Indiana CDL HazMat Practice Test 4 2025

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

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 Indiana 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!

Easy to follow and to learn.
It also helps I’m a fast learner, I took the test one day after studying the hazmat material and passed with ease. For those who can learn by making educated guesses and being told what the correct answer is after, this is a great source to attain endorsements.

I give driving-tests.org a 5 star.
They were more than helpful in getting me to pass my eldt class. In fact I passed their class and took the hazmat test at the dmv the next day and didn’t miss a single question! Also I went camping and wasn’t able to do my class the first time so they reinstated my week long course free of charge.
