Those with overseas driving qualifications that are not exchangeable in GB can drive small vehicles (cars up to 3,500kg and motorcycles), provided entitlement is shown on their licence, for 12 months from the date they become resident in GB. During these 12 months, those with overseas driving qualifications are able to retrain for work in the UK. After this time, unless they have a licence from a country designated for driving licence exchange purposes, they are required to take a GB driving test. The 12-month period is a concession that allows drivers who live and regularly drive in GB to continue to do so before having to demonstrate that they comply with the standards that apply to GB licence holders.
