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. Which of the following is not an indication of damaged brakes?
Cracked drums
Shoes with oil or grease on them
Shoes worn thinly
Pads free of oil or grease

Potential problems to check for when inspecting brakes include cracked drums; shoes or pads with oil, grease, or brake fluid on them; and shoes that are missing, broken, or worn dangerously thin.

2. Which of the following is not a sign of a person being drowsy?
Frequent blinking
Drifting from your lane
Feeling hungry

Driving drowsy is dangerous and should always be avoided. Warning signs of drowsiness include frequent blinking, your eyes closing or going out of focus by themselves, frequent yawning, and drifting between lanes.

3. Having weight loaded in a way that creates a high center of gravity:
Increases the likelihood of a rollover.
Increases the likelihood that items will fall down.
Increases the difficulty of unloading the cargo.

Transporting cargo that is loaded with a high center of gravity increases the risk that the transporting vehicle will tip over. Cargo should be loaded with a safe weight distribution.

4. During a walk-around inspection, ensure there are no cracks on the brake drums that are more than ____ of the width of the friction area.
One half
One quarter
One third
One tenth

Before beginning a trip, it is important to check the brake drums during your walk-around inspection. It is unsafe to drive if any brake drum has a crack more than one half of the width of the friction area.

5. Texting while driving is worrisome:
Because it creates both mental and physical distractions.
Because a message may be upsetting to the driver.
Because the texts may be more interesting than the task of driving.
Because it is less efficient than a phone call.

When driving, texting is a particularly dangerous distraction because it distracts a driver both mentally and physically.

6. 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.

7. ABS allows you to:
Drive faster.
Brake harder.
Stay in control when stopping.

The function of an Anti-Lock Braking System (ABS) is to help prevent wheel lockup during hard braking. With ABS equipped on your vehicle, you should drive and brake in the same manner that you would without it.

8. Radial and bias-ply tires:
Should be used together on all axles.
Should be used together, but only on the rear axle.
Should not be used together.

When inspecting your vehicle, ensure that radial and bias-ply tires are not being used together.

9. Backing with a trailer is dangerous because:
It is difficult for the driver to see behind the trailer.
There may be extra weight in the front of the vehicle.
Cargo may fall out of the trailer.
Trailers are not made to be driven in reverse.

Backing is always dangerous because it is impossible to see everything that is behind your vehicle. Only drive in reverse if it is absolutely necessary.

10. When approaching a railroad crossing, a driver should:
Rely only on automated signals.
Expect to hear a train.
Cross the tracks before an approaching train reaches the crossing.
Reduce their speed.

You should approach every railroad crossing with the expectation that a train is coming. Do not rely on signals or your hearing to reliably tell you if a train is present. Always slow down when approaching a crossing. Never try to race a train.

11. Blocking is used to:
Prevent cargo from shifting in transit.
Prevent cargo from being loaded too high.
Prevent cargo from being unloaded too quickly.
Prevent cargo from being unloaded easily.

Blocking and bracing are used to prevent cargo from sliding in transit.

12. A distracted driver:
Usually follows the rules of the road.
Usually has slowed perception.
Is a good person to follow.

Distracted drivers perceive hazards on the road more slowly than drivers who are focused, or they do not perceive hazards at all.

13. Passive railroad crossings:
Are controlled by flashing lights.
Are not controlled by any type of traffic control device.
Have gates that lower when trains are approaching.
Should never be crossed by a CMV.

Railroad crossings that are not controlled by any type of traffic control device are known as passive crossings. The decision to proceed across tracks at a passive crossing is entirely up to the driver.

14. Good drivers consistently look ____ seconds ahead of their vehicles.
Two to three
Five to six
12 to 15
30 to 45

Most good drivers consistently look down the road 12 to 15 seconds ahead of their vehicles. Watching ahead of your vehicle will allow you to react to upcoming hazards before meeting them.

15. Which of the following is not a type of distraction?

Distractions that can affect safe driving can be classified as physical (such as reaching for an object), mental (such as talking with passenger), or both (such as talking on a hand-held phone).

16. Friction inside a brake drum is caused when the brake shoes and linings:
Push against each other.
Separate from the axle.
Push against the inside of the drum.
Create excess heat.

Friction inside a brake drum is caused when the brake shoes and linings push against the inside of the drum. The friction in the drums will slow and stop the vehicle.

17. Do not use the parking brake when parking if:
The brakes are very hot.
The brakes are very cold.
There is snow on the ground.
There is water on the ground.

A parking brake should not be used if the vehicle's brakes are very hot from use on a steep downgrade or if the brakes are very wet and temperatures are freezing. Using the parking brake when brakes are hot could cause damage to the brakes, and using the brakes when they are wet in freezing weather may cause the brakes to ice up, rendering the vehicle immobile.

18. Brake fade is a result of:
Brakes being exposed to sunlight.
Brakes being exposed to moisture.
Excessive use of the brakes.

If brakes are overused, they can become too hot. This overheating causes them to fade, making them less effective at slowing the vehicle.

19. Cargo with a high center of gravity:
Can make a vehicle likely to tip over.
Is encouraged in inclement weather.
Is required on some roads.

Cargo with a high center of gravity makes a vehicle more likely to tip over than cargo with a low center of gravity. For this reason, it is important that the weight of cargo be distributed as low as possible.

20. If approaching a railroad crossing that is being approached by a train, you should:
Try to cross the tracks quickly.
Drive around any lowered gates.
Stop and wait for the train to pass before beginning across the tracks.

Never attempt to beat a train to a railroad crossing. It is very difficult to accurately judge the speed of an approaching train. If you come upon a crossing that is being approached by a train, you must stop and wait for the train to pass before you attempt to cross the tracks.

21. What is a drawback of retarders?
They may not be permitted everywhere.
They can help to slow a vehicle.
They cannot be turned off.

A retarder is a device that helps to slow a vehicle, reducing the need for a driver to use the brakes. However, these devices can be noisy and are not permitted everywhere.

22. If stopped on the road or shoulder, within 10 minutes, you must:
Place emergency warning devices.
Alert local law enforcement.
Stand behind your vehicle and motion for traffic to pass you.
Call a mechanic.

If stopped on the side of the road, you must place emergency warning devices, such as reflective warning triangles, within 10 minutes of stopping.

23. When asked to complete a conventional parallel parking maneuver, you should:
Pass the parking space while backing, then pull forward into it.
Pull forward past the parking space, then back into it.
Pull forward into the parking space without passing it first.
Back into the parking space without passing it first.

You may be asked to complete a conventional parallel parking maneuver into a parking space that is to the right of your vehicle. 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.

24. When traction is poor, a driver should accelerate especially slowly:
Because it is always good to accelerate slowly.
To keep from losing control of the vehicle.
To keep from accelerating faster than the vehicle ahead.

You should accelerate very gradually when driving under slippery conditions. Using too much power in such conditions may cause you to lose control of your vehicle.

25. When driving in fog, you should:
Slow down.
Speed up.
Drive on the shoulder.

It is best not to avoid driving in fog. However, if you must drive under foggy conditions, be sure to decrease your speed.

26. When traveling down a downgrade, the speed of a vehicle will likely:
Not change.
Match the speed of traffic.

On a downgrade, the force of gravity will cause a vehicle's speed to increase. When approaching a downgrade, choose to travel at a speed that will be safe for the size and weight of your vehicle.

27. If a vehicle is equipped with an Anti-Lock Braking System (ABS), when the vehicle is started:
The brakes should lock up.
The ABS indicator light should turn on, then quickly shut off.
The steering wheel will not move until the air tanks are full.

After starting the engine of a vehicle equipped with an Anti-Lock Braking System (ABS), the indicator light should come on and then turn off. If the light stays on, something is wrong with the ABS.

28. Convex mirrors:
Cannot be used on vehicles transporting hazardous materials.
Can replace flat mirrors.
Can be helpful to see a wider area.
Are illegal to be used in most states.

Many large vehicles have curved, convex mirrors. Convex mirrors allow drivers to see a wider area than flat mirrors. However, they also make objects seem smaller and farther away than they really are.

29. Distracted driving:
Is not a concern.
Only happens when drivers are physically doing something, like using a cell phone.
Can occur due to mental activities, such as daydreaming.
Is encouraged on uncrowded roads.

Mental distractions can be just as dangerous as physical ones. It is possible for a person to look right at a hazard on the road but fail to notice it because their thoughts are occupied by something else.

30. When leaving your vehicle unattended:
The parking brake should be used.
The parking brake only needs to be used if the vehicle is parked on a slope.
The parking brake should not be used, as it can damage the tires.

In general, you should always use the parking brake when parking your vehicle. However, you should not apply the parking brake if your brakes are very hot or if your brakes are wet and temperatures are below freezing.

31. When trying to avoid a hazard:
Stopping is always effective.
Swerving may be more effective than stopping.
You may change lanes without looking.
You should drive on the shoulder.

Stopping is not always the most effective response to a hazard. You can usually turn out of the path of a hazard more quickly than you can come to a complete stop. However, swerving is not without its hazards, as it may result in a rollover in a vehicle that is either top-heavy or pulling multiple trailers.

32. When a brake pedal is pressed and the S-cam is turned, the S-cam:
Presses the brake shoes against the inside of the brake drum.
Tightens the brake drum onto the axle.
Presses the brake lining against the wheel.
Releases air from the air tanks.

When a brake pedal is pressed and the S-cam is turned, the S-cam presses the brake shoes against the inside of the brake drum. This causes friction and will cause the vehicle to slow.

33. If a five-foot-long item is placed on a flatbed trailer, it must be secured by at least:
One tie-down.
Two tie-downs.
Three tie-downs.

Cargo that is required to be tied down should be secured by at least one tie-down for every 10 feet of cargo length. However, at least two tie-downs should be used no matter how small the cargo is.

34. When driving, your mirrors should:
Not be used, as they are distracting.
Not be used unless there is traffic.
Be checked regularly.

It is important for you to be aware of your surroundings at all times. To do this, regularly check your mirrors.

35. Which of the following is acceptable if found during a pre-trip inspection?
Tires of mismatched sizes
Cracks in the tires
Tires manufactured by different makers

Be sure to thoroughly inspect your tires before a trip. Tire sizes should not be mismatched, and tires should not be cut, cracked, or otherwise damaged in any way.
