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.
Car rental
For insurance reasons, some companies stipulate a minimum and/or maximum rental age. In some cases, the minimum age for rental can be as high as 25, even in countries where the minimum legal age to hold a driver's license is much lower, e.g. 14,15,16 or 17 in the United States. It is not uncommon for there to be a young driver surcharge for all drivers aged under 25.
