Free New Jersey CDL HazMat Endorsement Practice Test 2025

Whether driving through the Appalachian Mountains (especially the challenging Kittatinny Ridge), the forested Pine Barrens in the south, the coastal plains, or the urban congestion of Newark and Jersey City, New Jersey is a diverse state with much to offer. If adding the Hazardous Materials (Hazmat) endorsement to your Commercial Driver’s License (CDL) is your objective, you’ve come to the right place. The Hazmat endorsement increases your marketability and recruitment potential and can result in higher pay! Enough said? Let’s take a closer look.

The U.S. government has judged certain materials as hazardous, and the Hazmat endorsement permits drivers to legally transport these materials. Hazardous materials transported in the Garden State include petroleum products (gasoline and diesel fuel), industrial chemicals (chlorine and sulfuric acid), propane and other compressed gasses, medical waste and other biohazards, and agricultural chemicals (fertilizers and pesticides). There are many high-level organizations in New Jersey that require the endorsement, including ExxonMobil (located in Bayonne), Merck & Co. (headquartered in Kenilworth), Linde Gas North America (Bridgewater), BASF Corporation (Florham Park), and PSEG (Public Service Enterprise Group) (Newark).

Because of the increased responsibility and need to maintain public safety (and yours!), many additional requirements are necessary to add the endorsement. First, you’ll need to pass a Transportation Security Administration (TSA) fingerprinting and background check. Results from TSA can take weeks to arrive. Strategically use that time to study and practice for the second hurdle: the MVC knowledge test. The multiple-choice 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 New Jersey’s knowledge test, which is made up of 30 questions (New Jersey CDL Handbook 2025).

If all this sounds overwhelming, check out what we’ve done to streamline the process for you. Our online practice tests are designed to avoid the fluff of extra information you’d find searching online. We designed our New Jersey MVC Hazmat Endorsement practice tests to mimic what you will face on the official MVC test. We’ve also researched information retention and designed the tests to respond immediately. If you miss a question, our automated assistant will provide reasons for another choice as the answer. Once you feel prepared and have your TSA results in hand, you’ll visit the MVC with the necessary documents, pay the fees, and pass the test.
