Did you know that in Connecticut, commercial drivers must perform a pre-trip inspection of their vehicle at the beginning of their shift? Federal and state laws mandate pre-trip inspections to ensure commercial vehicles are safe and in proper working condition before they go on the road. As you begin your learning phase, it is crucial to develop good habits that will serve you throughout your career. You can find more information on pre-trip inspections and other aspects of commercial driving theory in the official Connecticut Commercial Driver’s License Manual (Connecticut CDL Handbook 2025). Read this manual multiple times, and when you’re ready, you can use our practice tests to evaluate your knowledge.

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!

About the Connecticut CDL

Our Connecticut CDL Class B Practice Test closely reflects the content and format of the official general knowledge test, helping you get an idea of what to expect on exam day. It consists of 50 multiple-choice questions that will evaluate your knowledge of safe driving practices, air brake systems, and emergency situations. You get unlimited attempts and nonstop access to train as often as your schedule allows. Run a quick session while the dinner cooks, during football halftime, or at the end of a busy day.

Customize your testing experience with the test settings menu, which can be opened by clicking the three dots in the top-right corner of the page. From there, you can toggle features like voice-over and ambient music. For added flexibility, you can also take this practice test using only your keyboard. Use the “Shift + ?” key combination to display a list of available shortcuts.

A detailed explanation of the correct answer is provided for each question. You can use this feedback to strengthen your knowledge and learn from your mistakes. For future reference, we recommend noting it in a notebook or notebook app. This way, you can understand the reasoning behind each correct answer instead of memorizing them mechanically.
