About the Alabama CDL HazMat Exam
The Alabama CDL Hazardous Materials Endorsement Test is the written knowledge test for Alabama commercial drivers who need the H endorsement to transport hazardous materials requiring placards or covered select agents/toxins. The test is based on Alabama CDL Manual Section 9 and federal hazardous-materials rules, including 49 CFR Parts 171-180, with practical emphasis on shipping papers, placards, labels, markings, loading and segregation, emergency response, route and parking rules, driver responsibilities, and security awareness. Applicants also need the required TSA HME threat assessment, and first-time H endorsement applicants must complete FMCSA-approved ELDT HazMat theory before taking the knowledge test.
Assessment
Written multiple-choice CDL endorsement knowledge test covering hazardous-materials recognition, shipping papers, placards, labels, markings, loading and segregation, emergency response, parking and routing, security awareness, and Alabama/Federal endorsement requirements. ALEA does not publish a separate HazMat item count, so 30 reflects common CDL endorsement practice rather than a published Alabama-specific count.
