To ask the Secretary of State for Transport pursuant to the answer of 13 March 2009, Official Report, column 806W, on motor vehicles: testing, what checkpoint sites are used by the Vehicle and Operator Services Agency. (269002)

As previously mentioned in my answer of 13 March 2009, the Vehicle and Operator Services Agency (VOSA) uses over 1,000 checkpoint sites. Some of these sites are temporary and some are permanent. A list of the permanent sites has been placed in the Libraries of the House. VOSA wishes to withhold the list of temporary sites as this information would affect the level of enforcement of non-compliant operators if it became available.
