Question to the Department for Transport:

To ask the Secretary of State for Transport, whether he has made an assessment with Cabinet colleagues of the potential impact on economic growth of switching from fixed time to part time signals at roundabouts.

The Department has made no current assessment. Decisions on whether to signalise roundabouts, including whether they operate on a part-time basis, are for traffic authorities at individual locations. I would be happy to discuss specific examples with the Rt Hon. Member.
