MD CDL General Knowledge Marathon

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

Need one final boost? This Maryland CDL General Knowledge Marathon is a lengthy study tool that contains all 693 questions from our database for this MD endorsement.

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”. Delivers some serious studying power! Do your best to complete this mega test!

Took this. I went down to the motor vehicle, didn't miss one.
I took this. I went down to the motor vehicle, didn't miss one on any of my tests, nothing! I walked right through it. It was very simple. Like I said, you know, it gives you a multiple choice. You make your answer—if you get it wrong, on the bottom, it gives you a brief paragraph of what the correct answer is. And it was just so helpful. I mean, that's what I like most about it—it was so easy, and I've recommended it to quite a few of my friends.

Program is definitely.
This program is definitely I hope more people use this program and have the success in passing the CDL B and others that it offers. I am extremely grateful

The best study guide for MVA CDL knowledge tests.
I finished my Tanker endorsement test in less than 7 mins! I finished my Double/Triple in 8 mins and few seconds! I took both tests the same sitting back-2-back. Your learning tools are AWESOME!

Really trust this website.
After hours of searching online for a trusted website where I can complete my hazmat ELDT, I am so glad I found Driving-tests! The website it self looked legitimately, it had many reviews/endorsements that made it seem like a safe website to use, that to me was a big deal, all the other websites that I looked at just seemed very sketchy, and it didn’t feel safe enough for me to put down any personal information. The price seemed very reasonable compared to others as well.
