MD CDL Hazardous Materials (HazMat) Marathon

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

Need one final boost? This Maryland CDL Hazardous Materials (HazMat) Marathon is a lengthy practice test that contains a mix of all 193 questions that we have available for this MD endorsement. If you make a mistake, 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”. It might take some time, but you can do this!

First step to trucking school.
I always use this platform I was able to get my CDL A permit in less then 15 minutes, each test took me less then 4 minutes. I was able to get my hazmat and tanker in less than 10 minutes. I now have my CDL class A with hazmat and tanker and it all started here.

Hazmat Endorsement.
At the end of March, I went to take the test to get my hazmat endorsement, only to discover that I needed to take some type of class before taking the test. I found driving-tests.org and determined that it was approved. I completed the requirements, all online, went back to take the test and got all of the first 24 questions (out of 30) correct, and the test ended because I already had a passing grade. I was confident when I went to take the test the 1st time, but I know that doing the program through driving-tests.org enable me to pass with no problems.

Extremely tremendous!
They have multiple practice test and also valid valuable information that is extremely important to prepare for your CDL! I needed the ELDT for hazmat due to the new law and this is where i got it! They send everything right over after completing the requirements! Don’t worry, the requirements are as easy as tying your shoes! The best part is there’s a test that allows you to cover what you did not get correct! It literally drills this into your head! I went to the DMV 3 days later and i successfully passed my Hazmat TEST! I would definitely recommend this service and have to several new CDL holders that fall under the new law!
