What it means

The Transportation Security Administration states that the TWIC "is required by the Maritime Transportation Security Act for workers who need access to secure areas of the nation's maritime facilities and vessels."[1]

At the Port of New York and New Jersey the TWIC works alongside the Port Authority's SeaLink card: SeaLink is mandatory for truckers doing business at the port, and anyone with SeaLink identification must also have a registered TWIC.[2] Terminal operators list a valid TWIC, SeaLink card and RFID tag as requirements for every transaction.[3]

Example

A driver new to port work applies for a TWIC, then registers it with the Port Authority and gets a SeaLink card before taking a first load out of a Port Newark terminal.
