Can Police Search Your Car Without a Warrant?

An officer has probable cause that a car holds drugs, but no warrant. Can the car be searched? What about a closed bag in the trunk, a search three days later, or a car that is parked while there is time to get a warrant? We go through four Supreme Court cases in date order: Carroll v. United States (1925), which set the rule; United States v. Ross (1982), on containers inside the car; United States v. Johns (1985), on searching seized packages days later; and Pennsylvania v. Labron (1996), on why no separate emergency is needed. Then a later update from California v. Acevedo, what this means for Texas officers, what to write in the report, common mistakes and a quiz.
