Which 10-code indicates that a detainee can speak English?

• A. 10-30
• B. 10-21
• C. 10-23
• D. 10-27

Answer: (A)

Knowing a detainee’s language ability is crucial for clear, safe communication in the field. The language indicator code is a quick radio signal that tells everyone whether you can interview the detainee in English or if an interpreter is needed. The choice that signals English-speaking is used because it immediately communicates that direct English conversation is appropriate, helping you gather information efficiently and reducing the risk of miscommunication. Other codes in the set are used for different needs, such as indicating a language barrier or the need for an interpreter, which is why those do not fit this question.
