The Vehicle and Operator Services Agency accident database. Phase IV Final Report

The development of the Vehicle and Operator Services accident database: Phase IV started in September 2008, and ran for a three-year period. The work has built on previous projects which compiled a database of vehicle examinations carried out by the then-existing Vehicle Inspectorate (VI, now the Vehicle and Operator Services Agency – VOSA). The remit for the project was to enter the vehicle defect data gathered by VOSA into a quality-assured database and to undertake analysis of the data to identify where vehicle defects may have had an influence on road safety, and to understand better their specific role in the accidents.
