Agencies that possess statewide police powers for both traffic regulation and criminal investigations are known as State Police. These agencies are specifically designed to enforce the law across an entire state, offering a broader jurisdiction than local police departments. This allows State Police to engage in various law enforcement activities, including patrolling highways, investigating serious crimes, and assisting local law enforcement agencies when needed.

State Police often serve crucial roles in traffic enforcement, accident investigation, and addressing criminal activities that cross jurisdictional lines. Their ability to operate statewide makes them an essential component of the criminal justice system, especially in areas where local agencies may lack the resources or authority to handle certain situations effectively.

In contrast, local police typically have jurisdiction confined to specific municipalities or towns. Highway Patrol agencies focus primarily on traffic law enforcement and highway safety but may not engage in broader criminal investigations. Special District Police generally serve specific areas or functions (like schools or transit systems) and do not possess comprehensive statewide powers.
