Practicing to take your HazMat endorsement? We have the ultimate challenge for you – introducing our free Oregon CDL HazMat Practice Test. Drawn from the same resource as the real test – the Oregon CDL Handbook – and also formatted like the real test, this practice test is as close to taking the actual HazMat exam as you can get. Our test features 30 questions covering such things as proper handling of hazardous cargo, penalties for improper handling, safe driving and more. A HazMat endorsement will allow you to begin transporting hazardous materials, such as explosives, gases, some solids, flammable and combustible liquids and other materials that may cause harm.

Sample questions like those that may appear on our practice test include: what are the major differences between cargo tanks and portable tanks? Do you need to stop before a railroad crossing if you are hauling 100 pounds of Division 4.3 materials? Questions on the HazMat test can be pretty technical and our practice test will help you gain experience answering these types of questions before you have to travel to the DMV and pay a test fee. You need to answer at least 24 of our practice test questions correctly to pass and you can take this test as many times as you like. We have also included answer explanations to help you learn. Ready to gain the knowledge and the confidence you need to earn your HazMat endorsement? Take our test now and check your HazMat knowledge level.
