During a Terry frisk, which part of the vehicle can be searched?

The search conducted during a Terry frisk allows for a limited examination of a person's immediate area and their vehicle if there is a reasonable suspicion that the occupants may be armed and dangerous. In the context of a vehicle, law enforcement officers are permitted to search the entire passenger compartment, including any closed or unlocked containers within it, but not the trunk unless there is additional probable cause.

This is because the primary goal during a Terry frisk is to ensure the safety of the officer and others by checking for weapons. The entire passenger compartment is considered within the immediate control of the occupants, making it justifiable to check all areas that could conceal a weapon. In contrast, limiting the search to specific areas such as the trunk, driver's seat, or glove compartment would not allow officers to fully assess potential risks within the vehicle. Therefore, the correct response accurately reflects the scope of the search authorized under the principles established in Terry v. Ohio.
