A license (or permit) is an official document that grants permission to an individual or organization to engage in specific activities. This can include driving a vehicle, operating a business, or practicing a profession. Licenses are typically issued by government authorities and are meant to ensure that individuals meet certain standards and regulations. Licenses often require applicants to complete specific training, pass exams, or meet other criteria. For example, a driver's license allows a person to legally operate a car, while a business license permits a company to conduct operations within a certain area.
