What does 10-20 convey?

• A. Your vehicle speed.
• B. Your approximate location.
• C. Your current location.
• D. Your communication channel.

Answer: (C)

The main idea being tested is how police radio codes convey where you are. 10-20 is a location code, used to report or request the officer’s whereabouts. That makes the best answer your current location, since the purpose of this code is to communicate exactly where you are at that moment. It isn’t about speed or how you’re communicating (the channel), and while you can provide the best available location if you don’t have a precise fix, the intent is to identify your present position. So when you hear 10-20, think: where am I right now, at this moment.
