What is conveyed by the code 10-66?

The code 10-66 is used to convey the message "Cancel." In law enforcement communication, clarity and brevity are crucial for effective operations, and the 10 Code system helps achieve that. When officers or dispatch use 10-66, they clearly and succinctly express the need to cancel a previous directive or request, reducing the potential for confusion during radio transmissions.

Using 10-66 helps maintain the flow of communication, ensuring that everyone involved understands that a certain action is no longer necessary or relevant. This type of code is essential in fast-paced environments where timely and clear communication is vital for officer safety and operational efficiency. Therefore, it is crucial for officers and dispatchers to be familiar with this code to avoid miscommunication during critical situations.
