Question to the Home Office:

To ask the Secretary of State for the Home Department, how many breathalyser tests were carried out across West Mercia in the last 12 months; how many tested positive; and how many resulted in a prosecution.

The Home Office collects and publishes data on roadside breath tests for alcohol as part of its annual ‘Police Powers and Procedures: Roads policing’ statistical release. The latest data is available here Police powers and procedures: Roads policing, to December 2023 - GOV.UK and covers the calendar year ending December 2023.

In 2023, West Mercia Police carried out 7,811 roadside breath tests for alcohol, of which 1,248 were positive or refused.

The Home Office does not hold information on how many of these resulted in a prosecution.
