brakes not to work during a service application?

Secondary service circuit failure

None of the above

Emergency brake failure

Primary service circuit failure

12 / 30

What's the purpose of the slack adjuster?

It forces the air intake valve

It converts push rod force from the chamber to torque on the s-cam shafts

It automatically adjusts the slack in the brake lines

None of the above

13 / 30

What year did were spring park brakes required on trailers?

1996

1981

1976

1986

14 / 30

Foundation brakes are the mechanical component at the axle ends. If they are not working properly, what happens?

The driver should find a place to come to a safe stop

The driver should apply the park brakes

The driver will need to use the emergency brakes to stop the vehicle

The air brake system will not be able to stop the vehicle

15 / 30

What do glad hand couplers do?

None of the above

Connects the air lines to the cylinders

Connects the air dryer to the air lines

Connects the air lines to the trailer

16 / 30

During a secondary service circuit failure, which brakes will not apply?

The drive axel brakes

The steering axle brakes

All of the brakes

The trailer brakes

17 / 30

What will enforcement officers during Level 1 Commercial Vehicle Safety Alliance (CVSA) inspection will check?

Both parts of the tractor's protection system

The couplers

The psi of the primary tank

The psi of the secondary tank

18 / 30

What can become a problem of a tractor using coiled plastic air lines?

Nothing

They become brittle over time

They become tough to attach to the trailers

They are often too short and will stretch, causing the lines to shrink in diameter

19 / 30

What does the tractor protection valve do?

Closes off the service line

Controls the supply line

Stops air pressure from entering the lines

Uses supply line pressure to open the service line

20 / 30

What can you do to remove contamination before attaching the glad hand couplers?

Nothing

A quick discharge of air pressure before connecting the glad hand couplers to blow contamination out

Blow into the couplers

Shake the couplers for 10 seconds each before connecting the glad hand couplers to shake the contamination out

21 / 30

What is the minimum lining thickness for brake linings from the Commercial Vehicle Safety Alliance (CVSA) roadside inspection out-of-service criteria?

3/4 inch (19 mm)

1/4 inch (7 mm)

1/2 inch (13 mm)

3/8 inch (9.5 mm)

22 / 30

What should glad hand couplers have on them when not pulling a trailer?

None of the above

Dead-end couplers

Semi-automatic couplers

Full-automatic couplers

23 / 30

If there is any sign that the trailer service brakes are not working and the vehicle must be stopped quickly, what should the driver do?

Pump the pedal

Pull the trailer supply valve

Apply the park brakes

Downshift

24 / 30

When would the dash park control valve be used?

Poor road conditions

Parking on a grade

Any situation where there is a loss of service brakes and a quick stop is required

Overnight parking

25 / 30

What do the air lines that connect to the trailer carry?

Most of the air supply

The air supply and the brake signal to the trailer service and park circuits

Hydraulic fluid

All of the air supply only

26 / 30

Rather than using mechanical spring park brakes to hold the foundation brakes on for the emergency brake, what can be done instead?

Nothing can be done

Air from the service tank is supplied to the service chambers

Increase the size of the brake pads

Increase the diameter of the air hoses

27 / 30

Having a very powerful emergency brake, twice as powerful as spring park brakes, what is the risk?

Brake lockup in an emergency application

Brake failure on the trailers

Brake failure on the tractor

Having a load shift in an emergency

28 / 30

What does the service/control line do?

Carries the control system from the foot valve to the trailer service circuit relays

Blocks the control system

None of the above

Disconnects the trailer service relays

29 / 30

Pushing in the trailer air supply valve (red button) with the park control valve (yellow button) pulled during these vehicle inspections will allow what to happen?

The driver will know if lines were crossed

Any air leaks to be noticed and dealt with before the equipment is put into service

The primary tank is low in air pressure

The secondary tank is low in air pressure

30 / 30

What is the problem with air pressure park brakes?

Not enough pressure to park

None of the above

They are not as tight as spring brakes

Air pressure drains out of the system, the park brakes will release
