To ask the Secretary of State for Transport, in respect of the study commissioned by his Department into the use of interval chevrons on motorways and receipt in 1995 of project report 118 of the Transport Research Laboratory, when Ministers were informed of the results and recommendations of its authors, which recommendations he accepts, what further studies have been carried out, with what results, what steps have been taken to publicise the findings and what action he has taken to authorise their (i) adoption and (ii) additional extensive trials.

TRL report PR118 described the results of trials at two particular sites, and indicated that in certain conditions chevrons could bring benefits. This was further reported in the October 1995 edition of "Traffic Engineering and Control". Opportunity for further trials will depend on the suitability of site conditions. Chevrons would normally have to be installed in tandem with other maintenance operations to avoid unnecessary disruption to traffic. The Highways Agency is in the process of identifying possible monitoring sites.
