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.
Graduated driver licensing
Acquiring a learner’s permit typically requires a minimum age and passing vision and knowledge (written) tests. These tests usually assess the participant's knowledge of road signs and how to deal with hypothetical situations (e.g. junctions) while on the road. Parental or guardian permission may be required if below a specified age. Those who hold a learner’s permit must generally drive under the supervision of a licensed driver that is aged 21 or above, not be affected by alcohol or other drugs, and there may be restrictions imposed on maximum speed that a learner driver can drive, the types of road that can be driven, and even on the use of mobile phones (cell phones). There may also be limits imposed on the number of passengers in the vehicle, and learner drivers may be required to be free of moving violations and at-fault accidents or crashes for a minimum period of time before moving to the next stage. In many jurisdictions a learner driver is required to display an L sign clearly on the vehicle to indicate to other road users that training and supervised driving is being undertaken. Learner drivers may also be required to complete a logbook of their driving experience, which must be certified or countersigned by a supervising driver or driver trainer.
