Question to the Department for Transport:

To ask the Secretary of State for Transport, what proportion of i) truck stops and ii) Motorway service areas have received any non self-certified security accreditation.

The Government does not operate a mandated or voluntary lorry parking security accreditation system. Trucks stops and Motorway Service Areas set their own security standards unless they voluntarily join a private accreditation scheme. Therefore, the Department for Transport does not hold this information.
