TSA conducts the Hazmat Threat Assessment Program (HTAP), which drivers must successfully complete to obtain or maintain the H endorsement for hauling hazardous materials on their Commercial Driver’s License (CDL). The TSA clearance is valid for five (5) years and must be renewed along with the CDL unless the existing clearance covers the new CDL period.
