According to the latest figures released by the Association of Chief Police Officers, 88,629 motorists were breathalysed during June’s month long drink-drive campaign, a drop of more than 12 per cent on 2009. The fall in breath tests coincided with a 16.63 per cent rise in the number of collisions recorded by police. Motorists under 25 were subjected to 20 per cent fewer tests than during the same period in 2009, while the fall in testing of older drivers was a more modest 5.45 per cent. The number of tests which were positive or where the motorist refused to give a sample fell by just under rive per cent. But the proportion of breathalysed motorists testing positive rose. “Whilst there has been a fall in the number of breath tests carried out in this year’s campaign the increase in the percentage of positive tests shows that we are targeting the offending drivers more effectively,” said Chief Constable Phil Gormley, the country’s top traffic officer.  More
