The HazMat endorsement is required by the states for drivers of commercial vehicles. The purpose of the HazMat endorsement is to ensure that drivers are aware of the hazards associated with the transportation of hazardous materials. When you need a job that requires the HazMat endorsement, preparing for the CDL knowledge exam is hard. The Connecticut CDL manual is overwhelming, filled with information that’s often confusing and hard to remember. You need something where you could supplement the dry information with exam-like practice. This HazMat practice test will help you prepare. We’ve designed it to be the tool that will help you pass the official exam with ease – by covering the same materials that the real exam is based upon. You’ll be getting instant feedback after each question so you’ll know why every answer is correct. The answers are explained with easy-to-follow language. You’ll study at your own pace, and even review specific questions if they give you problems. Good luck!

Practice questions were identical to the actual HazMat test in Connecticut.
All of the material made it easy to study. I spent a few hours across 2 days going over the material and felt completely confident in passing. I passed with 25 questions (1 incorrect, overthinking it). This was also way easier and price was better than attending the trucking school where I obtained my CDL.
A
Excellent course.
I used this course to get my hazmat. It was easy to use. I appreciated the audio and visual format of the course. There were so many practice questions which was super helpful to pass the test. I took my test and passed with 100% in less than 5 minutes!
JS
I have been driving truck for almost 34 years.
I have been driving truck for almost 34 years and held a hazmat endorsement for quite a few of those years. DMV could not find any records of my hazmat endorsement, so in order to get my hazmat, I was required to take the ELDT training. I reluctantly put the money out for the training, passed and got my certificate. All said and done, I'm glad I did, because not only did it help me to remember some of my previous training, but I learned there was a lot I didn't know. I would recommend it to every driver.
SAD
I was able to do my ELDT online.
I was able to do my ELDT online and it was submitted immediately! I went to DMV and was in the system. Couldn't believe how quick it was! Passed my Hazmat endorsement test 1st time out. The information contained in the coursework made it a breeze to pass!
