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. Which of the following determines your blood alcohol concentration (BAC)?
How much you drink
How frequently you drink
The temperature of the drink

The main factors that determine a person's blood alcohol concentration (BAC) are how much alcohol has been consumed, how quickly it was consumed, and the person's body weight.

2. When leaving your vehicle:
The air brakes should be applied.
The parking brake should be applied.
Brakes should not be applied if the vehicle is left out of gear.

Parking brakes should be used whenever you park. If necessary, chock your wheels.

3. As part of the vehicle inspection test, you will be asked to:
Explain what you would inspect and why.
Replace an electrical fuse.
Unload the trailer.

During the vehicle inspection test, you will be required to do a complete inspection of your vehicle. During this inspection, you must explain to the examiner what you are inspecting and why you are inspecting those items.

4. A trailer that is too high:
May not couple correctly.
Will couple securely.
Is not an issue.

Before coupling together a tractor and a trailer, you should make sure the trailer is at the proper height. If the trailer is too low, the trailer nose may be damaged. If the trailer is too high, it may not be able to couple correctly.

5. To use the stab braking method while transporting liquid cargo, you should apply the brakes:
With about half of your usual force.
As hard as possible without locking the wheels.
Completely until the wheels lock up. Release the brakes until the wheels start rolling, then repeat the process.

The stab braking method for emergency stops involves fully applying the brakes until they lock up. The brakes are then released until the wheels start rolling, and then the process is repeated.

6. When trying to put out an electrical fire, you should:
Use water.
Use a B:C extinguisher.
Use an X extinguisher.

B:C fire extinguishers are designed to work on electrical fires and burning liquids. Don't pour water on an electrical fire.

7. When driving in winter, which of the following should receive extra attention in a pre-trip inspection?
Coolant and antifreeze levels
The air conditioning unit
The oil pressure

When doing a pre-trip inspection during the winter, you should pay extra attention to the coolant level and amount of antifreeze; the defrosting and heating equipment; the wiper blades and windshield washer; the tires and tire chains; the lights and reflectors; the windows and mirrors; the hand holds, steps, and deck plates; the radiator shuttles and winterfront; and exhaust system.

8. Before a trip, you can make sure air flows to all trailers by:
Checking for moving air inside of each trailer.
Listening for air at the rear shut-off valve.
Feeling for air at the front shut-off valve.

Before a trip, ensure that air in the air brake system reaches all trailers. Do this by waiting for air pressure to build, then sending air to both the emergency and service lines and opening the shut-off valves on the rear of the last trailer. If air escapes from the shut-off valves in the rear of the combination, the air is being supplied to the entire vehicle.

9. If you are confronted with an aggressive driver, you should:
Make eye contact.
Try to stay in their way.
Ignore any hand gestures.

The best thing to do when confronted with an aggressive driver is to get out of their way, if possible. Avoid making eye contact, which could further provoke the driver. Ignore any hand gestures made by the driver.

10. Shippers package in order to ____ hazardous materials.

Shippers package hazardous materials in a way that is meant to completely contain the materials. Vehicles should be placarded to communicate the risk of the cargo.

11. Which of the following should not be a factor in determining the quantity of liquid to load into a tank?
The degree to which the liquid will expand in transit
The weight of the liquid
The speed of the driver

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, legal weight limits, and the temperature of the load.

12. When in heavy traffic, the safest driving speed is:
Slower than the speed being driven by surrounding traffic.
The same speed being driven by surrounding traffic.
Faster than the speed being driven by surrounding traffic.

In heavy traffic, it is safest to travel at the same speed as other vehicles. If two vehicles continue to drive in the same direction at the same speed, they cannot hit each other.

13. One way to prevent hydroplaning on wet road surfaces is to:
Ensure that your tires have good tread depth.
Under-inflate your tires.
Drive faster than usual.

When driving on a wet road surface, the risk of hydroplaning is increased if your tire pressure is too low or your tire tread is too worn. If you begin to hydroplane, release the accelerator and push in the clutch to slow down.

14. Antifreeze helps to keep an engine functioning properly:
But only if it is cold outside.
To be more fuel efficient.
Both when it is cold and hot outside.

It is always important to have enough water and antifreeze in a vehicle's cooling system. Despite the name, antifreeze is beneficial to an engine even in hot weather.

15. ____ is an example of required emergency equipment.
A spare electrical fuse
A loud horn
A battery-operated flashlight

All commercial motor vehicles are required to be equipped with the proper emergency equipment. This may include spare electrical fuses; three red reflective triangles, six fuses, or three liquid burning flares; and at least one properly charged and rated fire extinguisher.

16. If you are transporting hazardous materials and the cargo is on fire, you should:
Try to put it out with a fire extinguisher.
Contact emergency personnel and let them battle the fire.
Hope the fire goes out by itself.

Fighting a hazardous materials fire requires special training and protective gear. Unless you have the proper equipment and training, do not try to fight a hazardous materials fire yourself.

17. Driving at night is:
Safer than driving during the day.
Just as safe as driving during the day.
More dangerous than driving during the day.

Driving at night is more dangerous than driving during the day because hazards become more difficult to see in the dark.

18. Rough acceleration:
Is a good way to stay awake on long trips.
Is distracting.
Can cause mechanical damage.

Rough acceleration can cause mechanical damage, so be sure to accelerate smoothly and gradually.

19. A distracted driver:
Usually follows the rules of the road.
Usually has slowed perception.
Is a good person to follow.

Distracted drivers perceive hazards on the road more slowly than drivers who are focused, or they do not perceive hazards at all.

20. Too much air pressure in a tire:
Is not possible.
Is encouraged on long drives.
Can be dangerous.

Tires should never have too much air pressure. Be sure to check your tires' air pressure with a gauge during inspections.
