In the UK, you generally need at least third-party car insurance before driving on public roads, unless the vehicle is declared off the road with a SORN. Driving uninsured can lead to a fixed penalty, penalty points and the vehicle being seized; a court may impose a larger fine or disqualification depending on the circumstances. A gap in cover may also make future insurance quotes more expensive, although each FCA-authorised insurer assesses risk differently. Arrange cover before driving and check the official GOV.UK guidance or speak to an FCA-authorised provider if you are unsure.
