What Is a 100 Police Code? 100 Police Code

The 100 police code meaning for the police forces is Hit And Run.

If you’ve ever listened to a police scanner or followed law enforcement activity reports, you might have come across a series of numerical codes used in their communication. One such code that often raises questions is: what is 100 Police Code? The 100 Police Code is commonly used to refer to a Hit and Run incident—an offense where a driver is involved in a traffic collision and leaves the scene without identifying themselves or offering aid to anyone who might need assistance.

The purpose of police codes like 100 is to streamline communication and reduce confusion during emergency responses. Rather than using long, descriptive sentences over the radio, officers can quickly state “Code 100” to indicate a Hit and Run situation, which helps speed up dispatch coordination and field response. It’s part of a broader set of codes used by law enforcement agencies throughout the United States to maintain clarity, especially during high-stress moments where every second matters.

History and Use of the 100 Police Code in Law Enforcement

To understand 100 Police Code, it helps to know the history of police codes in general. Police codes originated in the late 1930s, officially developed between 1937 and 1940 as part of the APCO Ten Signals created by the Association of Public-Safety Communications Officials-International. These codes were later expanded in 1974 to accommodate the growing complexity of police work and the rising need for standardization across jurisdictions.

The 100 Police Code gained its usage as vehicular incidents, especially Hit and Run violations, became more common on busy city streets and highways. Officers rely on this code to quickly notify dispatch and other units that they are responding to a scene involving a driver who fled the scene after causing a collision—sometimes involving injuries or fatalities. Due to the serious nature of these events, responding quickly and efficiently is critical, and having a universal code like 100 helps achieve that.

So, what is 100 Police Code? Simply put, it refers to Hit and Run—a crime that can carry severe consequences for the driver involved. In many states, fleeing the scene of an accident, especially when there are injuries or property damage, is classified as a felony. The 100 Police Code helps officers communicate this specific scenario clearly without needing to provide a detailed explanation over a crowded radio channel.

By stating “100,” officers are indicating that a driver failed to stop after an accident, which triggers a standard response procedure. Law enforcement might begin searching for the vehicle, alert nearby patrols, or initiate traffic stops in the area based on witness reports or surveillance footage. It’s a crucial part of real-time communication in law enforcement’s fight to keep roads safe and ensure accountability.

History of Police Codes: From Morse to Modern Radio Signals

Police codes have an interesting origin story. They were first introduced between 1937 and 1940 as part of the APCO Ten Signal system, a framework designed by the Association of Public-Safety Communications Officials-International (APCO). The goal was to create a standardized method for dispatchers and officers to communicate quickly and reduce confusion on public safety radio channels.

The idea was inspired in part by earlier Morse code practices used by the U.S. Navy. In fact, APCO’s proposal for brevity codes first appeared in their June 1935 bulletin, evolving over time into the voice-based ten-code system still used today. For example, when an officer finishes their shift and reports out of service, they may use a 10-7 code, followed by a 10-42 to indicate the end of duty.
