My first advice would be to contact a lawyer. If you need specific advice for your particular circumstances, you should consult privately with an attorney. Speaking generally, the police are limited when they seek to administer certain types of field sobriety tests. They usually rely on the cooperation and permission of the pulled-over individual when performing these tests. If a person consents, their results will be potentially used against them if charges are filed. Generally speaking, refusing to cooperate with tests is not an "admission of guilt" per-say. There are constitutional protections against self-incrimination. Field tests, for example, are generally less reliable and usually cannot be forced upon a person. However, once the situation escalates to an arrest, the circumstances are different. If a person refuses to take a data-master test at the police station, they risk a serious traffic ticket with huge license sanctions. Further, in certain situations, the police may even be able to obtain a court-order to do a blood draw. Anyone charged with a OUI should consult privately with a lawyer. If they cannot afford to retain a lawyer, the court may appoint them one at the public's expense depending on availability.
