A driver’s license is an official document permitting a specific individual to operate one or more types of motorized vehicles, such as a motorcycle, car, truck, or bus on a public road.
The term driver’s license is American English; the Canadian English equivalent is driver’s licence, and in British English it is driving licence. In this article, the American terminology and spelling is used except where the section refers specifically to British practice. The laws relating to the licensing of drivers vary between jurisdictions. In some jurisdictions, a license is issued after the recipient has passed a driving test, while in others, a person acquires a license before beginning to drive. Different categories of license often exist for different types of motor vehicles, particularly large trucks and passenger vehicles. The difficulty of the driving test varies considerably between jurisdictions, as do factors such as age and the required level of practice.
In some international agreements the wording driver’s permit is used, for instance in the Vienna Convention on Road Traffic.
