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. A pre-trip inspection should include:
A check of the engine oil level.
Removing coolant.
Washing the tire rims.

When examining the engine compartment during a pre-trip inspection, you should check the engine oil level, the radiator coolant level, and the condition of the hoses.

2. What is road rage?
Operating a motor vehicle with the intent of doing harm to others
Operating a motor vehicle that is deemed unsafe
Operating a motor vehicle that has not been inspected

Aggressive driving is defined as operating a motor vehicle in a selfish, bold, or pushy manner. Road rage is defined as operating a motor vehicle with the intent of doing harm to others, or the intent of physically assaulting another driver or their vehicle.

3. After completing a pre-trip inspection, you should ensure that the:
Service line valve is closed.
Trailer hand brake is applied.
Emergency line valve is open.

Before a trip, you should ensure that air reaches all air brakes on all trailers by opening up the rear emergency line and service line shut-off valves and listening for escaping air. Close both shut-off valves before beginning to drive.

4. Radial and bias-ply tires:
Should be used together.
Should be used together on the front of a vehicle.
Should not be used together.

Radial and bias-ply tires should not be used together. All wheels on a vehicle should be the same style and equally-sized.

5. Liquid surge occurs in:
Overfilled tanks.
Partially-filled tanks.
Tanks that have not been used for a period of time.

Surge results from the movement of liquid in tanks that are partially filled.

6. If you use the trailer hand brake while your trailer is skidding, it will:
Stop the skid.
Straighten the trailer.
Continue the skid.

If you are experiencing a trailer jackknife, you can help your tires regain traction by releasing the brakes. Using a trailer hand brake while experiencing a skid will only cause the skid to continue.

7. When near a railroad crossing:
You should expect to hear every approaching train.
You may not hear a train, even if one is approaching.
You will hear two short blasts of a train's horn if a train is approaching.

You should never assume that you will hear an approaching train. The train operator may fail to sound the horn, or the use of a train's horn may be prohibited in a specific area. Even if the train does sound its horn, noise from inside your own vehicle may prevent you from hearing the train until it is dangerously close.

8. Having anti-lock brakes on only one axle:
Will not make a difference in braking.
Will provide increased control in braking.
Will likely cause the air brakes to malfunction.

If a vehicle has anti-lock brakes on just one axle, the driver will still have more control during braking than they would without any anti-lock brakes.

9. Parked delivery trucks may be hazardous because:
The trucks are often shiny.
People are often in a hurry when exiting such trucks and may not look for other vehicles.
Packages often fall out of the trucks and into the road.

Passing parked delivery or postal trucks can be dangerous because the driver may be in a hurry and pull into traffic without warning, or may they suddenly step out of the vehicle without checking for other traffic.

10. Hydroplaning usually occurs:
When tires are properly inflated.
When driving at speeds slower than 15 mph.
In areas where water collects on the road.

Hydroplaning occurs on surfaces where water has collected. If there is enough water, vehicles can hydroplane at speeds as low as 30 mph. Hydroplaning becomes more likely if tires are under-inflated or if the tread is worn.

11. How much space should be between the upper and lower fifth wheel?
About five inches of space
A maximum of two inches of space
No space

Before a trip, be sure to inspect all couplings. There should be no space between the upper and lower fifth wheel.

12. A highway curve should be taken:
At or slightly above the posted speed limit.
At the posted speed limit.
Well below the posted speed limit.

Due to a high center of gravity, tank vehicles are especially prone to tipping over in turns and curves. To counteract this, you should take curves and ramps at speeds that are well below the posted limits.

13. The power unit of a placarded vehicle must carry a fire extinguisher with a minimum rating of:
10 B:C.
30 B:C.
40 B:C.

The power unit of a placarded vehicle must be equipped with a fire extinguisher with an Underwriters Laboratories (UL) rating of 10 B:C or more.

14. A fatigued driver:
Is usually extra alert.
Is usually more conscientious than a typical driver.
May be slower to make critical decisions than a typical driver.

Fatigued drivers are slower to see or react to hazards than drivers who are not fatigued. Drivers are impaired in their ability to make critical decisions when they are driving drowsy.

15. If you notice a cargo leak, you should identify the leaking hazardous materials by:
Smelling the materials.
Touching the materials.
Using the shipping papers.

If you discover a cargo leak while transporting hazardous materials, use the shipping papers, label, or package location to identify which materials are involved. Do not try to touch or smell the leaking materials to determine what they are because doing so could result in injury or death.

16. Watching the road ahead of you:
Allows you time to make a plan to avoid an upcoming hazard.
Is not encouraged as it distracts you from driving.
Is only important when traveling in congested traffic.

Always watch for hazards on the road ahead. Doing this will allow you time to react to hazards before meeting them.

17. When Division 1.3 materials are being transported, the floor liner should be:
Made from non-ferrous materials.
Attached loosely.

You should use a floor lining when transporting Division 1.1, 1.2, or 1.3 materials. The floors must be tight and the liner must be made from either non-metallic material or non-ferrous metal. Non-ferrous metals are any metals that do not contain iron or iron alloys.

18. When coming to a stop, you should apply the brake pedal by:
Pushing down gradually.
Pushing down quickly.
Pulling up gradually.

When stopping, you should push the brake pedal down gradually. Braking gradually will help you to maintain proper control of your vehicle.

19. The "crack-the-whip" effect can:
Turn over a trailer.
Be more effective than braking.
Make a truck move faster.

Trailers can overturn as a result of the "crack-the-whip" effect. The last trailer in a combination is the most prone to tip over due to this effect. Drivers should be aware of the rearward amplification of their specific vehicles and drive accordingly.

20. The best way to recognize that your trailer has started to skid is by:
Seeing other drivers' faces.
Checking the trailer in your mirrors.
Feeling the trailer move.

The easiest way to become aware that your trailer has begun to jackknife is to observe it in your mirrors. Checking your trailer in your mirrors will also allow you to spot any skidding at the earliest possible moment.
