Positive law is a type of law that is made by people, like the laws that you have in your city. These laws tell people what they can and cannot do, and they are enforced by the police and the courts. For example, your city might have a law that says you have to wear a seatbelt when you're in a car, and if you don't follow this law you might get a ticket. Positive law is important because it helps us all stay safe and so that we can live peacefully together.
