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 Illinois 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!

Worth your time.
I got it for my Hazmat test in Illinois. I did all the practice tests in two days. I took the actual test at the DMV the 2nd day. I passed the test. I missed 4 questions and I answered 28 out of 30 questions. I would recommend to take all of the practice tests and make sure you know all of the right answers.

So I am back.
Before I went to driving school this is the program I used. I took all 3 my exams missed 1 question one one. Missed 2 on the another and got a perfect 100% on the last test. So I am back to get my hazmat, double triple, and tanker license. Just to let you all know I am 51 and 7 kids, last child turned 18 in March and proud to be starting driving with my husband. I really doubted myself when I started this program. Put in the work and you shall succeed.

ELDT hazmat.
The material was easy to use. It covered a lot of material not in the handbook and went into more detail than the handbook. I have a better understanding of the material and a lot of good practice tests.
