Free Nebraska CDL HazMat Endorsement Practice Test 2025

Welcome to the first step in adding the Nebraska Hazardous Materials (Hazmat) endorsement to your CDL! This description is your one-stop shop for familiarizing yourself with the process and, eventually, expanding your job opportunities and increasing your earning potential! In Nebraska, you’re likely already familiar with the state’s terrain, from the Great Plains to the challenging Sandhills region (grass-covered sand dunes in the north-central part of the state with loose soil and limited infrastructure). As you transport vital materials, including Nebraska’s famous corn, its natural gas, or veterinary vaccines, you will likely face flooding and narrow passes along the Missouri River Valley as well as challenging winter weather. But with these challenges come the rewards and the opportunity to increase your marketability and job recruitment in the industry by adding the Hazmat endorsement.

This endorsement is integral to drivers who are interested in transporting materials classified hazardous by the U.S. government. Without it, you can’t work on a huge number of cargo jobs. In the Cornhusker State, hazardous materials transported include anhydrous ammonia (used in agriculture as fertilizer), pesticides and herbicides, petroleum products, and industrial chemicals like chlorine and ethanol. Some prominent organizations in Nebraska, such as CF Industries (fertilizer and pesticide distribution with locations statewide), Sapp Bros. Petroleum Inc. in Omaha, and Novozymes in Blair (notable for producing industrial enzymes and chemicals) rely on Hazmat drivers. They often pay more for the additional expertise required to transport this type of cargo.

Let’s get you moving in the right direction! The process starts with a mandatory fingerprinting and background check conducted by the Transportation Security Administration (TSA). The results can take weeks, so do this first and use your wait time to study for the second step: the DMV knowledge test. This test covers federal regulations, substance handling, packaging, quantity limits, and transport configurations for hazardous materials. With a score of 80% on Nebraska’s 30-question knowledge test, you will pass the test (Nebraska CDL Handbook 2025).

Our Nebraska DMV Hazmat Endorsement practice tests have streamlined the process for you by avoiding unnecessary information and providing real-time feedback on each answer. Additionally, our practice tests resemble the official DMV test. Once you receive your TSA results and feel prepared, you’ll visit the DMV with the necessary documents, pay the fees, and pass the test.
