(a) The arresting law enforcement agency shall provide a qualified interpreter to any hearing impaired person whenever the hearing impaired person is taken into custody for allegedly violating any criminal law or ordinance of the state or any political subdivision thereof.

(b)(1) Except as provided in paragraph (2) of this subsection, the law enforcement agency shall immediately request a qualified interpreter from the department, and the department shall provide a qualified interpreter. No interrogation, warning, informing of rights, taking of statements, or other investigatory procedures shall be undertaken until a qualified interpreter has been provided; and no answer, statement, admission, or other evidence acquired from the hearing impaired person shall be admissible in any criminal or quasi-criminal proceeding unless such was knowingly and voluntarily given through and in the presence of a qualified interpreter. No hearing impaired person who has been taken into custody and who is otherwise eligible for release shall be detained because of the unavailability of a qualified interpreter.

(2) If a qualified interpreter is not available one hour after the hearing impaired person has been taken into custody and a request has been forwarded to the department, the arresting officer may interrogate or take a statement from such person, provided that such interrogation and answers thereto shall be in writing and shall be preserved and turned over to the court in the event such person is tried for the alleged offense.
