A more thorough explanation:

Imperative law is a set of rules that people must follow because they are commanded to do so by an authority that enforces obedience. It is a type of law that is imposed on individuals through social pressure or the force of a politically organized society.

For example, traffic laws are imperative laws that people must follow when driving on the road. Failure to obey these laws can result in fines or even imprisonment. Another example is tax laws, which require individuals to pay taxes to the government.

Imperative law is different from other types of law, such as natural law or moral law, which are based on ethical or moral principles rather than commands from an authority. Imperative law is enforced through the legal system, which includes legislation, judicial precedents, and accepted legal principles.
