Cheat sheet for cdl written test

I have taken the test . the practice tests that are online all over simply are almost useless . I have tried many of them and even the paid ones and even the paid ones off of our dept of revenue cdl site . No where near enough info to pass a test . this is why I post this . A good quick study guide that has actual questions from the test is needed . I know these questions are on the test . How ever it certainly is not all of the 140 questions . So add to it and make it better . It will help others .
Also here at least there are 3 different tests . If you fail you take a different one .

 

there is something odd about the computer test here . I can never pass it and I talk to others that say the same thing but we all pas the written test . Most likely bad software design I guess. I will see if I can copy the 100 questions I paid for off of the dept of revenue websites link . If I can I will post them . you would think if any practice tests were going to help you it would be the ones recommended by them on their site .
yet again I encourage people to add their known questions to the list as a study aid for others .

Anyway this is what the dmv sold me . Not bad but lacks many questions that are actually on test and has stuff about buses which should not even be on this test .
The questions about road signs actually do have the pic of sign on them they just did not copy off to here . there are also different signs in the test and I know we have around 70 I think it was listed in the manual for class C and the one I got on my last test I had never seen in my life and had no idea what it was.
