MD CDL Hazardous Materials (HazMat) Practice Test 2025

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

Your livelihood depends on you passing your MD HazMat test. You hit the books, but you don’t feel as if you’re ready. You could just walk into the MVA and hope for the best, but that is a mistake. Instead of rolling the dice, take an Maryland Hazardous Materials practice test. It will get you prepared for the real test. Then, you’ll be sharp and ready to go on the big day.

Your Practice Test – What to Know

A CDL Hazardous Materials practice test closely resembles the actual test you’ll take at the MVA. The test’s 30 questions are taken from the 2025 Maryland CDL manual, just like the questions on the real exam. This way, you will come across the same types of questions on the practice test and the authorized test. They might be worded in a different way, but the meaning will still be the same. That makes the practice test the perfect way to get ready for taking your CDL Hazardous Materials test.

Since this is a practice test, use it as a way to get prepared for the big test. Take out your pen and paper and make a note of your weak areas. If something is giving you trouble, you can go back and study it. Then, take the practice test again and again until you ace it.

Then, you’ll be ready for test day.

Tackling the Test

Test day might feel stressful, but remember, you have prepared for it. You are ready to take on whatever comes your way. Just remember what you learned on the practice test, and you will be prepared.

Get those remaining jitters out of your system by taking the practice test again. After all, practice really does make perfect, and that will burn the answers into your head. Then, you will go in like a force to be reckoned with when you take your test.

Best of luck on your endorsement test. As long as you take your practice test and follow these tips, you shouldn’t have any problem whatsoever with your test.

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!
