Not enough to pass :-(

Ouch! While you were on a roll there for a few questions, you didn’t pass this time. But I know this test, and I think you’ll pass next time. Really.

1. If a vehicle is found to be over-length during a pre-trip inspection, the driver should:

Trim the length of the load.

Ask someone else to drive.

Ensure flags and lights indicating the oversize load are fastened securely.

Drive without making any changes.

If a pre-trip inspection reveals a load to be oversize, the driver must confirm that all required signs, flags, lamps, and reflectors are safely and properly mounted, and that and all required permits are in their possession.

2. A skid caused by acceleration can likely be solved by:

Removing your foot from the accelerator.

Braking.

Swerving to the right.

Swerving to the left.

Skids caused by acceleration frequently occur on slippery road surfaces. These skids can generally be resolved by the driver removing their foot from the accelerator.

3. The easiest way to recognize that your trailer has begun to skid is to:

Ask another driver.

Use your mirrors to determine if the trailer has left the lane.

Release the brake pedal and then push it down again.

Watch the jackknife warning light on the control panel.

The easiest way to spot a trailer skid is to use your mirrors. Any time you brake hard, check your mirrors to ensure that your trailer is still in its proper position.

4. Trailers built before 1975 are:

Required to have spring brakes.

Not required to have spring brakes.

Unsafe to drive.

Prohibited from public roadways.

Trailers built before 1975 are not required to have spring brakes. When parking a trailer without spring brakes, be sure to use wheel chocks to prevent the trailer from rolling.

5. While driving, if it is discovered a vehicle's ABS is not working, the driver should:

Put on their hazard lights.

Downshift.

Brake normally.

Use their parking brake to stop.

If an Anti-Lock Braking System (ABS) is not working, the vehicle's basic braking functions are still intact. The driver should continue to drive and brake in a normal fashion.

6. To drive safely, it is important to remember:

How much distance your vehicle needs to stop.

Possible shortcuts along your planned route.

That arriving to your destination on time is the most important thing.

That other drivers will move out of your way when you are merging with traffic.

To drive safely, it is important to remember how much distance your vehicle will need to stop. Stopping distance for a vehicle can change with road conditions, weather conditions, and the quality of cargo in the vehicle's tanks.

7. Drivers are usually the least alert:

In the morning.

In the early evening.

Late at night.

In the afternoon.

Drivers are usually less alert when driving at night, especially after midnight.

8. Sometimes, when checking the automatic transmission fluid level:

Your vehicle should be parked uphill.

Your vehicle should be parked downhill.

Your vehicle should be washed.

Your vehicle may have to be left running.

In some vehicles, you may have to leave the engine running to check the automatic transmission fluid level.

9. Using the trailer hand valve while driving:

Will help you turn safely.

Will stop your trailer safely.

Can cause a skid.

Is impossible.

Never use the trailer hand valve while operating your vehicle. Using the trailer hand valve while driving can cause your trailer to skid.

10. When loading liquid cargo, you should take into account:

The weight of the liquid.

The color of the cargo.

The air pressure in the tires.

The speed limits on the route.

Factors that affect how much liquid is safe to load into your tank include how much the liquid will expand in transit, the weight of the liquid, and legal weight limits.

11. If an approaching driver is using their high beam headlights, you should:

Look directly at the headlights.

Flash your high beam lights to remind the driver to switch to their low beams.

Look to the right side of your lane until the vehicle has passed.

Pull to the side of the road until the vehicle has passed.

If a vehicle is coming toward you while using its high beam headlights, glance away from the headlights and toward the right side of the road until the vehicle has passed. This will keep you from being blinded by the lights.

12. If colors are being used to distinguish glad hands, which color is used for service lines?

Orange

Yellow

Green

Blue

When trailer air lines are color-coded, the service lines are generally blue and the emergency lines are generally red.

13. If the spring brakes are activated, you should never:

Push down the brake pedal.

Open the hood.

Release air from the air storage tanks.

Open the door to the cab.

Never apply the brake pedal if your spring breaks are activated. Brakes can be damaged if they are subject to both springs and air pressure.

14. All air tanks must include:

A drain valve.

A lock.

A trap door.

A warning sticker.

Air brake system tanks must contain drain valves. These valves are used to drain accumulated oil and water from the tanks and may be either manually or automatically operated.

15. When covering cargo, a cover that flaps in transit:

Is acceptable.

Allows air to get to the cargo to keep it cool.

Can tear away.

Can attract birds.

If cargo is covered, the cover should not flap in the wind in transit. The cover could tear loose, uncovering the cargo while potentially blocking your view or the view of others.

16. When loading a trailer, it is important to:

Place as little weight as possible over the axles.

Place an appropriate amount of weight over the axles.

Not be concerned about how the weight is distributed.

Only place weight over the axles.

The weight of cargo in a trailer should be evenly balanced. Having too much or too little weight on an axle can interfere with proper control of the vehicle. Additionally, having too much weight on one axle can damage it.

17. During an applied leakage test, the maximum leakage rate for a triple combination vehicle is:

10 psi in a minute.

8 psi in a minute.

6 psi in a minute.

4 psi in a minute.

It is important to know the maximum air loss rate that is safe for your specific vehicle. A triple combination should have a leakage rate no higher than 6 psi in a minute during an applied leakage test.

18. If transporting a package that contains radioactive materials, it is important to know that:

Radiation will pass through to other packages.

The packages should be carried in the cab.

The packages should be loaded on their side.

You cannot use bridges.

Radiation surrounds packages of radioactive materials and passes through to other nearby packages. To address this, the number of radioactive packages that can be loaded together is limited.

19. When driving:

It is best to hide your intentions from others.

You should only use turn signals if there are vehicles near you.

You should not use turn signals in construction zones.

You should always use turn signals to warn others about your intentions.

Rely on your taillights.

Sound your horn.
