MA CDL General Knowledge Marathon

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

Ready for something a little different? This Massachusetts CDL General Knowledge Marathon is a new practice test that contains all 693 questions from our database for this MA endorsement. If you select a wrong answer, we’ll remember that question and will display it to you again at the end of the exam 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”. Give it your best shot!

Real exam-style pitfalls you’ll practice:
Common Traps
Distractors
Trick Wording
Double Negatives

Best website for CDL and hazmat training.
You will pass! The practice hazmat tests are spot on! If you drive tractor trailer for a living, you need this valuable tool!

(Massachusetts) This is a must for any CDL driver.
Reading through the CDL manual is not enough. The questions and study material here are exactly what you need to know to pass the exams. Passed on the first try with combo and airbakes. My only regret is not taking all of the endorsements together!

I am not one of those people that can….
I am not one of those people that can open a book, read it and learn the material. I need hands on and repetition. This program is really fantastic in its design and I find myself not only learning, but having fun. My goal was to just learn the material and pass the tests, but I never thought I would enjoy the learning process. I find myself taking the quizzes over and over just to beat my last score, or get a perfect 100% I can now go take my CDL tests with confidence! I'm almost 60, I have not taken a "test" in a long time, my stress level went from 100% to almost nothing because I know I have really learned the material! I am even taking the tests for certifications I am not planning on getting because learning this way is so much fun!

CDL Prep.
Great resource! Studied the program and followed lessons as indicated for a total of 30 hours over 4 days. Passed CDL exam (general knowledge, air brakes, double & triples) in 35 minutes. Well worth it. I will be using it for all future test prep!

I knew nothing about tractor trailers and used this coarse for 5 days studying hard and long and now I feel like I know everything about trucking! thank you for making this curriculum! its worth 99 bucks if your a no nonsense do it right person. Id hard core recommend anyone who's looking to get into trucking to take this course!
