A more thorough explanation:

Definition: The term "interstate" is used to describe something that happens between two or more states or residents of different states.

Examples:

• Interstate highways connect different states in the United States.
• The company has offices in multiple states and conducts interstate business.
• When someone moves from one state to another, they may need to update their driver's license and car registration to comply with interstate laws.

The examples illustrate the definition of "interstate" by showing situations where something is happening between different states or residents of different states. The interstate highways connect different states, the company conducts business across state lines, and people need to follow different laws when they move from one state to another. All of these situations involve interactions between different states or residents of different states, which is what makes them "interstate."
