- Where sight lines are particularly poor, such as on a left-hand bend, a duplicate set of signs should be placed on the other side of the single carriageway.
NOTE: Details of the traffic management associated with traffic control on a single carriageway road are dealt with in Sections D5.4 to D5.16. Cone spacing depends on the type of road – see Table A1.3 (Appendix 1).
