Question to the Department for Transport:

To ask the Secretary of State for Transport, what data her Department holds on the number of people screened for drink-driving with a breath alcohol content of (i) 9–21, (ii) 22–34 and (iii) higher than 35 microgrammes of alcohol per 100 millilitres of breath.

Data on screening test results in England and Wales, including the concentrations of alcohol detected in drivers’ breath in roadside breath tests, are published in table RAS2042. The table has not been updated for 2023, so the latest data currently available are for 2022.

The table is available on GOV.UK at: https://www.gov.uk/government/statistical-data-sets/reported-road-accidents-vehicles-and-casualties-tables-for-great-britain#ras20

The Home Office publishes annual statistics on roadside breath tests for alcohol in England and Wales in its Police powers and procedures: Roads policing release.
