What is defined as a rule made mandatory by a federal, state, or local government?

The term that refers to a rule made mandatory by a federal, state, or local government is "regulation." Regulations are legally enforceable rules established by governmental authorities to implement laws and ensure compliance with legal standards. They provide specific requirements that organizations and individuals must follow within a particular jurisdiction, often aimed at protecting public health, safety, and welfare.

Standards typically refer to established norms or criteria, but they are not always legally binding. They can be created by industry groups or organizations to ensure quality and safety in products and services, but following them is often voluntary unless they are incorporated into regulations.

Guidelines are recommendations that provide direction but do not carry legal weight; they serve as advice or best practices rather than mandatory rules.

Protocols can refer to formal systems of rules or procedures but are often used in specific contexts, such as medical or technical fields, rather than as general laws enforced by government entities.

Understanding the distinction between these terms is crucial for recognizing the legal framework and compliance requirements in various industries, including linework and rigging.
