Gregory Presley, Petitioner v. State of Florida, Respondent

Summary

The court held that officers may detain all passengers during a lawful traffic stop for the reasonable duration of the stop without violating the Fourth Amendment. The stop here remained reasonable because it was extended by a passenger's belligerent attempt to leave and the resulting need for backup, not by unreasonable police delay. The court approved the decision below and disapproved contrary state precedent. Justice Pariente concurred in the result but would not have announced a bright-line rule and expressed concern about unrelated questioning of passengers and disproportionate effects on minorities.
