In which scenario is an officer NOT allowed to conduct a body cavity search?

An officer is not allowed to conduct a body cavity search during a routine traffic stop because such searches require a higher legal standard and specific conditions. Body cavity searches are invasive procedures that typically require a warrant or the presence of medical personnel, as they significantly infringe upon an individual's privacy and bodily autonomy. The law mandates that these searches be conducted in a controlled environment, usually by qualified professionals, to ensure the safety and rights of the person being searched. In the context of a routine traffic stop, where the interaction is generally limited in scope and aims, the officer does not have the legal justification necessary to conduct such an intrusive search.
