Step-by-step explanation:
In Terry v. Ohio and Pennsylvania v. Mimms, the Supreme Court firmly established that an officer who makes a lawful traffic stop and who has reasonable suspicion for the safety of the officer and everyone else on scene.
This means that the officer must have a legitimate reason to suspect that the stopped individual has committed or is about to commit a crime. If the officer reasonably believes that the individual may be armed and dangerous, they are allowed to frisk the suspect for weapons without violating the Fourth Amendment. These decisions by the Supreme Court ensure that law enforcement officers can take the necessary measures to ensure their safety during traffic stops.
