Vessel Traffic Service (VTS) is operated in designated waters by which agency?

• A. U.S. Coast Guard
• B. Federal Communications Commission
• C. National Oceanic and Atmospheric Administration
• D. International Maritime Organization

Answer: (A)

Vessel Traffic Service is a shore-based system that monitors and directs vessel movements in busy waterways to prevent collisions and improve safety and efficiency. In the United States, that service is operated by the U.S. Coast Guard in designated waters. The Coast Guard is responsible for maritime safety and security, including traffic management, so it runs the VTS centers and coordinates with ships there. The other organizations handle different roles: the Federal Communications Commission oversees communications, NOAA deals with weather and nautical charts, and the International Maritime Organization sets international standards but does not operate VTS in U.S. waters.
