Knowledge Test Questions

I've been preparing for my knowledge test (computer test before entering driving school) for a while, but today I found that the only available testing time within the next month is tomorrow so I'm "cramming" a bit. I have a few questions about some, err, questions I hadn't encountered before:

What is the most important reason for doing a vehicle inspection? A. Safety for yourself and others. B. Federal and State regulations require you to inspect your vehicle. C. A vehicle defect found during inspection can save you problems later. D. All of these answers are correct.

So the most important reason is all the reasons? Safety isn't more important than complying with regulations or avoiding "problems"? Is this really the correct answer to the question???

For an average commercial vehicle being driven at 55mph on dry pavement it will take about ___ to bring the vehicle to a stop. A. The length of a football field. B. Twice the length of the vehilce. C. Half the length of a football field.

The reason I ask about this is because a different testing source asked a similar question but indicated the braking distance as the correct answer rather than the total stopping distance. I just want to make sure that any questions not specifically mentioning the different distances (perception/reaction/braking) are actually looking for the total.

Which of these is important to check before driving in the winter? A. Steering. B. Exhaust. C. Tires.

I don't remember reading anything like this in the CDL manual. I only know the answer because I already encountered the question. Why is exhaust the most important in the winter specifically?

-----

Some of the "general knowledge" questions I've seen are related to buses, tankers, etc. The school I'm planning to attend didn't indicate I needed to cover those topics. Will the real test have questions about them?

Don't overthink the questions. Read them as you see them.

Asher,

You are taking a standardized test. It's not about what you think is right, it's about what they think is right. ;) get all the answers memorized, pass the test and move on.

Here's some more confusion:

How can you start moving without rolling backward? A. Engage the clutch before removing your foot from the brake. B. Apply the trailer brake hand valve. C. Set the parking brake whenever necessary. D. All of the above

Two things here. First, it's my understanding the the trailer brake hand valve (trolley valve/Johnson bar) should only be used to test the trailer service brakes. At least that's what the manual says. And in addition to that, on another site (cdl.com) with a similar question and answers, the correct answer was only to use the parking brake.

Two sites (cdl.com and cristcdl.com) I did tests on had a question such as:

Under-loaded front axles can cause the following: A. Poor traction B. Too much play in the steering wheel is not a problem. C. Damage to the tires. D. All of the above.

Here, I assumed the bit in italics was a typo. My initial thought was A. But one site (cdl.com, without the typo) said the answer was D and another (cristcdl.com, with the typo) said it was A. I don't know about damage to tires, but poor traction on steering tires wouldn't cause what I think of as 'play'. Unresponsive steering, sure. But to me steering 'play' is when you turn the steering wheel or shaft and the wheels don't turn, in other words something you check for during PTI.

Here's a fun one:

The basic two reasons to cover your cargo are 1. to protect the cargo from the weather and 2. A. Protect people from spilled cargo. B. Protect the roadway from spilled cargo. C. Protect vehicle following you from spilled cargo. D. All answers are correct.

Apparently the correct answer is D, even though the "explanation" says, and I quote, "The are two basic reasons for covering cargo: to protect people from spilled cargo, and to protect the cargo from weather." So is "protect people from spilled cargo" the right answer or not???

Here's my suggestion. Cramming obviously isn't helping you. Go take the tests. Skip over the questions you aren't so sure about. As you progress through the test those questions will come back up. Once you've gotten enough correct answers you pass.

Now... if you don't pass, take a better approach next time. It's not about memorization. It's all about knowing the material. When you know the material, those purposely constructed questions that throw you off won't be so hard to deal with.

So, how can you actually learn the material? First, you don't need 3 or 4 sources of sample test questions. That's only adding insult and intimidation. Second, use the most trusted resource in the nation for CDL test prep. The High Road CDL Training Program is the ultimate way to learn the material. Spend the time necessary with that program and you will be golden.

Thanks for the responses everyone. I passed the tests without a problem, missing only 3 questions.

Wish I had realized they were gonna take a new picture though, the stupid mask f'd up muh beard!
