Which statement best summarizes the Coast Guard's enforcement authority under the law of the high seas?

• A. The Coast Guard can only enforce laws within U.S. harbors
• B. The Coast Guard enforces or assists in enforcing federal laws on, under, and over the high seas and waters subject to U.S. jurisdiction
• C. The Coast Guard has no enforcement authority beyond inland waters
• D. The Coast Guard enforces only maritime safety regulations

Answer: (B)

The main idea here is that the Coast Guard’s enforcement reach extends beyond inland waters and harbors to the high seas and to all waters under U.S. jurisdiction. They have the authority to enforce federal laws on the high seas—international waters where no single nation has sovereignty—as well as in waters subject to U.S. jurisdiction, such as territorial seas and ports. This authority includes taking action on the water’s surface, beneath it when needed, and in coordination with other agencies or nations in enforcement operations. That breadth is what makes the statement the best fit: the Coast Guard enforces or assists in enforcing federal laws on, under, and over the high seas and waters subject to U.S. jurisdiction. The other ideas are too narrow: enforcement isn’t limited to U.S. harbors, it isn’t confined to inland waters only, and it isn’t restricted to safety regulations alone.
