Youth
Driving age is the age at which a person can apply for a driver's license. Countries with the lowest driving ages (below 17) are Australia, Canada, El Salvador, Iceland, Israel, Estonia, Macedonia, Malaysia, New Zealand, Norway, the Philippines, Russia, Saudi Arabia, Slovenia, Sweden, the United Kingdom (Mainland) and United States. The Canadian province of Alberta and several U.S. states permit youth driving as low as 14. Niger has the highest minimum driving age in the world at 23. In India, driving is legal after getting a license at the age of 18.
Driver's license
The eligible age to first obtain a driver's license varies substantially from state to state, from 14 years, three months, in South Dakota to 17 in New Jersey. In a majority of states one can obtain a license that allows driving without adult supervision by age 16, after passing the requisite tests. Since the driver's license is a commonplace document that carries much of the necessary information needed for identification, it has become the primary method of identification in the United States.
