To ask Her Majesty's Government, further to the Written Answer by Earl Attlee on 8 March 2011 (WA 397-8), how many lorries underwent an annual vehicle test in each of 2007, 2008, 2009 and 2010; and how many lorries failed the safety mirror requirements that came into effect in January 2007 and March 2009.
The Vehicle and Operator Services Agency has over 30 different categories for mirror failure items. It is not possible to extract the specific safety mirror category without disproportionate cost being incurred.
However, of the 443,493 heavy goods vehicles annual tests that were carried out in 2009-10, 1.6 per cent was recorded as failed due to a mirror defect.
Mirror failure rates for previous years are not recorded.
