§ John ThursoTo ask the Secretary of State for Transport what percentage of the(a) motorway and (b) dual carriage network has raised central reservation barriers to eliminate the glare of headlights from oncoming traffic. [149708]
§ Mr. JamiesonThere are no recorded examples on the English dual carriageway trunk road or motorway network where the central reserve barriers have been raised to eliminate the glare of headlights from oncoming traffic.
A trial of an anti-glare device attached to central reservation barrier has been undertaken on an English motorway but this proved to be ineffective in reducing accidents.
