There are more than 2m cars on Irish roads, with many motorists spending two hours a day behind the wheel, clocking up on average of 15,000km a year.
In the series How’s Your Driving?, test drivers are put through their paces while “under the influence” in Garda-supervised and Road Safety Authority-controlled tests to gauge how alcohol and drugs affect driving abilities.
