The 10-55 police code is a commonly used radio signal in law enforcement communication, and it stands for “Intoxicated Driver.” When police officers or dispatchers use the term “10-55” over the radio, it alerts units that there is a driver suspected of being under the influence of alcohol or drugs.

An intoxicated driver can pose a serious risk to others, and responding to a 10-55 situation typically involves traffic stops, field sobriety tests, and potential arrest or detainment. Officers are trained to recognize signs of impaired driving, and the use of the 10-55 police code helps prioritize these dangerous scenarios without causing public alarm.
If you’re researching police codes for scanner listening, law enforcement training, or general knowledge, understanding what 10-55 means is essential. It’s one of many “10 codes” or police radio codes used to streamline communication between dispatchers and law enforcement personnel.
On this page, you’ll find the most updated and accurate information about the 10-55 police code, its meaning, when it’s used, and how it fits into the broader law enforcement code system. Whether you’re looking for police scanner codes, cop codes, or emergency response signals, we offer free resources and detailed explanations for enthusiasts, students, and professionals.
The 10-55 Police Code is one of the many standardized police radio codes used by law enforcement officers not only across the United States but also in various parts of the world. This particular code refers to an intoxicated driver, a serious public safety concern that requires immediate attention from patrol officers and traffic enforcement units. The 10-55 code is part of the broader “10-code” system, which was designed to make radio communication between officers and dispatchers more efficient, discreet, and standardized.
You may hear the 10-55 Police Code mentioned during real-time police scanner transmissions, especially during DUI checkpoints or roadside traffic stops involving suspected impaired drivers. Additionally, this code is frequently referenced in police dramas and reality law enforcement shows aired on popular TV networks, helping viewers understand how law enforcement handles impaired driving incidents in real-world scenarios.
In most professional law enforcement environments, the 10-55 code is articulated digit by digit — “ten fifty-five” — rather than being spoken as a whole number. This practice is crucial for radio clarity and helps avoid miscommunication during high-pressure or noisy field situations. Police officers and dispatchers rely on this precise verbalization to ensure messages are transmitted correctly and understood without confusion or delay.
The 10-code system, including the 10-55 Police Code, was first developed between 1937 and 1940 to provide a unified system for law enforcement communication. Later, in 1974, the system was reviewed and expanded by the Association of Public-Safety Communications Officials-International (APCO). This organization played a key role in standardizing radio traffic across multiple agencies, improving interoperability between departments and emergency response units.
Police officers, sheriffs, and detectives rely heavily on police code communication to streamline operations and ensure quick, accurate responses to emergencies. One of the most commonly used codes is the 10-55 Police Code, which signals an Intoxicated Driver. When this code is transmitted by dispatch, it immediately notifies officers that a potentially impaired driver is on the road—posing a serious threat to public safety and requiring immediate law enforcement attention.
Typically, this kind of communication takes place over two-way police radios, where a dispatcher coordinates officers based on real-time events. Whether it’s a suspected DUI on a city street, a rural highway, or at a checkpoint, the use of radio signals like 10-55 helps law enforcement maintain order and public safety without confusion or delays. Rather than describing a situation in full detail, a brief code like 10-55 transmits the necessary information clearly and efficiently, allowing officers to act quickly.
Beyond just officer-to-dispatch communication, police radio codes—including 10-55—play a vital role in inter-agency collaboration. Officers in the field use them not only to speak with dispatchers but also to coordinate with fellow officers, K-9 units, highway patrol, detectives, and even local jails or emergency medical services. These codes create a universal language within the law enforcement community, improving both communication speed and operational security.
The 10-55 police code is just one example from a larger system of law enforcement shorthand known as ten-codes, originally created to ensure concise communication. Using these codes, departments can report incidents more quickly while minimizing the risk of misinterpretation—especially in high-pressure or life-threatening situations. For intoxicated driving situations specifically, time is critical, and having an established, universally understood code like 10-55 helps police mitigate dangers on the road effectively.
