Are you ready to become more competitive among other commercial drivers, potentially earning more income in the process? Adding the Hazardous Materials (Hazmat) endorsement to your Commercial Driver’s License (CDL) is one of the most effective ways to boost your earning potential and expand marketability in Wyoming. With this endorsement, you qualify to haul loads that the U.S. government has deemed hazardous and set yourself apart from non-endorsed drivers, who have no access to this sector.

In the Equality State, common hazardous materials include oil, natural gas, ammonium nitrate, propane, and agricultural chemicals. Major companies such as Halliburton in Casper, Sinclair Oil Corporation, and Black Hills Corporation in Cheyenne depend on drivers who hold this endorsement. This small list represents just a few in a much larger list of opportunities and pay raises awaiting you once endorsed.

To receive the endorsement, the U.S. government requires three major steps. First, you must ensure that all Entry-Level Driver Training (ELDT) requirements have been met. Next, you’ll need to pass a fingerprinting and background check conducted by the Transportation Security Administration (TSA). While you wait for what is often several weeks for these results, you will want to study for the third and final step: passing the DOT HazMat Knowledge Test. This test covers federal regulations, handling and packaging requirements, quantity limits, and transportation configurations for hazardous cargo. Wyoming’s test includes 30 questions, and you’ll need to score at least 80% to pass (Wyoming CDL Handbook 2025). Failing the test can result in delays and added fees, which we can certainly help you avoid.

Best test out.
I was already using this to study to take the Hazmat endorsement. I went to the dmv and was told I need to take the ELDT. Luckily for me I was already using this test so I passed on the first try. Same questions that are on the test.

Passed all 4 exams, Hazmat, combo, air brake doubles and triples.
I was using other sites for my studies, but thought I was missing something. I had 6 days till my CDL-A DMV tests, I took the Hazmat, Combo, Air Brake and Doubles/Triples exams and passed them all in one sitting. The feedback and explanations of wrong answers really helped me grasp the full answer of the questions and this helped me throughout my studies. Def worth the price for as long as you need it. John.

Guaranteed To Pass!
I took ELDT with Driving-Tests back in January and got my certificate. I wanted to get my HazMat, Tank and Double/Triple Endorsements and knew of only one place that made it easy for me to pass my Official Exam and I am officially a CDL-A: w/ X, T Endorsements!
DB
I only had one day to crunch….
I only had one day to crunch to study for my license renewal with my hazmat and taking endorsement I study everything I could took the random testing over and over when I went to the DMV I felt I already was familiar with the testing procedure and how to strategize myself to skip questions that I didn't know and only answer the questions I knew I passed with flying colors 100%. This course is well presented well organized if you never had a license of the CDL this course will guarantee you you will pass and give you the confidence to pass if you're nervous at test taking that's one time investment for for this one month I will do it again and suggest anyone who needs this course to take it.

I had to renew my HazMat.
Even if you have your HazMat and are just renewing it this is good to have, things change. I failed the first time, only by a couple, went home, got online, got this and went back a couple days later and passed. I'll keep it in my computer for a refresher.
