Republic of Ireland Law Questions Answered by Experts
The answer to your question is:
-> yes, you can drive in the UK on a Lithuan***** *****cence, if you are a visitor;
-> if you intend to become a resident there (for example, if you take up work), then you can drive for up to 3 years after becoming a resident there (normally, the moment you start work). Within these 3 years, but after at least 185 days in the UK, you have to exchange your Lithuan***** *****cence for an UK licence, without an exam. The process is detailed on this page: https://www.gov.uk/exchange-foreign-driving-licence . The fee is GBP 43.
