Ms Noirín O'Sullivan:

In terms of blood alcohol count, as I said at the outset, sometimes it can be difficult, particularly if people have been fatally injured in road collisions or require medical intervention very early on. That is a priority. Research is done by the Medical Research Bureau, also which has responsibility for analysing the blood alcohol content of samples. As Mr. O'Donohue has said, we see that speed is cause of many fatal road collisions and serious injury collisions; also, non-wearing of seat belts and the use of mobile phones. Coming into the autumn period, there is a lack of awareness by pedestrians in terms of dark clothing and stepping off footpaths. Sometimes cyclists wear earphones and iPods. There are many causation effects other than blood alcohol content, but that is being monitored.
