With the driving program and tests, I was able to pass my DMV exam.
I only got like one or two wrong. Every question that was on the test was actually on the DMV test too.

I was wanting to obtain my cdl license….
I was wanting to obtain my cdl license and i decided to read the info that the dps office tells you to download and study. It was so confusing and so much information that i was overwhelmed. My buddy told me he tried it but failed. Then he told me about Driving-Test.org. He said listen "it cost a few bucks but i promise you you'll pass". I said ok! I bought it for maybe a 100 bucks, read it and studied for 2 days straight. I went and took 2 test and aced them. I was like holy s@$!t this is the truth. Then i went the next day and aced the other 2. I didnt second guess at all. Everything thats on Driving-Test.Org is on the test. I would have never guessed it was as good as it is bc i actually ran across it before but didnt purchase it. The free one is ok but you wanna get the one you have to pay for and its like a 100 bucks n change maybe 120 but its worth it. You dont have to believe me bc i have my permit already😜 Best investment of my life.

To everyone who has failed the cdl….
To everyone who has failed the cdl general knowledge test. I too failed the test twice! Even after using the free tests this site offers. Although it was helpful I still failed. After purchasing, I studied for a few hours, went in the next day and passed with confidence! I would highly recommend paying for the use of this site. It will save you time, intern save you money! Please learn from my mistakes. Hope this helps.

Passed with flying numbers!
I went and tried to take my first 2 test for the class A CDL, witch was special requirements and General knowledge I only read the handbook, I ended up failing the General knowledge. I downloaded the program studied for probably 5-6 days and aced the rest of my tests in one sitting only missing 5 out of 95! Highly recommended!

Best online practice tests.
I found this website while searching through tons of sites to help practice for the CDL permit. I tried my permit test 3 times and failed, I knew i had to try something different. When i came across this site I studied one full day and felt confident enough to go take the exam the following day and I passed!

Best money spent ever!
Took a class and read the manual to prepare for the written CDL-A test and didn't feel ready. Driving Tests prepared me so well that I besides the General Knowledge, Combination, and Air Brakes tests I also took the Haz-Mat, Double-Triples, and Tanker tests all on the same day. The test moderators were surprised on how quickly I finshed all 6 tests. I highly recommend Driving Tests to help you get your CDL.
