Mr. John Twomey:

The statistic we gave earlier was that in 2014, one in 475 people tested were positive. In 2005, when mandatory alcohol testing was introduced, the figure was in the region of one in 250 so while the figure has increased, compliance has improved over that period.

I do not have the figures for alcohol testing of HGV drivers but there is some research work on that and we may be able to provide a note to the committee that may be of assistance.
