As a citizen of the United States, you have the legal obligation to serve on a jury when called unless you can prove that serving would be a major hardship. Because this duty is expected of you by the government, it's illegal for your employer to fire you or penalize you for serving on a jury. Some states require that you be paid full salary during your absence. The "one­day" system is established in most states so that you are only responsible to be on call for one day unless you're selected to be a member of the jury. Another legal obligation of United States Citizens is to stay at the scene of an auto accident until the law enforcement officials can arrive. Good Samaritan Laws in your state may require you to aid injured people, report accidents or crimes, and do all possible to help the law enforcement officials. You shouldn't ever leave the scene of an accident, regardless of who's to blame. You may face criminal charges if you do. You should remember your right to remain silent, however, and consider talking to an attorney before making any statements to the police. Consult an experienced attorney in your area for more information regarding citizen's duties.
