Which case established that officers cannot search incident to the issuance of a routine citation?

• A. Mapp v. Ohio
• B. Knowles v. Iowa
• C. Terry v. Ohio
• D. United States v. Jones

Answer: (B)

The key idea is that the search incident to arrest rule applies only when a person is in custody because of an arrest. In Knowles v. Iowa, the Supreme Court held that a vehicle search conducted after a driver was issued a routine traffic citation was unconstitutional. Since there was no arrest and the driver was not in custody in the arrestee sense, there’s no justification under the search-incident-to-arrest exception to rummage through the car. The decision emphasizes that allowing searches in routine stops simply to uncover evidence would erode Fourth Amendment protections without the safety or evidentiary justifications that accompany an arrest. Searches may still occur if there’s probable cause, consent, or exigent circumstances, but a routine citation stop does not by itself authorize a vehicle search.
