I propose to take Questions Nos. 2203 to 2205, inclusive, together.
The Traffic Signs Manual constitutes a Ministerial Direction to road authorities under section 95(16) of the Road Traffic Act 1961, and is available from my Department's website.
The Traffic Signs Manual stipulates the traffic signs to be used on Irish roads, their layout and symbols, the circumstances in which each sign should be used and the rules for positioning them.
Chapter 8 of the Traffic Signs Manual details the requirements for Temporary Traffic Measures and Signs for Roadworks. These requirements vary depending on the category of road and speed limits in place.
In addition operators carrying out works of this nature are required to comply with relevant Health and Safety requirements. Where the public have concerns regarding safety or other matters they should bring them to the attention of the relevant Local Authority or the Gardaí as appropriate.
