In what year were police cars first equipped with radio receivers?

• A. 1933
• B. 1949
• C. 1929
• D. 1937

Answer: (C)

The key idea is the introduction of two-way radio in patrol cars, which transformed how officers received and sent dispatch information. In 1929, the first police cars were equipped with radio receivers, allowing officers to hear dispatches and communicate while en route. This enabled faster responses, better coordination, and increased safety compared to relying on calls from the station or returning to base before replying. The later years listed reflect subsequent expansions to more departments, but 1929 marks the initial adoption of in-car radio.
