ABSTRACT
As a result of the events of September 11, 2001, security services have expanded operations in all aspects of motor ¢eet safety and security.1 For many years, the trucking industry has worked to improve the security of trucking operations. In the aftermath of the terrorist activities, the transportation industry is expanding its security to include prevention of the use of its own vehicles and cargo (containers of explosive or combustible materials) as weapons in a terrorist attack. In June 2001, a gasoline tanker crashed, turning into a dangerous high-temperature inferno that destroyed a bridge on Interstate 80 in northern New Jersey. In another example, in a 1997 incident, an overpass was melted on the New York State Thruway.1
