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. When it’s difficult to see, such as at dawn or dusk, a driver can increase their vehicle's visibility by:
Driving while using their lights.
Driving with their windows open.
Flashing their lights periodically.

When driving at dawn, at dusk, or in inclement weather, you should use your headlights on their low beam setting to increase your visibility.

2. A driver must take the HazMat knowledge test:
Once every year.
Prior to every CDL renewal.
Once every 10 years.
Only once.

You must take and pass the written English version of the HazMat knowledge test and be cleared through a federal background check before every renewal of your CDL.

3. After connecting the air lines to the trailer while coupling, you should:
Supply air to the trailer.
Chock the wheels.
Inspect the fifth wheel.
Connect the electrical cord.

Correctly following the steps to couple and uncouple trailers is vital to safely operating a combination vehicle. After connecting the air lines to the trailer while coupling, you should supply air to the trailer.

4. Place the trailer air supply control in its "emergency" position to test:
The trailer emergency brakes.
A coupling device.
The anti-lock brakes.

Be sure to test the trailer emergency brakes before beginning a trip. After ensuring that the trailer rolls freely, you can test the emergency brakes by pulling out the trailer air supply control, or placing it in the "emergency" position. Pull forward slightly with the tractor and make sure the trailer does not move.

5. If you’re unfamiliar with the area in which you must back up, you should:
Get out of your vehicle and walk around the area to become more familiar with it.
Not use both mirrors, as that can cause too much distraction.
Wait for someone else to back up in the area so you see how they do it.
Turn on your high beam headlights.

Backing is always dangerous because you cannot see everything behind your vehicle. Especially if you are unfamiliar with the area, you should get out of your vehicle and familiarize yourself with your path of travel before beginning to back up.

6. The National Response Center must be notified of an incident resulting in any of the following, except:
Injury requiring hospitalization.
Injury not requiring hospitalization.

The National Response Center must be notified of any incident that results in death; hospitalization; $50,000 or more in estimated property damage; an evacuation of the general public or closure of a major transportation route/facility for more then one hour; fire, breakage, spillage, or suspected contamination involving radiation, bacteria, or toxins. Additionally, if the carrier judges the situation to be so serious that it should be reported, it should be reported.

7. When driving on a wet road, you should reduce your speed by:
About one-half.
About one-third.
About one-quarter.

Reduce your speed when traveling on surfaces that provide reduced traction. Reduce your speed by about one-third when driving on a wet road.

8. What does an Anti-Lock Braking System (ABS) do?
Allow the rear wheels to lock up
Allow all wheels to lock up
Help prevent wheel lockup
Alert other motorists when you are braking

The purpose of an Anti-Lock Braking System (ABS) is to prevent a vehicle's wheels from locking up when the driver brakes hard on a slippery surface.

9. To prevent a rollover, a driver should:
Keep cargo low.
Place cargo high.
Keep cargo loose.
Turn quickly.

Rollovers can happen when a combination vehicle is turned too quickly. To help prevent the risk of rollover, it is important to keep the vehicle's center of gravity low by loading cargo as close to the ground as possible.

10. If you are confronted by an aggressive driver, you should:
Make eye contact.
Ignore their gestures.
Try to race.

If you encounter an aggressive driver, you should not let yourself be provoked by any angry gestures they make toward you. Avoid making eye contact with the other driver and do not try to race them.

11. In a double or triple combination, the ____ trailer should be directly behind the cab.

When positioning trailers in a combination, the most heavily-loaded trailer should be the closest to the tractor. The lightest trailer should be positioned in the rear.

12. A tank usually has:
A low center of gravity.
A high center of gravity.
An extra set of brakes.

Driving tanks requires special care because they usually have high centers of gravity. The driver should also expect cargo movement in transit, if transporting liquid cargo.

13. Which gas would cause concern due to a faulty exhaust system?
Carbon monoxide

A leaking exhaust system can introduce carbon monoxide, which is poisonous, into the cab or sleeper berth.

14. Trailers with low underneath clearance may be difficult to drive:
On interstate highways.
Over railroad crossings.
On dirt roads.
At the posted speed limit.

Railroad-highway crossings may be difficult to cross when pulling a trailer with a low underneath clearance. In particular, both low-slung units and single-axle tractors pulling long trailers are especially challenging to drive over raised crossings.

15. 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.

16. If a vehicle has a vehicle inspection report, the driver:
Should not look at the report and instead try to find any issues themselves.
Should take the vehicle to a mechanic.
Should review the report.
Should not conduct a pre-trip inspection and rely only on the report.

For the first step of a vehicle inspection, you should review the last inspection report on your vehicle, if there is one. The carrier should have repaired any problems noted on the report.

17. When turning quickly to avoid an object in the roadway, you should:
Apply your brakes as you steer.
Give yourself extra clearance by turning more than needed to miss the object.
Turn just enough to miss the object and avoid turning more.
Steer and accelerate at the same time.

When turning quickly to avoid an object, turn only as much as is necessary to clear it. Do not apply the brakes while turning.

18. If you identify hazardous materials leaking while you are driving, you should:
Continue driving to find a phone booth and call the National Response Center.
Park the vehicle.
Leave the area to find help.

If you discover that a cargo of hazardous materials is leaking from your vehicle, you should park the vehicle as soon as possible. The longer you continue driving, the longer the trail of contamination becomes. While this creates potential danger and harm to others, it also increases clean-up expenses.

19. During a trip, landing gear should be:
Completely raised.
Completely lowered.
Skimming the pavement.

Landing gear, or trailer supports, should always be completely raised before a vehicle is driven. Landing gear that is not entirely raised could catch on railroad tracks or other hazards on the roadway.

20. 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.
