CDL Tests General Knowledge

They're pretty much the same questions. Best thing to do is read the book cover to cover and memorize it. The hazmat test is a little tricky as some things aren't in the book. There are 7ish different hazmat tests and its luck of the draw sometimes. If you get asked questions that aren't in the book you have a problem because you won't know them however that's one of those situations where they shouldn't be asking that question. Overall the test is pretty easy mine cut me off early each time didn't make me answer all of the questions on the computer. General knowledge is common sense, air brake is fairly straight forward remember 2 and 3 and 3 and 4 for air loss rates. And the trolley bar isn't a parking brake, tank is pretty easy, combination once again is mainly common sense, and hazmat is the pita. I don't have a hazmat enforcement but have taken the test twice passed both times, just never got fingerprinted and wasted the money on it. Good luck have fun and for gods sake make sure you clicked the right button before clicking submit.

 

Some questions will be on there with added ones.The web is full of practice tests with many different questions[ on the same test.QUOTE=sindrake;3368084]The Practice tests contained within this webpage are a very good guide, but how accurate are the questions when going to the DPS for a permit, I have it all down now but am wondering if the same questions will be asked In the DPS. will they?

Same Question for Air Brakes, combo vehicles, Hazmat, tanker[/QUOTE]

 

That's good just keep taking them and like I said read the book cover to cover. That helps emensly! When you mix taking the practice tests with the book and then Google around for more practice test it definitely gets you learning it. I will say this as well there are 50 questions on general knowledge air brake is 20 combo is 25 hazmat is 20 tank is 20 might be 15 but pretty sure its 20 questions. And there are different versions so questions might be different each time. I don't remember on the practice tests if they vary each time but if they do take all of them until you have seen each one at least once. I say this because you might get 90 on this one and fail the next one. Keep that in mind. Good luck and keep us up to date. After that its road test and were more than happy to give advise on that too!

 

Could be worse, you could live in New York. I have to get an endorsement for flatbedding (the one endorsement I didn't study for and missed). The only state that requires an endorsement for it...

Also, don't be afraid to just retake the tests right there if you fail. In NY, it's 5 bucks to retest. You know to take all the tests together, right? Well, in NY at least, any amount of tests or endorsements you take are one price all together, then retesting is the same and only costs 5 bucks. If you're at a nice DMV, if you fail a test, they might tell you what ones you missed. That's what happened with at least one guy in my class.

 

If you are not mechanically inclined, study hard on pre trip. It's basic stuff but might be a bit of a challenge for you if you aren't prepared. I don't know about the general knowledge test in Oklahoma but the one in Texas had a couple of odd questions. I don't remember them exactly but there was one that asked about which vehicle had to carry a fire extinguisher. I forget all the answers but one was gravel truck and one was a taxi. They didn't say what kind of gravel truck, could have been a 1/2 ton with a dump box or whatever. My mind was thinking Class A CDL not focusing on the question. I missed that one without a doubt.

The correct answer was taxi as they carry passengers. I wanted to kick my self for not taking the time and trying to understand the question better since it confused me.

As long as you are in test taking and study mode, take all of them if you can. Knowledge is power.
