A protective sweep is a brief, limited interior search conducted during or immediately after an in-home arrest to protect officers from danger by ensuring no one else who could pose a threat is hidden inside. It focuses on safety and is limited to areas where a person could conceal themselves, not a general search for evidence. The scenario described—making a quick look through the home’s rooms to ensure no one else is present—fits this perfectly: it’s a rapid, safety-oriented check of accessible spaces to verify the home is secure. The other options involve searches for evidence or consent and don’t fit the safety-focused, limited nature of a protective sweep: searching a vehicle during a traffic stop is outside the home context; a full home search after an arrest is an expansive evidentiary search requiring proper grounds or warrants; obtaining consent to search relies on voluntary permission rather than officer safety concerns.
