What does 10-28 mean in police radio terminology?

• A. Vehicle registration / license plate.
• B. Check for wants/warrants.
• C. Wanted/stolen.
• D. Emergency response with lights and siren.

Answer: (A)

The main idea here is understanding what 10-28 is used for. This code is the request to obtain vehicle registration information and license plate details from DMV-style databases. When an officer runs a plate, 10-28 signals that the dispatcher or system should pull up the registration status, plate number, and related vehicle details to make sure everything matches official records. This helps confirm the vehicle is properly registered and can reveal mismatches or red flags, such as an expired registration or a plate that doesn’t correspond to the registered owner.

It's not about wants or warrants—that check is associated with a different code—nor does it indicate an emergency response with lights and siren. That’s why the vehicle registration/license plate interpretation is the best fit for this code.
