Code 55 Police
Code 55 Police details, meaning for the police force is Intoxicated Driver (10 55 police code).
Code 55 Police, also known as 10-55 Police Code, is a widely recognized communication code used by law enforcement officers, highway patrol units, and sheriff’s departments across the United States. This specific code is used to indicate the presence or report of an intoxicated driver. When an officer observes a motorist displaying signs of impairment—such as erratic driving, swerving, or ignoring traffic signals—they may radio in a “Code 55” or “10-55” to alert dispatch and request backup or initiate a DUI stop.
Law enforcement agencies rely on coded communication systems like this to quickly relay important details without creating public panic or confusion. By using Code 55, officers are able to act swiftly and coordinate efforts to handle potentially dangerous situations involving impaired drivers. This code is part of a broader police radio code system that includes everything from emergency alerts to routine traffic incidents.
Understanding what Code 55 means can be helpful for those studying criminal justice, learning how to interpret police scanner activity, or simply interested in how police work is conducted on the road. DUI enforcement remains a high priority for most departments, and Code 55 is frequently used during traffic patrols, especially during weekends and holidays, when impaired driving incidents tend to increase.

Code 55 Police is one of the hundreds of specialized police radio codes actively used by law enforcement officers, police dispatchers, and emergency response teams across the country—and even internationally. This specific code is part of a standardized system of numeric codes designed to improve radio communication efficiency and reduce the chance of misunderstanding during high-pressure situations. Code 55 Police specifically refers to an intoxicated driver and is often heard over police scanners, in law enforcement communication, or even referenced in popular police reality shows, documentaries, and crime dramas.
You might come across Code 55 Police while listening to a police scanner app, following a live dispatch feed, or during news broadcasts covering law enforcement activities, especially those involving DUI arrests. These police codes, including Code 55, help officers maintain clear and consistent communication when dealing with sensitive or dangerous situations on the road. The use of such codes helps eliminate ambiguity, allowing multiple agencies to coordinate responses more effectively and efficiently.
To ensure clarity during radio transmission, Code 55 is often spoken by police officers and dispatchers either digit by digit (“five-five”) or phonetically (“code five-five”) depending on department preference and local radio procedures. This practice ensures that the message is transmitted clearly even in environments with static, noise interference, or overlapping transmissions, where a misunderstood code could delay response or cause operational confusion.
The origin of codes like Code 55 Police dates back to the late 1930s. Between 1937 and 1940, the initial set of 10-codes and numerical police signals was developed to streamline communication among emergency services. These codes gained further structure in 1974 when the Association of Public-Safety Communications Officials-International (APCO) officially expanded and standardized the system. This national effort to unify radio traffic terminology played a key role in enhancing law enforcement communication protocols across state lines and agency jurisdictions.
Today, Code 55 and other police codes remain essential tools in the law enforcement community, helping officers communicate faster and more accurately, especially in fast-moving or life-threatening situations. With the continued evolution of police technology and radio systems, many agencies still rely on these traditional codes due to their brevity, clarity, and long-standing recognition within the field.
Police officers rely heavily on a structured communication system when interacting with dispatchers, fellow officers, and other law enforcement personnel. One of the most essential tools in their communication toolkit is the use of police radio codes, such as Code 55 Police, which refers to an intoxicated driver. Also known as 10-55 Police Code, this signal is used during active patrols and traffic stops to report or respond to incidents involving suspected drunk driving. By using concise and standardized codes like Code 55, officers can quickly relay vital information while maintaining efficiency and professionalism in the field.
When a police officer observes a potentially impaired driver—such as one swerving across lanes or ignoring traffic signals—they may report the situation by calling in a “Code 55” over the radio. This alert is transmitted directly to dispatch, the command center responsible for assigning units, monitoring field activity, and coordinating responses. In these high-stakes scenarios, clear communication is critical to ensure the appropriate personnel are sent to the scene promptly to protect public safety and enforce the law.
Code 55 Police doesn’t just serve as a shorthand between an officer and a dispatcher—it also plays a broader role in inter-agency communication. Police codes like this one are regularly used during coordination between uniformed officers, plainclothes detectives, highway patrol units, local jails, correctional facilities, and even emergency medical teams. These codes create a universal language that cuts through potential confusion, especially when multiple agencies are working together in a multi-jurisdictional setting.
The use of 10-codes and police signal codes such as 10-55 helps officers preserve clarity under pressure while minimizing misinterpretation. These codes enable the seamless flow of information, reduce the need for long verbal explanations, and allow officers to maintain operational secrecy when necessary. For example, instead of stating over the radio that a driver appears to be under the influence of alcohol or drugs, the officer simply says “10-55” or “Code 55”, which is instantly understood by all trained personnel.
The standardization of police communication codes, developed initially in the late 1930s and later refined by organizations such as APCO (Association of Public-Safety Communications Officials-International), has enabled law enforcement agencies across the country to maintain order, coordinate effectively, and uphold public safety standards in an increasingly complex environment. Whether responding to a routine traffic stop or a critical incident, these codes are fundamental in supporting the fast-paced and often unpredictable work of modern policing.

It’s just one of many specialized signals in the vast and critical system of police communication codes used every day across the United States and beyond.

What is Code 55 Police?
Code 55 Police is a commonly used law enforcement communication code that signifies an intoxicated driver. Also known in many jurisdictions as 10-55, this police radio code is used by officers, dispatchers, and traffic enforcement units to discreetly communicate that a driver is suspected of being under the influence of alcohol or drugs. The Code 55 Police meaning is vital for ensuring that appropriate action is taken quickly to protect public safety and maintain order on the roads.
When police officers are patrolling highways or city streets and observe signs of impaired driving—such as swerving between lanes, inconsistent speeds, or failure to obey traffic signals—they may call in a Code 55 over their radio. This allows dispatch to alert nearby units or initiate a DUI (driving under the influence) stop, while also documenting the incident in real-time. Using Code 55 Police instead of explicitly saying “intoxicated driver” helps officers maintain concise, confidential, and standardized communication, especially when radio traffic is heavy or urgent.
The 10-55 Police Code is part of a larger system of law enforcement codes developed to streamline communication and minimize misunderstandings during high-stress operations. These numeric codes, often called 10-codes, are used across police departments, sheriff’s offices, and highway patrol agencies nationwide—and in some cases internationally. They were initially introduced in the late 1930s and later standardized by the Association of Public-Safety Communications Officials-International (APCO) in the 1970s.
