Michigan v. Long, 463 U.S. 1032 (1983), was a decision by the United States Supreme Court that extended Terry v. Ohio, 392 U.S. 1 (1968) to allow searches of car compartments during a stop with reasonable suspicion.

David Long was questioned by police after driving his car off a road and into a shallow ditch in Barry County, Michigan.

Long argued during his trial that the evidence found in his car should be suppressed because the search was unconstitutional.

Apart from two citations to the Michigan Constitution, the state court relied exclusively on its understanding of federal law.

In this way, state courts can protect individual rights at a very high level as the late Justice Brennan suggested.

Although this opinion helped clarify what had theretofore been ambiguous, some critics charged that Michigan v. Long was politically motivated.
