Reported road casualties in Great Britain: quarterly provisional estimates year ending September 2017

There were 1,720 road deaths in the 12 months ending September 2017 – 4% fewer than in the corresponding period ending September 2016.

A total of 27,010 people were killed of seriously injured, but the DfT says this should not be compared to previous years due to changes in the casualty reporting systems used by police forces.

There were 174,510 casualties of all severities – a year-on-year fall of 5%.

Motor traffic levels rose by 1% compared to the period ending September 2016 – meaning that the overall casualty rate per vehicle mile decreased by 5% over the same period.

Between July and September 2017, 450 people were killed in reported road accidents – a decrease of 1% compared to the same period in 2016.
