Ready to jumpstart your Commercial Driver’s License (CDL) with instant access to more job opportunities and potentially higher pay? Adding the Hazardous Materials (Hazmat) endorsement to your Commercial Driver’s License (CDL) is a powerful way to do just that! The Hazmat certification enables you to transport materials that the U.S. government regulates as hazardous. Explosives, certain types of fuel, industrial chemicals, and radioactive materials represent a whole new set of opportunities on the horizon. Above all, this endorsement ensures the highest level of safety for you, the people around you, and the environment.
The process for a Hazmat endorsement requires you to be fingerprinted, pass a background check, and pass the DMV knowledge test. The topics covered in this test include federal regulations, material handling, packaging, transport configurations, and quantity limits. Delaware’s knowledge test is made up of 30questions and you’ll need a score of at least 80% (24 out of 30 answers) to pass (Delaware CDL Handbook 2025). This requirement ensures that you are well prepared for the responsibilities that come with transporting hazardous materials. Lastly, the minimum age for the Hazmat endorsement is 21 for interstate transport, and in Delaware, this applies to intrastate work as well.
Okay, having shared all of that, let’s get back to the potential income increase available with this endorsement. According to the 2025 Delaware CDL manual, the Hazmat endorsement allows drivers to handle more specialized cargo hauls! In Delaware, there are multiple industries with cargo transport requiring a Hazmat endorsement, including chemical manufacturing (DuPont and Chemours are notable companies here), petroleum and energy, agriculture, waste management, healthcare and pharmaceuticals, and manufacturing and industrial services. That’s a lot of new job opportunities, but it does sound a little daunting, right? It doesn’t have to be at all.
Our Delaware DMV Hazmat Endorsement practice tests strategically circumvent all of the unnecessary information you’ll come across during an internet search and organize only the most relevant material in a design that mimics both the structure and content of what you’ll face at the DMV site. When you feel ready, take your documents to the DMV, pay any fees, and take the official knowledge test.
