What does 10-50 mean?

• A. All clear; no further assistance needed.
• B. Traffic accident.
• C. Vehicle registration / license plate.
• D. Repeat the last transmission.

Answer: (B)

10-50 signals a traffic accident. In the radio code system, these numbers are used to quickly convey common situations so responders can react fast without long phrases. When someone uses 10-50, it tells dispatch and other units that there’s a crash on the scene, which typically prompts arrival of emergency medical services, traffic control, and possibly a tow, depending on the situation. This helps allocate the right resources and keeps radio traffic efficient. The other options don’t fit because they describe different meanings: all clear or no further assistance isn’t a crash signal, vehicle registration/license plate is a separate type of inquiry, and repeating the last transmission is a different code used to request a resend.
