Md. Code, Courts and Judicial Proceedings § 8–305

Whenever a person appears for jury service, a jury commissioner or jury judge:

(1) May require the person to complete, sign, and acknowledge a juror qualification form in the presence of the jury commissioner; and

(2) If, at that time, it seems to the jury commissioner or jury judge to be warranted, may question the person but only as to responses to questions in the form and grounds for disqualification, excusal, exemption, or rescheduling.
