How often do driving licenses expire in the United Kingdom? (Does it depend on the region? It'll be a Welsh driving license, if that makes any difference.) When I google it, the only information it's really pulling up is information about the licenses expiring when you turn 70. Since the license in question belongs to Jack Harkness, I can certainly make that work, but I'm used to licenses expiring at least every ten years in the United States and I want to make sure it really is different in the UK.
