What does the 10th amendment allow states to regulate?

The Tenth Amendment to the United States Constitution serves to emphasize the principle of federalism by reserving powers not delegated to the federal government for the states. Among these powers, states have the authority to regulate a wide range of local matters, including criminal law. This amendment supports the idea that states hold the rights to legislate in areas that are not explicitly governed by federal law.

Focusing on the correct response, states have the power to create and enforce their own criminal laws, which can vary significantly from one state to another. This ability allows states to address local issues and concerns effectively, reflecting the needs and values of their populations.

In contrast, international relations, borders, and trade agreements are primarily the responsibility of the federal government. The U.S. Constitution assigns these powers to the federal government to ensure a unified approach in dealing with other nations and maintaining national integrity and commerce. Therefore, the focus of the Tenth Amendment highlights the balance of power between federal and state governments, particularly in areas like criminal law where states exercise significant control.
