Available in EN and ES

Now is the time to start preparing to take your Hazardous Materials (HazMat) endorsement exam, and a great way to do this is with a free practice test. This 30-question multiple-choice test is based closely on information from the Washington Department of Licensing Commercial Driver Guide. Each question also includes a hint and explanation. You’ll want to read each hint and explanation closely, as these are designed to help you answer future questions correctly that may be worded differently on your real HazMat exam. We recommend taking the practice test as often as necessary until you achieve a passing score that will help you feel confident on exam day (80% or higher recommended), which may help you pass your HazMat exam the first time. Good luck both now and on the HazMat exam, and drive safely!

Enhance your HazMat endorsement preparation with our straightforward HazMat practice test collection, and consult our HazMat endorsement guide for essential tips and information.
