Question to the Department for Transport:

To ask the Secretary of State for Transport, if he will provide guidance to police authorities who close a road following a road traffic accident about the need to post diversion signs to facilitate traffic flow; and if he will make a statement.

Guidance on traffic management, including the provision of diversion signs, following a road traffic accident or in other emergency situations is already provided in The Traffic Signs Manual Chapter 8. This document, published by the Department for Transport, is available online at: www.gov.uk/government/publications/traffic-signs-manual
