When are you supposed to be read your miranda rights

In the case of an arrest, you are supposed to be read your miranda rights. What does this mean? Miranda rights or “Miranda warnings” refer to a warning that is required by law for police in the United States and Canada before they interrogate suspects who have been arrested about their involvement in criminal activity. These protections were established under the 1966 Supreme Court decision in Miranda v. Arizona (384 U.S. 436). The idea behind these requirements was to protect individuals from coercive interrogation tactics and subsequent self-incrimination.”
