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.
Youth
The legal working age is the minimum age required by law for a person to work, in each country or jurisdiction. The threshold of adulthood, or "the age of majority" as recognized or declared in law in most countries has been set at age 18. Some types of labor are commonly prohibited even for those above the working age, if they have not reached yet the age of majority. Activities that are dangerous, harmful to the health or that may affect the morals of minors fall into this category.
