I was not aware of any particular difficulty with the reflective nature of signs that are in place, but I welcome the Deputy's views and will have them tested by the technical experts in my Department. I strongly agree with her view on the importance of signage and road markings in relation to road safety generally. The new road markings and reflective cats' eyes on some of the national primary routes have resulted in a remarkable improvement in motorists' ability to judge positioning on the road and to see oncoming cars etc.
The programme being undertaken by the National Roads Authority is a very important one and the national routes have benefited greatly from it. The upgrading of signage on the N1 was completed last year, the first year of the programme; the N2, the N13, the N14 and the N15 will be completed during this year. It is also expected that the N3, the N4, the N8, the N9, the N10, the N11 and the N25 will be completed by the end of this year. Reflective cats' eyes, even on roads that are not particularly straight, make a remarkable difference to road safety. Somebody said on a national radio programme the other day that I had turned some of the national roads into runways. That is a positive thing.
