The following information was requested under the Freedom of Information Act 2000:
Q 1. What are the official Home Office Guidelines in relation to the pre-use checks for a LTI 20-20 speed gun and a ProLaser III speed gun and how should each of them be performed?
Q 2. Have the Home Office or other Authoritative body released or ratified instruction that the checks that were in force on 1 January 2009, 1 January 2010 and 1 January 2011 should be amended?
Q 3. If they have been amended, what are the amendments and on which date were they authorised?
In response, the following information was released on 28 June 2011:
A 1. The Home Office has not issued guidelines for pre-use checks on either the LTI 20.20 range of laser speedmeters or the Prolaser III laser speedmeter. Each police force is free to choose their own pre-use checks, but they would normally follow the manufacturer’s instructions as laid out in the operator’s manual or provided in training sessions. ACPO had issued guidance on the use of speedmeters in the document: ‘ACPO Code of Practice for Operational Use of Road Policing Enforcement Technology’. This guidance has been withdrawn and is currently nearing the end of a review process. The old guidance stated that operators should follow the manufacturer’s instructions for pre- and post-use checks on laser speedmeters.
A 2. The Home Office has not released any instructions concerning the pre-use checks on LTI 20.20 or Prolaser III laser speedmeters. However, the LTI 20.20 Truspeed DC laser speedmeter was type approved on 13th December 2010, and the manufacturer’s instructions would have been available from that date.
A 3. See the previous two responses. No instructions or amendments have been issued by the Home Office about pre-use checks on the LTI 20.20 or Prolaser III laser speedmeters. The Manufacturers, however, have issued user manuals which have remained unaltered since type approval. ACPO has withdrawn the ‘ACPO Code of Practice for Operational Use of Road Policing Enforcement Technology’ and will be issuing a new guidance document. The old document said and the new document is expected to say that operators are best advised to follow the manufacturer’s instructions for pre- and post-use checks.
