A more thorough explanation:

Definition: State law refers to the body of laws that govern a particular state. It includes the state's constitution, statutes, regulations, and common law. This is different from federal law, which applies to the entire country.

Examples:

• In California, state law requires drivers to stop at a red light and wait for it to turn green before proceeding.
• In Texas, state law allows individuals to carry a concealed handgun with a permit.
• In New York, state law prohibits smoking in public places like restaurants and bars.

These examples illustrate how state law can vary from state to state. Each state has its own set of laws that are enforced within its borders. These laws can cover a wide range of topics, from traffic regulations to gun control to public health.
