Holding

The Supreme Court held that Michigan had a "substantial government interest" to advance in stopping drunk driving, and that this technique was rationally related to achieving that goal (though there was some evidence to the contrary). The Court also held that the impact on drivers, such as in delaying them from reaching their destination, was negligible, and that the brief questioning to gain "reasonable suspicion" similarly had a negligible impact on the drivers' Fourth Amendment right from unreasonable search (implying that any more detailed or invasive searches would be treated differently). Applying a balancing test, then, the Court found that the Constitutionality of the search tilted in favor of the government.
