The 10-85 police code stands for Arrival Delay Due To [Cause], and it’s an important part of law enforcement communication protocols.

Understanding the Meaning Behind the 10-85 Police Code

The 10-85 code plays a crucial role in keeping dispatchers and field units informed. It helps maintain transparency and accurate status updates across all radio transmissions. Instead of officers needing to provide long verbal explanations about why they’re delayed, saying “10-85” followed by the cause (e.g., “10-85, traffic jam”) is far quicker and more effective. This promotes smooth communication, faster decision-making, and enhanced coordination between emergency responders.

Police codes like 10-85 were created to improve the clarity, speed, and efficiency of law enforcement communications. These codes originated in the late 1930s as part of the APCO Ten Signals—a standardized list developed by the Association of Public-Safety Communications Officials-International to streamline messaging and reduce misunderstandings over radio channels.

Why Is the 10-85 Code So Important for Police Communication?

Using the 10-85 police code allows officers to stay focused, minimize radio time, and avoid the kind of miscommunication that can happen in the heat of the moment. In high-pressure situations, being able to indicate an arrival delay concisely helps dispatchers make better decisions about unit coverage and timing. Every second counts in emergency response, and the 10-85 code helps make sure time is used as efficiently as possible.
