Whether a lawful custodial arrest of a vehicle occupant permits police to search the automobile's passenger compartment as an incident of the arrest.
Holding
Yes. When police lawfully make a custodial arrest of an automobile occupant, they may contemporaneously search the vehicle's passenger compartment as an incident to that arrest.
Reasoning
Under Chimel v. California, an arrest permits a warrantless search of the arrestee and the area within the arrestee's immediate control to protect officers and prevent the destruction or concealment of evidence. But courts had applied that standard inconsistently when an arrestee had recently exited a vehicle, leaving officers without a predictable rule for roadside arrests.
The Court concluded that articles in the relatively confined passenger compartment of a vehicle are generally within the area from which a recent occupant might reach a weapon or evidentiary item. Treating the passenger compartment as within the arrestee's immediate-control area supplies a workable, readily administered rule while remaining tied to Chimel's search-incident-to-arrest doctrine.
The rule extends only to the passenger compartment, not the trunk. Because Belton's arrest for marihuana possession was lawful, his jacket was in the passenger compartment, and the search followed immediately after the arrest, the search fell within this rule.
