In the courtroom, your judge will tell you about the case, then introduce the lawyers and others who are involved in it. You will also take an oath, in which you will promise to answer all questions truthfully.
After you're sworn in, the judge and the lawyers will question you and other members of the panel to find out if you have any knowledge about the case, any personal interest in it, or any feelings that might make it hard for you to be impartial. This questioning process is called voir dire, which means "to speak the truth."
Though some of the questions may seem personal, you should answer them completely and honestly.
Remember: Questions are not asked to embarrass you. They are intended to make sure members of the jury have no opinions or past experiences which might prevent them from making an impartial decision.
