Laws differ between U.S. states because of federalism, allowing states to create their own laws for local issues (like family, property, and most criminal law) that supplement or sometimes diverge from broad federal laws (covering things like immigration, civil rights). These variations stem from states addressing unique needs, history, geography, and demographics, leading to differences in everything from marijuana legality and gun control to licensing requirements and specific traffic rules, with federal law always taking precedence if there's a direct conflict.
