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 realize you may be running late to your destination, you should:
Speed up.
Get upset.
Deal with it and drive at a safe speed.

To reduce the risk of developing aggressive driving behavior, you should take measures to manage your stress. One strategy to do this is to simply take a deep breath and accept your circumstances if you realize you will be late to your destination.

2. The trailer hand valve:
Should always be used for parking.
Should only be used for parking on a downgrade.
Should never be used for parking.

Never use the trailer hand valve while parking because doing so may release the air pressure from the braking system, releasing the brakes that are holding the vehicle in place. Instead, use the parking brake or wheel chocks.

3. You will often have to drive your vehicle under bridges and overpasses. If approaching such an opening, you should:
Assume the posted clearance height is accurate.
Assume the posted clearance height is inaccurate.
Measure the height of the opening before proceeding.

Do not assume that posted height clearances are accurate. If the road was repaved after the sign was posted, or if there is packed snow on the ground, the actual height of the opening may be different than what is indicated. If you are not confident that your vehicle will be able to safely clear an upcoming bridge or overpass, you should slow down and find another path, if possible.

4. Load hazardous materials:
Near heat sources.
Away from heat sources.
Away from shadows.

Always load hazardous materials away from heat sources. Be aware of regulations on explosive or flammable materials that prohibit them from being loaded in cargo spaces with heaters.

5. What is the average driver’s reaction time?
1/16 of a second
1/8 of a second
3/4 of a second

The average driver has a reaction time between three-quarters of a second and one second. At 55 mph, this corresponds to a distance of 61 feet traveled.

6. How much water must be present for a vehicle to hydroplane?
Usually several inches
A good amount, such as a large puddle
A small amount

Hydroplaning is an effect in which a vehicle's tires lose traction with the surface of the road and instead glide along a layer of water. There does not have to be much water on the road for this to occur.

7. In hot weather, spots on the pavement where tar is bleeding:
Are very slippery.
Offer the same amount of traction as the rest of the roadway.
Offer more traction than the rest of the roadway.

Tar in road pavement often rises to the surface of the road, or "bleeds," in very hot weather. Watch for such areas because they can be very slippery.

8. Heights posted at bridges:
Are always accurate.
Are legally binding.
Can be incorrect.

Never assume that the posted height on a bridge or other overhead object is correct. Even if it was accurate when posted, things may have changed that affect clearance, either permanently (such as a repaving of the road) or temporarily (such as packed snow on the road).

9. Hydroplaning:
Rarely occurs with large trucks.
Usually happens when vehicles are traveling faster than 65 mph.
Can occur with a minimal amount of water on the roadway.

Hydroplaning is an effect in which a vehicle's tires lose traction with the surface of the road and instead glide along a layer of water. There does not have to be a large amount of water on the road for this to occur.

10. What eliminates alcohol from the bloodstream?
Coffee
Exercise
Time

The body processes alcohol at a fixed rate that cannot be sped up through tricks like drinking coffee. The only way to sober up is to give the body the time it needs to remove the alcohol on its own.

11. Rough acceleration:
Is recommended.
Can cause mechanical damage.
Is required on slippery surfaces.

Always speed up smoothly and gradually so that your vehicle does not jerk. Rough acceleration can cause mechanical damage.

12. When backing up your tractor while coupling it to a trailer, the trailer brakes should be:
Deactivated.
Locked.
Unlocked.

Correctly following the steps to couple and uncouple trailers is vital to safely operating a combination vehicle. Before backing your tractor under the trailer while coupling, make sure your trailer brakes are locked.

13. When backing with a trailer, turning toward the driver’s side is encouraged because:
The driver will have the best possible view.
Power lines should be on the passenger's side.
Other drivers can offer assistance on the passenger's side.

When driving in reverse, it is always recommended that a driver backs their vehicle toward its left side. This will allow the driver the best possible view of the rear of their vehicle.

14. Who must label hazardous materials?
The shipper
The loader
The driver

The shipper of hazardous materials is responsible for packaging, marking, and labeling the materials. They must supply the warning placards.

15. How can a driver maintain alertness while driving?
Stay fit and healthy
Keep the cab warm
Eat heavy foods

Eating heavy foods before driving or keeping the temperature in a cab too high can cause a driver to become drowsy while behind the wheel. Exercising and maintaining a healthy diet will help a driver to stay alert while driving.

16. If confronted by an aggressive driver, you should:
Keep your vehicle in front of them.
Make eye contact with them
Ignore their gestures.

If confronted by an aggressive driver, don't let yourself be provoked by their actions or angry gestures. Do not risk provoking the other driver by making eye contact. Get out of their way if you can do so safely.

17. If driving so slowly that you could impede the flow of traffic, you should:
Drive on the shoulder.
Drive while using your emergency flashers.
Drive without using any lights.

If you must drive so slowly that you will impede the flow of traffic, you should turn on your four-way flashers to alert drivers behind you (as long as local laws allow the use of flashers).

18. When accelerating on a surface with poor traction, such as a wet road, a driver should:
Speed up quickly.
Speed up slowly.
Not be concerned about the pavement.

You should accelerate very gradually when driving under conditions that create poor traction.

19. Before driving a power steering-equipped vehicle, you should make sure that:
The fluid is at a proper level.
The hoses are connected to the battery.
Any leak is small.

When inspecting a vehicle that is equipped with power steering, check the hoses, pumps, and fluid level. In particular, you should look for leaks in the hoses.

20. If a tank is found to be leaking, the driver should:
Drive with their flashers on to warn other motorists.
Get the leak fixed immediately.
Finish the trip and then let someone know.

Transporting liquids or gases in a leaking tank is both unsafe and against the law.
