The Driver's License (USA, Canada) or Driving License (UK, Ireland) is an official document which states that a person may and can drive a motorized vehicle, such as a car on a public road. As most adult citizens in the United States and Canada have a valid driving license, this document is used as a primary form of photo identification in these countries. It is used in different non driving situations where proof of identity or age is required; for example, you will need it for boarding on your airline flights, for purchasing alcoholic beverages, etc.
Laws and regulations about driver's licensing vary between countries, jurisdictions, etc. In most cases it is needed to pass a driving test before getting a Driver's License or a Driving License. The differences are in the age and the required level of practice before getting a license.
