In APCO 10-codes, 10-81 refers to "Breathalyzer Test."
This code is used primarily by law enforcement to indicate that a breath test is being administered to a suspect, usually in relation to driving under the influence (DUI) cases. When an officer communicates a 10-81, it alerts other officers or dispatch that the subject is undergoing a breath alcohol test to determine their blood alcohol content (BAC).
For example, a radio exchange might look like this:
- Unit 2: "Dispatch, we are conducting a 10-81 on the suspect at the scene."
- Dispatcher: "Copy that, Unit 2. Stand by for further instructions."
Using 10-81 helps ensure that all involved parties are aware of the situation, particularly when coordination or assistance might be needed during the testing process.
