The Driver and Vehicle Standards Agency (DVSA) collects data on the proportion of vehicles presented for MOT tests that fail, as well as the most common defects that are detected. Last year, 29.9% of vehicles failed their MOT test for ‘major’ or ‘dangerous’ defects, that is, those defects most likely to have an impact on road safety. The MOT test ensures that vehicles with such defects cannot be driven legally, and is an important part of ensuring that vehicles on our roads are safe. The vast majority of road accidents are caused by driver error. Estimates are that only around 2% of accidents are directly caused by mechanical vehicle defects.
