Does a K-9 sniff alert provide probable cause to search the occupants of a vehicle?

• A. Yes
• B. No, it only provides probable cause to search the vehicle
• C. Only if dog trained for occupants
• D. Only with occupant consent

Answer: (B)

A trained K-9 sniff alert at a lawful vehicle stop indicates that contraband is likely inside the vehicle, which gives officers probable cause to search the vehicle itself. It does not automatically authorize searching the occupants. To search a person, officers generally need separate probable cause or consent, or apply another permissible justification (like a search incident to arrest or a Terry stop for weapons). So the alert best supports a vehicle search, not a search of the people inside.
