Coming of age
In the United States, teenagers are allowed to drive at 16 in all states except New Jersey, which requires drivers to be 17 and older, and sometimes receive the responsibility of owning their own car. Teenagers may drive at age 15 in Idaho and Montana. At 16, teenagers are also old enough to donate blood and work in most establishments. At 18 one is legally considered an adult and can vote and join the military. The legal age for purchasing and consuming alcohol and recreational marijuana, the latter of which is only legal in the District of Columbia, Colorado, Oregon, Washington, California, Hawaii, Massachusetts, Nevada, and Alaska, is 21. The legal age for purchasing and consuming tobacco products is 18 in most states; 19 in Alabama, Alaska and Utah; and 21 in California, New Jersey, Oregon, Hawaii and Maine. Multiple localities have also raised the minimum purchase age independent of state laws.
Age of consent reform
Prior to 1981 Wisconsin had an exception to the law that allowed adults who were guilty of sex with minors 15 or older to use as a defense that the victim understood the nature of the sexual act, but there was a rebuttable presumption in Wisconsin that minors under the age of 18 were not capable of informed consent to sex, but as stated, this could be argued against by the defendant in the court of law if the minor was 15 years of age or older. In 1981 the age of consent was lowered from 18 to 16 in Wisconsin, but at the same time it was made an automatic felony to have sex with anyone under 16, informed consent for a 15-year-old was no longer a defense an adult defendant could use in court. In 1983 the age of consent in Wisconsin was raised from 16 to 18, under the new law sex with a minor 16 or older carried the lesser penalty of a Class A Misdemeanor. A marital exemption was included in the law for an adult who was married to a minor 16 or older, but no close-in-age exception was.
