10-97 stands for Check signal, a police code abbreviation.
APCO code for a test or signal check. Several agencies, including the California Highway Patrol, use 10-97 instead to mean arrived at scene.
Example: CHP unit 22-12 is 10-97 at the collision.
Usage notes
The CHP meaning is widely heard on California scanners. This variation shows why radio users must know their own agency's list. Plain-language "on scene" avoids confusion.
