Question to the Department for Transport:

To ask the Secretary of State for Transport, what estimate her Department has made of the number of collisions and near misses in the last five years involved drivers with vision below the legal standard.

Data on road injury collisions in Great Britain is reported to the Department by police forces using a data collection system known as STATS19.

STATS19 does not record near misses or identify whether drivers involved in collisions have vision below the legal standard.

Police officers attending collisions can assign a range of factors that in their judgement may have contributed to the collision occurring, including ‘Driver or rider had uncorrected or defective eyesight’. The latest figures are published as part of the Department’s road casualty statistics available from the gov.uk website: https://www.gov.uk/government/statistical-data-sets/reported-road-accidents-vehicles-and-casualties-tables-for-great-britain#factors-contributing-to-collisions-and-casualties-ras07.
