100+ Free TWIC Practice Questions

A TWIC (Transportation Worker Identification Credential) is a tamper-resistant biometric smart card issued by TSA. It is required by the Maritime Transportation Security Act for all persons needing unescorted access to secure areas of MTSA-regulated maritime facilities, vessels, and OCS facilities. This includes merchant mariners, port truck drivers, longshoremen, terminal employees, contractors, and rail workers — approximately 1.5 million+ workers.

Apply by pre-enrolling online at the TSA enrollment portal, then visiting an IDEMIA/IdentoGO enrollment center to provide identity documents, fingerprints, and a facial photo. The standard fee is $124.00 (reduced to $93.00 if you hold a valid HME or FAST card). TSA conducts a Security Threat Assessment including criminal history, immigration, and terrorism watch list checks. Processing takes 30-60+ days, so apply at least 60 days before you need the card.

Visual TWIC inspection involves matching the photo to the individual, verifying expiration, and checking security features for tampering. Electronic TWIC inspection uses a certified reader to authenticate the card digitally, verify it has not been revoked via the Canceled Card List, and perform a biometric fingerprint match. Risk Group A (high-risk) facilities must use electronic inspection; other facilities may use either method.

MARSEC (Maritime Security) has three levels: Level 1 (normal operations with baseline security), Level 2 (heightened threat with additional security measures), and Level 3 (exceptional threat with maximum security). Each level requires progressively stricter security measures as defined in the facility's approved Facility Security Plan. TWIC readers can be configured with different authentication modes for each MARSEC level.
