What did the Pennsylvania v. Mimms (1977) case establish?

The Pennsylvania v. Mimms case established that police officers have the authority to order drivers to exit a stopped vehicle during a lawful traffic stop. The Supreme Court ruled that this action is permissible for officer safety and does not violate the Fourth Amendment, which protects against unreasonable searches and seizures. The Court recognized that a police officer's interest in ensuring safety during an encounter with a driver outweighs the driver's interest in remaining in the vehicle. This decision has significant implications for police procedures and traffic stops, as it reinforces the notion that officer safety is a primary concern that can justify certain actions during such encounters.
