CT CDL General Knowledge Marathon

Perfect for first-time and renewal CDL/CLP applicants, and those adding endorsements.

Got a couple of hours to spare? This Connecticut CDL General Knowledge Marathon is a massive practice test that contains all 693 questions from our database for this CT endorsement. If you make a mistake, we’ll remember that question and will display it to you again at the very end of the Marathon until you’ve answered that question correctly. In other words, the Marathon will cycle through your missed questions until you answer each one correctly. You must make a 100% to pass. We suggest you attempt this one after you have practiced the state’s “regular” tests, but before the “Exam”. It might take some time, but you can do this!

Real exam-style pitfalls you’ll practice:

Trick Wording

Was in and out of there within minutes.
I was in and out of there within minutes. So I recommend this. It's insurance to make sure that you get an actual career going, because without this, without the actual permit, you're going nowhere.

Best site.
It is very easy to navigate through the different tests. All the information is very helpfull, especially the Ai assist incase you ever have a question. Update 04/15/24: Passed my cdl permit exams first try. Questions were practially spot on with the practice tests

The learning questions are 100% realistic.
The questions are almost the real questions as in the exam. More importantly, there are no superfluous questions. To test my skills further, I used another app on the market for a short moment, which asked questions that were not on my CDL exam at all. For example, no traffic signs are asked. Therefore, I can say that you can rely on the questions and your own learning progress with Driving-Test. I finished my written exam after a few minutes. And it's worth mentioning, I just recently moved to the US and am not a native English speaker.

Great site.
I was using another for 3 weeks and I failed on my first attempt. I went to driving-tests.org 2 days before the test. I crammed and passed my cdl permit just in time to start my class.

While searching for information about….
While searching for information about how to obtain a Commercial Driver's License I came across the website. The information I found there was clear and concise. As I spent more time on the site, I found more information specific to my needs. I was really happy when I got to the portion of the site which offers test preparation materials. The methods used by Drive-Tests fit my learning style and I have gained confidence as I approach my test at the Department of Motor Vehicles.

This Program IS THE Real CDL DEAL!
This program is the real deal. I took 4 tests today - the CDL General Knowledge, Air Brakes, Combinations, as well as the Class C. There were no surprises! After going through the program I can honestly say that I aced each test. I can't remember ever being so well prepared for a test of any kind before! If you want to pass your CDL with flying colors - then this is the program for you. I can't say enough good things about it!
