News release: “The Transportation Security Administration (TSA) today announced a set of security recommendations for the transportation of certain quantities of hazardous materials across the nation’s highways. The recommendations – while voluntary – will help to ensure the secure transportation of potentially dangerous materials that could cause a significant impact if used in an act of terrorism. The voluntary guidelines were developed over a three-year period by TSA’s Highway and Motor Carrier Division, in close collaboration with government and private sector partners. The resulting recommendations are structured to allow motor carriers and shippers to adopt measures best suited to their particular circumstances or operation.”
