Cautelary jurisprudence is a type of law that helps protect people from getting hurt. It's like a big list of rules that people have to follow in order to make sure everyone is safe and not put at risk of getting hurt. For example, if you're driving down the street, there are rules that tell you to slow down around sharp turns or watch out for pedestrians. Cautelary jurisprudence makes sure those rules are followed and that people are behaving safely.
