he Department of °®¶¹´«Ã½land Security said last week it has started conducting background checks on hundreds of thousands of port workers, the first step in unveiling the Transportation Worker Identification Credential, commonly referred to as TWIC.

Following the announcement, an official with American Trucking Associations said the group supported the plan, but was concerned about its costs.

First proposed in 2002, the TWIC program would provide a single credential for transportation workers with unescorted access to U.S. ports.
