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 you must drive in reverse, using driver's side backing:
Is always encouraged.
Is discouraged.
Is only recommended if it is raining.

If you must back up, it is safest to back toward the driver's side of the vehicle. This way, as the driver, you will have the best possible view of your path of travel.

2. When you must travel down a hill, when should you switch into a lower gear?
As you begin to move downward
As you go downhill and pick up speed
Before you start going downhill

You should always slow down and shift into a lower gear before starting down a hill. If you do not begin to drive down a hill at a low enough speed, you risk overusing your brakes, causing them to overheat and fade.

3. What is a retarder?
A device that prevents a vehicle from going too fast
A device that prevents a vehicle from being too loud
A device that improves a vehicle's gas mileage

Retarders help to slow vehicles, reducing drivers' need to use brakes.

4. When drivers turn, they usually:
Look in the direction of the turn.
Look in the direction opposite the turn.
Look behind their vehicles.

When turning, drivers usually look in the direction of their turn. If a driver fails to signal before a turn or lane change, their body movements may still provide a clue that they are planning to turn.

5. When encountering a railroad crossing during the driving test, you should:
Pass another vehicle on the tracks if the other vehicle is moving too slowly.
Change lanes while on the tracks.
Not change gears while on the tracks.

During the on-road driving test, you must not stop, change gears, pass another vehicle, or change lanes while any part of your vehicle is in a railroad crossing.

6. A wig wag is:
A low pressure warning device.
A tube that carries air to the brakes.
A type of air brake system.

Vehicles with air brakes are required to be equipped with a low pressure warning device. A wig wag is a type of low air pressure warning device. This device drops a mechanical arm into the driver's view if the pressure in the tanks drops to a level between 55 and 75 psi.

7. When entering a curve, you should:
Shift into neutral.
Use the shoulder.

You should always slow down to a safe speed and shift into a lower gear before entering a curve.

8. When stopping in an emergency situation, you should:
Veer your trailer to the right and stop.
Stop in a straight line.
Veer your trailer to the left and stop.

If you need to make an emergency stop, you can use either the controlled braking method or the stab braking method. It's important to brake in a way that keeps your vehicle in a straight line but will still allow you to turn if necessary.

9. When performing a pre-trip inspection and looking into the fifth wheel gap, you should:
Make sure the locking jaws are open.
Make sure the locking jaws are fully closed around the kingpin.
Make sure the locking jaws are loose.

When inspecting a trailer coupling, you should make sure the fifth wheel locking jaws are closed around the shank of the kingpin, not the head of the kingpin.

10. A driver should ensure that:
The truck is overloaded.
The truck is properly loaded.
The cargo is mostly in the front of the trailer.

It is essential to the safe operation of a CMV that cargo be properly loaded. Improper loading can affect handling and damage the vehicle. Additionally, improperly loaded materials can cause injury or death by falling off of the vehicle.

11. During the driving test, the examiner will be scoring you on:
How well-spoken you are.
How quickly you arrive to your destination.
General driving behavior.

During the on-road driving test, the examiner will be score you on specific driving maneuvers as well as on your general driving behavior. You must drive in a safe and responsible manner; obey all traffic signs, signals, and laws; and not cause an accident or commit a moving violation.

12. If driving through flowing water or a large puddle, you should:
Increase your speed.
Gently apply the brakes.
Try to stop in the water.

It is best to avoid driving through large puddles or moving water. If there is no way to avoid driving through water, you should slow down, shift into a low gear, and gently apply the brakes. Pressing linings against the brake drums or discs will keep water, mud, silt, and sand from getting inside the brake mechanisms.

13. In order to receive a hazardous materials endorsement, a person must complete all of the following, except:
A HazMat knowledge test.
An FBI fingerprint check.
A CIA intelligence check.

To obtain a hazardous materials endorsement, you must pass the HazMat knowledge test; undergo a Federal Security Threat Assessment; provide proof of U.S. citizenship or permanent residency; and undergo an FBI fingerprint check and federal criminal history background check.

14. On flat surfaces, wheel chocks:
Can be used to prevent a parked vehicle from moving.
Make it easier for a parked vehicle to roll.
Should only be used on the front driver's side tire.

In situations where a driver cannot use a parking brake, wheel chocks can be used to hold a parked vehicle in place on a level surface.

15. Hanging meat as cargo is usually:
Easy to transport.
Dangerous, due to the possible scent.

An operator should drive with care when transporting a cargo of hanging meat. Such a load is unstable, both because it has a high center of gravity and because the swinging of the meat can affect the driver's handling of the vehicle.

16. A cracked rim should be:

You should drive past the parking space before backing into it while bringing the rear of your vehicle as close to the rear of the space as possible. Your vehicle should be completely within the boundaries of the space.

22. Which of the following is an indication of standing water on the roadway?
Tire splashes
Portions of the pavement that are dry
Leaves on the road

Hydroplaning can occur in places where water collects on the road. Clear reflections, tire splashes, or rain drops on the road can indicate the presence of standing water.

23. To make it easier to leave a parked position, you should park:
In a way that allows you to back up when exiting.
