Which of the following is an example of statutory law?

Statutory law is defined as laws that are enacted by a legislative body, such as a state legislature or Congress. These laws are formally written and codified. The example of a law passed to regulate traffic safety is a clear instance of statutory law because it involves legislation that has been specifically created to address issues related to road usage, vehicle operation, and the safety of drivers and pedestrians.

This type of law is typically intended to be straightforward, providing explicit rules and regulations that govern behavior and ensure public safety. In contrast, constitutional amendments or common law decisions are based on different sources of legal authority. Constitutional amendments involve changes to the foundational legal document of a state or country and are not day-to-day, statutory regulations, while common law is developed through judicial decisions and precedents rather than through legislative enactments. Administrative rules, on the other hand, are created by government agencies and generally elaborate on existing statutory laws rather than being statutes themselves. Therefore, the law regulating traffic safety is the most fitting example of statutory law in the choices presented.
