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:

In APCO 10-codes, 10-80 refers to "Chase in Progress."

This code is used by law enforcement officers to indicate that they are currently involved in a vehicle pursuit or chase, typically involving a suspect trying to evade arrest.
