Free Utah CDL HazMat Practice Test 2024

In the Beehive State, commercial vehicle drivers are essential to keep the economy moving. Receiving your Hazardous Materials (HazMat) endorsement ensures that you have studied and are certified to carry more varied types of loads safely, and taking practice tests is one useful way to prepare for your endorsement exam. Today, you can take a free practice test with 30 multiple-choice questions designed to simulate the real exam and based on information from the Hazardous Materials section of the Utah Commercial Driver’s License Manual. Each question has a hint and an explanation. It is recommended that you read each explanation carefully, as they contain even more facts and figures about each subject, which will help you answer future questions correctly the first time. Return and retake this practice test as often as necessary until you feel confident in your score (80% or higher recommended), and this should help you pass your HazMat endorsement exam. Good luck both now and on your real exam, and drive safely!

  • Perfect for first-time and renewal CDL/CLP applicants, and those adding endorsements
