A driver's license is an official document that permits an individual to operate a motor vehicle on public roads. It is issued by a government authority, typically after the applicant passes a written test, a vision test, and a driving skills test. The license includes personal information such as the driver's name, address, date of birth, and a photograph. In many countries, a driver's license also serves as a form of identification. It is important for legal purposes, such as verifying age or identity, and is often required for activities like renting a car or opening a bank account.
