asked the Secretary of State for Transport if he will publish in the Official Report, the siting distances of the end of roadworks traffic signs on (a) major roads, (b) minor roads, (c) dual carriageways and (d) motorways.

The general departmental advice for the siting distance of the "end of roadworks" signs is related to the traffic speed of the road. For under 30 mph, 30–50 mph and over 50 mph roads the recommended siting distances are 10–30 metres, 30–45 metres and 45–90 metres respectively. In urban areas the "end of roadworks" sign may be omitted in certain circumstances.

asked the Secretary of State for Transport if he will publish in the Official Report the siting distances and minimum number of traffic signs required in advance of roadworks on (a) major roads, (b) minor roads, (c) dual carriageways and (d) motorways.

There is a statutory requirement to ensure road safety at roadworks, but not to provide a minimum number of traffic signs nor to define the siting distances. My Department has published advice on these matters, principally in the traffic signs manual. As the information in relation to signing in advance of roadworks is rather detailed, I shall write to the hon. Member.
