Reliant Robin was quoted to give 60 to 100 mpg. Licence requirements Despite its size, by being a three-wheeler with an official mass below , the Robin could traditionally be driven by holders of a B1 category driving licence in the United Kingdom, and registered and taxed at motorcycle rates, which gave a saving of £55 a year over a conventional car. Up until 2001, the B1 licence entitlement was given to those who passed the category A motorcycle test, leading to the common misconception that people could drive a Robin on a motorcycle licence. Those passing their motorcycle test after 2001 could not drive a Robin, until the law changed in December 2012. As of 29 December 2012, tricycles such as the Robin no longer fall within the B1 category licence; in-line with European Union law, tricycles are now classified under the category A "motorcycle licence". As such, any person holding a "full motorcycle licence" may legally drive a Robin. As it was not the licence entitlement that changed, but rather the categorisation of tricycles into an existing category, the change applies to all holders of category A motorcycle licences, whenever they were obtained. Shortly after this an oversight was that a person with a full car licence could no longer drive a three-wheeled vehicle; this was then altered by the UK government after car companies which produce three-wheeled vehicles (such as Morgan) protested over the licensing changes, this resulted in car licence holders now being able to drive a three-wheeled vehicle, but an age limit of 21 was also added; this 21 or over age limit also applies to motorcycle category A licence holders. Driving a Reliant with a motorcycle licence (United Kingdom regulations) Originally, it was possible to drive a three-wheeled Reliant with a motorcycle permit, as a full motorcycle permit included a B1 class endorsement, which gave a driver the right to drive vehicles with three or four wheels of up to 550 kg. However, the DVLA ceased to issue the B1 endorsement in 2001. Interest in the Reliant increased once more after January 2013, when the licensing scheme was changed once again. From 2013, a holder of a full category A motorcycle licence over the age of 21 may drive a three-wheeled vehicle of any power. This age restriction applies to full Category B holders also. In a further change in 2014, the UK government
