North Las Vegas Police Department 400 Codes Practice Test

In this code system, each label corresponds to a specific type of call or situation. When a vehicle is observed in a location or in a way that raises concern—unusual parking, occupants acting suspiciously, or any behavior that suggests potential risk—the appropriate code is the one that literally names the scenario: Suspicious Vehicle. Using this label helps dispatch and responding officers quickly understand that the concern is vehicle-related and warrants observation, possible follow-up, or a safety check.

The other options describe entirely different situations: one is about a homicide, another indicates you need to contact a person for information, and the last covers abuse or neglect. Those are separate codes and don’t match a vehicle-specific concern, so the correct code for this scenario is the one that explicitly states Suspicious Vehicle.
