Claims that forcing cars to use sidelights during the day could save hundreds of lives a year appear exaggerated, according to a transport minister.

Studies carried by a Dutch institute suggested the universal use of 'daytime running lights' would cut fatalities on the roads by 17 per cent.

But a review commissioned by the Department for Transport, Local Government and the Regions believes the benefits were overstated because the lights would only help prevent a limited type of accident.

Disclosing the new findings, David Jamieson said the Government would carry out further research.

He was replying to a Commons written question from John Barrett (Lib Dem, Edinburgh W).
