If you’re in Pennsylvania, this CDL HazMat practice test is for you!
All drivers with a valid Pennsylvania Commercial Driver’s License (CDL) or in the process of obtaining one can apply for a Hazardous Materials (H) endorsement. This endorsement allows them to transport high-risk cargo such as explosives, flammable gases, pesticides, and even infectious substances and radioactive materials. Because these products can severely harm human beings and the environment, they must be handled exclusively by trained professionals.
To obtain a HazMat endorsement, you must pass a specialized knowledge test. It covers topics like hazard classification, safety and emergency protocols, proper transportation of hazardous materials, and labeling requirements. All these details can be found in the official 2026 CDL manual (https://driving-tests.org/pennsylvania/pa-cdl-handbook/), which contains everything you need to know to pass the written exam. You must also pass a Transportation Security Administration (TSA) Threat Assessment (background check).
Students dedicated to mastering this endorsement often use various online resources, significantly improving their learning process. Our practice tests closely resemble the official knowledge exam, allowing you to practice in as many sessions as needed. There is no time limit for answering the 30 questions, all of which are related to the HazMat endorsement.

This way, you don’t have to wait until the end to see your score since it is updated as you go.
Because this is a practice test, there’s no need to rush. It’s perfectly normal to fail on your first few attempts, so don’t get discouraged by a low score. Instead, focus on learning from your mistakes and develop a better understanding of the correct answers.
