The Department as not made any formal assessment of the relationship between (a) changes to the number and funding of reductions to road safety grants and (b) the number of people killed and seriously injured in road traffic accidents between 2010 and 2013. However, the number of people killed in reported road traffic accidents decreased from 1,850 in 2010 to 1,754 in 2012. The number of people seriously injured in reported road traffic accidents in Great Britain increased from 22,660 in 2010 to 23,039 in 2012. The number of casualties in 2010 were affected by heavy snowfall during the year which would led to fewer accidents than might have been expected had the weather been more typical. Statistics for 2013 will be available in June 2014.
