A Statutory Off-Road Notification (SORN) is a legal declaration made to the Driver and Vehicle Licensing Agency (DVLA) in the United Kingdom, stating that a vehicle will not be used or kept on a public road. This is required by law for any vehicle that is not taxed or insured.
There are a number of reasons why you might need to apply for a SORN. For example, if you are storing your vehicle off-road, or if it is undergoing repairs. You can apply for a SORN online, by post, or by phone. The process is relatively straightforward, and you will need to provide some basic information about your vehicle, such as its registration number and make and model.
