In January 2005, the Vehicle and Operator Services Agency (VOSA, now the DVSA) introduced a computerised system for reporting the MOT (roadworthiness) test results, which was fully implemented by the beginning of April 2006. In November 2010, an anonymised version of the dataset was made publicly available, and there have been subsequent data releases since that time. The scoping study identified the value of obtaining additional information from vehicle licensing statistics collected by the Driver & Vehicle Licensing Agency (DVLA), which could be used in conjunction with the MOT data to generate an enhanced dataset. After a successful data application to DVLA, an enhanced version of the dataset was received by the project team in July 2015, with a number of further updates since then. The primary aim of the work is to explore the potential for this dataset to inform our understanding of car ownership and use, and related issues such as energy consumption, air pollution and climate change emissions from vehicle use.
