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 driving, it is important that you:
Develop plans to get out of potentially dangerous situations.
Enjoy the scenery.
Turn your head all the way around rather than use mirrors.

When driving, you should continually scan the road for possible hazards. Form plans about what you will do if the hazards develop into emergencies.

2. When pulled off on the side of the road:
A driver should keep the driver’s side door open.
A driver should turn on the emergency flashers.
The driver should wave their arms.

If you must stop on the side of the road, make sure to use your four-way emergency flashers. This is particularly important at night.

3. Antifreeze helps to keep an engine functioning properly:
But only in cold weather.
But only in hot weather.
Regardless of the weather.
While minimizing the vehicle's fuel use.

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.

4. You should maintain at least ____ of following distance per every 10 feet of your vehicle when you are traveling more slowly than 40 mph.
One second
Two seconds
Three seconds

At speeds below 40 mph, you should allow at least one second of following distance for every 10 feet of your vehicle. Follow the same formula when traveling at faster speeds, then add one additional second to your following distance. Remember that larger vehicles require more space to stop than smaller vehicles.

5. 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.

6. A sign indicating a maximum safe speed:
Is suggesting a driving speed, but vehicles may travel faster than the posted speed.
Is suggesting a speed limit to be followed only by vehicles weighing more than 26,000 pounds.
Should be followed and no vehicle should travel faster than the posted speed.
Is only applicable to automobiles.

You should never exceed the speed shown on a "Maximum Safe Speed" sign.

7. While operating on a downgrade, you should brake until you reach a speed that is:
5 mph below your safe speed.
10 mph below your safe speed.
15 mph below your safe speed.

While driving downhill, you should hold down the brake pedal until your vehicle reaches a speed 5 mph below your safe speed, then release the brake pedal. Repeat this process.

8. A pre-trip vehicle inspection:
Is not required if the driver regularly uses the vehicle.
Is not required for trips under 100 miles.
Is only to be performed by a mechanic.
Is required by law.

Drivers are required by state and federal law to inspect their vehicles before beginning to drive.

9. If the coolant temperature gauge goes above the highest safe temperature, you should:
Continue to drive.
Pull over and figure out what's wrong.
Run the air conditioner.

If the coolant temperature gauge goes above the highest safe temperature, you should stop driving as soon as possible and try to figure out what is wrong. There could be an issue in your vehicle that could lead to engine failure and possibly a fire.

10. Looking far ahead of your vehicle while driving is:
Discouraged, as there is little you can do about something far up the road.
Encouraged to help you identify hazards as early as possible.
Not permitted.

Good drivers look down the road at least 12 to 15 seconds ahead of their vehicles. This makes it possible to identify hazards early, when drivers are more likely to have time to respond appropriately.

11. Why should your mirrors be adjusted to show the road behind you as well as part of your vehicle?
Having only the road in the mirrors would likely make the driver carsick.
Having part of the truck in the mirrors serves as a point of reference.
It is illegal to have only the road in the mirrors.
The driver should be able to see the reflection of surrounding vehicles on the trailer.

Part of your vehicle should be visible in your mirrors so that you have a point of reference when judging how close other drivers and objects are to your vehicle.

12. When traction is poor, a driver should accelerate slowly:
Because it is best to always accelerate very slowly.
So they do not lose control of their vehicle.
So the driver does not accelerate faster than the vehicle ahead.
To be the last vehicle through an intersection.

Speeding up too quickly on a road with poor traction could cause a driver to lose control of their vehicle. In conditions that cause poor traction, a driver should accelerate especially smoothly and gradually.

13. Which of the following indicates drowsy driving?
Eyes going out of focus by themselves
Having trouble keeping your head up
Drifting from lane to lane
All of the above

Indicators of drowsiness while driving include your eyes closing or going out of focus by themselves, having trouble keeping your head up, and drifting between lanes.

14. Drivers talking to passengers in their vehicle should be viewed as:
Responsible drivers.
Distracted drivers.
Knowledgeable drivers.

Drivers who are engaged in conversation with passengers may be distracted from the task of driving. Use extra caution when driving near distracted drivers.

15. Which of the following is not a type of tie-down equipment?

You must use the proper number of tie-downs when securing cargo on a flatbed trailer. Examples of tie-down equipment includes ropes, straps, and chains.

16. When starting a vehicle, warning lights and buzzers:
Should not light up or sound.
Should turn on and shut off quickly.
Should turn on and remain on.

After starting a vehicle's engine, the warning lights and buzzers should turn on, then quickly turn off.

17. Once the air tanks are at an air pressure level of 125 psi, the air compressor governor will:
Stop the compressor from pumping air.
Release air from the tanks.
Begin pumping air into the tanks.

An air compressor governor will stop the compressor from pumping air once the air tanks are at an air pressure level around 125 psi. This air pressure level is referred to as the "cut-out" level.

18. If an approaching driver is using their high beam headlights, you should:
Look directly at the headlights.
Flash your high beam lights to remind the driver to switch to their low beams.
Look to the right side of your lane until the vehicle has passed.
Pull to the side of the road until the vehicle has passed.

If a vehicle is coming toward you while using its high beam headlights, glance away from the headlights and toward the right side of the road until the vehicle has passed. This will keep you from being blinded by the lights.

19. During the driving test, when encountering a railroad crossing, you should:
Pass another vehicle on the tracks if the other vehicle is going too slow.
Get out of the vehicle to check for a train.
Not change gears while your vehicle is on the tracks.

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

20. Hanging meat in a refrigerated truck:
Is a good way for inexperienced drivers to gain experience.
Requires a skilled driver.
Is illegal in most states.

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.

21. During an applied leakage test, what is the maximum leakage rate that is safe for a single vehicle with air brakes?
10 psi in one minute
5 psi in one minute
3 psi in one minute

It is important to know the maximum air loss rate that is safe for your specific vehicle. A single vehicle with air brakes should have a leakage rate no higher than 3 psi in a minute during an applied leakage test.

22. During the pre-trip vehicle inspection test:
Applicants will not have to identify the ABS.
Windshield wipers are not to be addressed.
Shock absorbers only need to be checked on one axle.
The steering box should be checked for leaks.

During the external inspection portion of the pre-trip vehicle inspection test, you must verify that the steering box is securely mounted and not leaking.

23. The air entering air storage tanks may contain:
Water and compressor oil.

The air that enters air storage tanks in an air brake system usually contains a certain amount of water and compressor oil. Because accumulations of these materials can damage the braking system, tanks are equipped with drains to allow their removal.

24. When changing lanes, turn signals:
Should not be used.
Should only be used if a vehicle is close to you.
Should be used each time.

Always signal your intentions before turning or changing lanes. Do not assume that other drivers will move out of your way simply because you are signaling to turn.

25. Which of the following may result in an applicant being denied a hazardous materials endorsement?
They are not a lawful permanent resident of the United States.
They have had a speeding conviction within the previous three years.
They did not correctly answer every question on the written hazardous materials endorsement test.
They did not pass the written hazardous materials endorsement test on the first attempt.

You will be denied a hazardous materials endorsement, or lose an existing endorsement, if you renounce your U.S. citizenship; are not a lawful permanent U.S. resident; are wanted for, indicted for, or convicted of certain felonies; are judged mentally defective or are committed to a mental institution; or are deemed by the Transportation Security Administration (TSA) to pose a security threat.

26. If one-fourth of the leaves in a leaf spring are missing when a vehicle is inspected:
The vehicle’s driver will be allowed to drive, but only at reduced speeds.
The vehicle will be put out-of-service until it is fixed.
The vehicle will be fine to drive since most of the spring is in place.

When inspecting a vehicle's suspension, you should look for broken or missing leaves in the leaf springs. Any defect of this kind is dangerous. If one-fourth or more of the leaves are missing from any leaf spring, the vehicle must be put out-of-service.

27. When adjusting your mirrors before a trip:
No part of your vehicle should be visible in any mirror.
Part of your vehicle should be visible in the mirrors.
More than half of each mirror should show the vehicle.

When properly adjusted, your mirrors should each display some part of your vehicle. Being able to see your own vehicle in your mirrors will give you a point of reference when judging the positions of other objects.

28. A CMV should:
Not have a fire extinguisher, unless it is being used to transport hazardous materials.
Not have a fire extinguisher, unless it will be traveling through remote areas.
Have a fire extinguisher and other emergency equipment.

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.

29. When driving, the steering wheel should be:
Held with one hand.
Held with both hands on opposite sides of the wheel.
Held with both hands at the bottom of the wheel.
Held with both hands at the top of the wheel.

Hold the steering wheel firmly with both hands, placing them on opposite sides of the wheel.

30. Front brake limiting valves were intended to:
Prevent the front tires from skidding.
Prevent the front tires from overheating.
Create equal brake usage.
Remove uncertainty when applying the brakes.

Some older vehicles with air brakes have front brake limiting valves. These valves were intended to reduce the risk of front wheels skidding. However, research has shown that such devices are unnecessary, so they should be left in the "normal" position.

31. What tells you how much pressure is in your vehicle's air tanks?
The supply pressure gauge
The ABS malfunction lamp
The tractor protection valve

A vehicle that is equipped with air brakes must also be equipped with a supply pressure gauge. This gauge tells the driver how much air pressure is in each of the vehicle's air tanks.

32. In a dual air brake system, air pressure should build from 85 to 100 psi within ____ seconds.

When inspecting a vehicle with a dual air brake system, you should wait for air pressure to build from 85 to 100 psi in both the primary and secondary systems. This should take about 45 seconds.

33. When entering a foggy area, you should:
Stop on the side of the roadway.
Pass other vehicles.
Slow down.
Use your high beam headlights.

Always slow down before entering a foggy area. Use low beam headlights, avoid passing others, and avoid stopping on the side of the roadway. It is safest to completely avoid driving under foggy conditions, if possible.

34. If you are being tailgated while driving a large vehicle, do all of the following, except:
Reduce your speed gradually.
Increase your following distance.
Increase your speed.

If you find yourself being tailgated by another driver, you should increase your following distance and avoid making quick moves. Increasing your speed may only result in the other driver continuing to tailgate you at a higher speed. Do not turn on your taillights or flash your brake lights at the other driver.

35. When a construction worker is close to the road, you should:
Increase your speed.
Decrease your speed.
Not drive in any lane.
Wait to proceed until the construction is complete.

In construction zones, do not exceed the posted safe sped limit. Slow down even more when workers are near the roadway.
