Laws change to keep up with the ever-evolving views and values of the society. Lawmakers play a critical role in identifying shifts in expectations and values of the society so as to create and pass new laws.
The law is flexible to ensure that changes made in the future take into account new views and values. Things that change within the society that require changes in the law include ethics, technology, morality, social values and events. In order for the law to work, it must accommodate such changes. For example, the invention of vehicles led to the development of roads, which led to the creation of new laws and regulations.
