The breathalyser a device that measures the amount of alcohol in a person's breath and new laws to tackle drink driving.
The breathalyser has already been in use in the United Kingdom for two years. Gardaí now have the power to make suspected drink drivers breathe into it and, if the crystals turned from yellow to green, bring them to a Garda station where they would be obliged to give a blood or urine sample.
Other measures include a blood alcohol limit of 125 mg. The state pathologist Dr Maurice Hickey estimates a man weighing 11 stones would reach this limit after drinking at least two and three quarter pints or four small whiskeys, but no one knows for sure.
