The purpose of this booklet is to inform young people of their rights when they become 18 and to help them recognize and avoid possible legal problems. Although written specifically for young people in Wisconsin, the booklet can be used by youths in any part of the United States. A summary of legal principles in effect at the time of publication is followed by sections on voting; jury duty; drinking laws; driving; contracts; employment; consumer protection; marriage, divorce, and children; criminal charges; military service; apartments; and credit. The booklet, however, does not offer legal advice, and for answers to specific questions adolescents are asked to check the sources mentioned in the booklet or to talk with a lawyer. A guide to government and community resources in Wisconsin is included. (RM)
