In order to obtain the Hazmat endorsement drivers are required to pass a Transportation Security Administration background check and a knowledge test. The Arkansas hazmat test consists of 30 questions. To pass, you must correctly answer at least 24 questions (80%). The AR CDL hazmat test covers the information found in the Arkansas CDL Manual.
