That's half the problem now. People from overseas who can drive for a minimum of 12 months on their foreign licences before they need to apply for a UK licence. People from EU countries can drive forever on their licence without taking any test whatsoever.When I moved here I had a licence from a British Territory but couldn't just exchange it for a Uk one and had to do all the tests. There was a list of countries that could exchange their licence directly and one of them was South Korea. I have spent a lot of time working in Korea and can say without question that they should never be allowed on the road without a test.
