Dedication pays off.
First of all, the company was very honest and helpful with informing me about the program and how it works. The material was so straight forward that the only thing that I had to do was sit down and commit myself and learn everything. I enjoyed how the material was presented to me. It wasn’t just thrown together like some other schools do just to make a buck, this was presented in a step by step tutorial that it made the material easy and fun to learn. But you have to put the time into it, I personally put 3 wholehearted days into it and my scores are proof of all my hard work.

It really took only a day?
I wasn't happy hearing that I needed to take the additional steps to get my HazMat certification and endorsement. driving-tests.org has an excellent service at a great price. I passed your website on to my brother. I signed up two nights ago and obtained three endorsements today. I think all three tests took approximately 10 minutes to pass. Really happy I found your website.

This is an amazing program.
I signed up two days be I intended to take my HazMat and Tanker endorsement tests. I completed the ELDT in a matter of hours then spent a few hours taking the practice exams the day before my scheduled test. I took both exams in less than 15 minutes and missed two questions due to a reading error on my part. This course is money well spent.

About the Tennessee CDL

The Hazmat endorsement permits drivers to transport materials that the U.S. government has judged hazardous. This responsibility is taken very seriously, and many additional requirements come into play. The endorsement process alone includes several hurdles to ensure your safety and protect the people and environment. Hazardous materials often transported in the Volunteer State include petroleum products, agricultural chemicals, industrial chemicals, explosives, and construction-related chemicals. There are many high-level organizations in Tennessee that require the endorsement for cargo transport. FedEx (Memphis headquarters), Eastman Chemical Company (Kingsport), Nissan North America (Smyrna), and Pilot Flying J (Knoxville) are a few examples.

First, you’ll need to pass a Transportation Security Administration (TSA) fingerprinting and background check. Results from TSA can take weeks to arrive. You’ll want to use that time to study and practice for the second hurdle: the DMV knowledge test. The knowledge test addresses federal regulations, substance handling, material packaging, quantity limits, and transport configurations for hazardous materials. You’ll need a score of 80% on Tennessee’s knowledge test, which is made up of 30 questions (Tennessee CDL Handbook 2025).

If all this sounds a little overwhelming, it doesn’t have to be. Keep your eye on the prize of more opportunities and potentially higher income. Our online Tennessee DMV Hazmat Endorsement practice tests are strategically designed to avoid any extraneous information you’d find by online search. We get straight to the point and have designed our practice tests to mimic what you will face on the official DMV test. We also provide immediate feedback on each response instead of waiting until the end of the assessment and bombarding you with corrections. Once you receive your TSA results and feel ready, you’ll visit the DMV with the necessary documents, pay the fees, and pass the test with flying colors.
