TN CDL General Knowledge Practice Test 2 2025

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

This second TN General Knowledge practice test contains another set of 50 questions based on the official CDL manual. Just like the first practice test, this one is also designed to prepare you for the General Knowledge portion of your 2025 Commercial Driver’s License exam. There are several answer options, but only one of them is correct. Each question also includes a hint and an explanation. It is recommended that you check each question’s explanation to gain some further insight into the rule being tested. Every time you answer a question, you’ll get immediate feedback with a detailed explanation, so you won’t need to wait until the end of the test to know the correct answers. Good luck and drive safely!

When I went to do the test, I passed in the first first try.
Started like three weeks before the exam, and let me say, going over and over those questions, studying the manual, it was like a review. So I would recommend this platform to anyone who is planning to do the test. It's such a great resource.

Process was very easy to get started.
It was step by step all the way through. I passed hazmat and tanker first try within just 2 days of using the software.

Dedication Pays Off.
First of all, the company was very honest and helpful with informing me about the program and how it works. The material was so straight forward that the only thing that I had to do was sit down and commit myself and learn everything. I enjoyed how the material was presented to me. It wasn’t just thrown together like some other schools do just to make a buck, this was presented in a step by step tutorial that it made the material easy and fun to learn. But you have to put the time into it, I personally put 3 wholehearted days into it and my scores are proof of all my hard work. Monday 9th I will take my 3 endorsement test at my local DMV, my confident that I will pass is not an issue because of my dedication to this program. The 3 test are as followed: 1) H-Hazmat 2) T-Tankers 3) D-Doubles & Triples Thank You so much. Sincerely, Heidi Grace Sundermier Toone Tennessee

I’m just a regular guy.
I was skeptical about all those driving manual study guides, or the other web based tests. Driving-tests helped me pass my class A CDL permit test and get an endorsement. It is clean and simple to use. Honestly I will use them again when I choose to get another endorsement.

Good experience.
Good experience, general tests involve mixing A and B together but I’d guess that’s true everywhere. (Am learning for exclusively B.) In depth involved useful, I’d recommend. My best wishes to the company hope they continue in business. Also got the school bus and passenger endorsement ELDT. Over 600 questions 11 hours of video for the general CDL training alone. If you don’t know where to start this might be a good place.
