From 1 October 2014 the physical paper "disc" was no longer issued, with enforcement of the taxation now being done through the automatic number plate recognition (ANPR) system. The response to this change has been mixed; A survey in 2016 revealed that 75% of those surveyed wanted tax discs reinstated, while "The Daily Telegraph" reported in November 2017 that road tax evasion had tripled as a result of tax discs no longer being produced. In Germany, a driver is required to carry a vehicle licence (called the "Fahrzeugschein") containing vehicle owner data, technical specifications and car modifications. Additionally, each car has two registration plate stickers, one to confirm the car has been properly registered, and one to indicate it has passed its vehicle inspection ("Hauptuntersuchung" or "HU") and the date by which the next inspection is due. While the vehicle licence and the registration sticker are permanent, the vehicle inspection sticker is renewed after each inspection. In Guernsey road tax and the display of a tax disc was abolished in 2008 when fuel tax was increased by 14p per litre. Vehicles now display an insurance certificate. In Ireland, a tax disc must also be displayed, which is of the same format as that in the UK. However, in addition, a square insurance "disc" must also be displayed to show that the vehicle has the legally required third party insurance. Private cars over 4 years old require a similar format "disc" from the National Car Test service to show roadworthiness. In Malta, tax discs are very similar in appearance to their UK counterparts, and are also required to be visible on the left-hand side of the windscreen. The disc proves that the vehicle has valid insurance, and that it has passed its Vehicle Roadworthiness Test (VRT). In Sri Lanka, a "revenue licence" must be displayed on the vehicle, and is evidence that the necessary vehicle excise duty has been paid for the specific vehicle. It is normally placed on the left side of the windscreen if it is a four-wheeled vehicle. A revenue licence is issued for a period of one year and must be renewed annually, during which an emissions test must be performed.
