To ask the Secretary of State for Transport at how many road junctions secondary traffic signals have been removed, pursuant to his departmental advice note TA/18/81; what extension of this scheme is proposed; and if he will make a statement.

It is for individual highway authorities to decide on the layouts of their traffic signals. The information requested is not available centrally. The Traffic Signs Regulations and General Directions 1981 define the essential requirements and these are supplemented by departmental advice. There are no plans to revise departmental advice note TA/18/81 in respect of the provision of secondary signals.
