"Technology could reduce the risk by a third, but at a cost of $1.1 billion to the industry. Since 9/11, the federal government has tightened trucking security. The Department of Homeland Security (DHS) began in 2004 requiring fingerprinting and background checks on drivers with hazmat licenses. It also instituted a "highway watch" program to help drivers spot threats. The Department of Transportation also requires hazmat truck companies to have detailed security plans. "There is a much sharper realization among hazmat truckers since 9/11 that you've got to be more alert," says John Conley, president of the National Tank Truck Carriers Association. That includes "things as basic as locking your truck. Our drivers understand their loads could be used in a bad way.""
