Question to the Home Office:

To ask Her Majesty's Government what assessment they have made of (1) reports of a significant reduction in (a) the number of traffic cameras in active use, and (b) the number of breathalyser tests administered, in the last five years; and (2) the relationship between any such changes and an increase in road traffic accidents.

How police use speed cameras and administer breathalysers is an operational matter for Chief Constables and Police and Crime Commissioners. Police use their professional judgement and discretion as to what they consider most effective, taking into account the specific local problems and demands with which they are faced.

There may be several reasons why the number of breathalyser tests administered has reduced, including drivers being more aware of the law or police deciding to prosecute drivers under more serious offences.

The Government has not conducted an assessment of the relationship between any such changes in the number of traffic cameras in active use or in the number of breathalyser tests administered, and the number of road traffic accidents.
