434 U.S. 106 (1977)
Pennsylvania v. Mims represents a pivotal moment in the jurisprudence surrounding the Fourth Amendment's protections against unreasonable searches and seizures.
Does ordering a driver out of a vehicle during a valid traffic stop violate the Fourth Amendment's prohibition against unreasonable seizures?
A police officer may, consistent with the Fourth Amendment, order a driver to exit the vehicle during a lawful traffic stop to ensure officer safety.
The Supreme Court held that the officer's order to Mims to exit the vehicle was reasonable and thus did not violate the Fourth Amendment.
Pennsylvania v. Mims is significant as it established clear guidelines for police officers during traffic stops while reaffirming the principle that reasonable police procedures, even with minimal intrusion, are permissible under the Fourth Amendment if justified by a legitimate safety concern. This case is foundational in understanding the breadth of police discretion during roadside encounters, illustrating the Court's prioritization of officer safety in its Fourth Amendment interpretation.
