I think the figures are pretty clear. I can give Deputy McConalogue some tables to support them. The figure of 3,003 fixed penalty notices is based on drivers who have been tested by the Medical Bureau of Road Safety, so that figure is incontestable. In terms of drivers who have taken three penalty points plus the €200 fine, the figures show there were 531, 563, 501 and 613 such drivers in 2013, 2014, 2015 and 2016, respectively. There is a gradual trend toward that figure being far too high. Non-specified drivers are a different category. They are learner drivers and people who drive professionally. In that category, the figures for such drivers were 356, 339, 315 and 350 in 2013, 2014, 2015 and 2016, respectively. The total number of drivers arrested on suspicion of intoxicated driving was 7,962, 7,697, 7,419 and 8,063 in 2013, 2014, 2015 and 2016, respectively.

According to the other evidence, when An Garda Síochána stepped up enforcement during the Christmas period, I think the number of arrests for drink-driving increased by 35%.
