The Department of Homeland Security (DHS) on Tuesday, August 17, said that trucks carrying freight into the United States from Canada and Mexico would need to file electronic manifests with the government at least 30 minutes before arriving, the Associated Press reported. Depending on where they enter the country, trucking firms have three deadlines: November 15, December 15 and January 14, 2005. DHS said the information from trucking companies would be compared with law enforcement and commercial databases to target potentially dangerous shipments. These new security rules were supposed to take effect in March, but they were delayed because the government’s computer software had to be adapted, The Associated Press said.
