Which laws typically include regulations like speed limit laws and tax laws?

The correct answer is state law because it encompasses regulations that govern the specific needs and circumstances of a particular state. Speed limit laws and tax laws are primarily created and enforced at the state level, reflecting local policies, priorities, and the need for control over certain aspects of citizens' daily lives. Each state has the authority to establish its own set of laws and regulations, which can vary significantly from one state to another, especially in areas such as taxation and traffic control.

Federal law usually addresses broader issues that affect the entire country, such as immigration and national defense, while civil law typically deals with disputes between individuals or organizations rather than regulatory frameworks. International law governs the relationships between countries and does not pertain to domestic regulations like state-specific speed limits or tax codes. Thus, state law is the most accurate category for these types of regulations.
