Facts

Plainclothes policemen patrolling a 'high drug area' in an unmarked vehicle observed a truck driven by petitioner Brown waiting at a stop sign for an unusually long time. The truck then turned suddenly without signaling and sped off at an unreasonable speed. The officers stopped the vehicle, intending to warn the driver about traffic violations, and upon approaching, observed plastic bags of crack cocaine in petitioner Whren's hands. The petitioners were arrested and subsequently moved to suppress the evidence, arguing that the stop was not justified by reasonable suspicion or probable cause.

Issue

Whether the temporary detention of a motorist who the police have probable cause to believe has committed a civil traffic violation is inconsistent with the Fourth Amendment's prohibition against unreasonable seizures unless a reasonable officer would have been motivated to stop the car by a desire to enforce the traffic laws.

Whether the temporary detention of a motorist who the police have probable cause to believe has committed a civil traffic violation is inconsistent with the Fourth Amendment's prohibition against unreasonable seizures unless a reasonable officer would have been motivated to stop the car by a desire to enforce the traffic laws.

Rule

The temporary detention of a motorist upon probable cause to believe that he has violated the traffic laws does not violate the Fourth Amendment's prohibition against unreasonable seizures, even if a reasonable officer would not have stopped the motorist absent some additional law enforcement objective.

The temporary detention of a motorist upon probable cause to believe that he has violated the traffic laws does not violate the Fourth Amendment's prohibition against unreasonable seizures, even if a reasonable officer would not have stopped the motorist absent some additional law enforcement objective.

Analysis

The Court applied the rule by emphasizing that the subjective intentions of the officers do not invalidate a stop that is justified based on probable cause. The Court rejected the petitioners' argument that ulterior motives could invalidate police conduct justified on the basis of probable cause, affirming that the Fourth Amendment's concern with 'reasonableness' allows certain actions to be taken in certain circumstances, regardless of the officers' subjective intent.

Conclusion

The Court affirmed the lower court's decision, concluding that the stop was reasonable under the Fourth Amendment because the officers had probable cause to believe that a traffic violation had occurred.
