on probation do you have to be read your miranda rights?

Technically, law enforcement officers do not ever have to read you your Miranda rights.  You read that correctly. The situation where Miranda warnings are important is when the defendant makes statements, and law enforcement tries to use those statements against the defendant in court.  Typically, Miranda warnings should be read when the individual is arrested, otherwise subsequent statements by the defendant can be excluded.    THUS, if you made incriminating statements during this incident, there is a possibility that those statements could be suppressed, if the government tried to use them against you.
