When a person is arrested, the officer can search the vehicle as part of the arrest under certain circumstances, but the justification for doing so hinges on the belief that evidence might be present, which is a core requirement for lawful searches. This ensures that the officer's actions are not arbitrary and that there is a legitimate reason tied to the investigation of a crime.
