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.
Learner's permit
In many states the period of driving on a learner's permit is shortened if the applicant is above the age of eighteen. For example, in Oklahoma if a driver is 18 or older a learner's permit must only be held for one month before the driver qualifies for an intermediate license. Some states allow drivers over the age of twenty-one to bypass the entire graduated licensing process. For example, in Colorado, a driver over the age of twenty-one may apply for and pass the tests for a permit and a full driver's license on the same day and, if successful in passing the tests, may obtain a full driver's license as soon as the driver passes a scheduled driving test.
