More than half of drivers stopped on suspicion of drug-driving are failing roadside tests for illicit substances, the Daily Mail can reveal today.
According to a survey of police forces, about 60 per cent of suspects were using cocaine, cannabis or other banned highs.
In total, officers have caught more than 3,700 people for drug-driving since the introduction of ‘drugalyser’ testing kits a year ago.
The rate of positive results is far greater than that for drink-driving, with just ten per cent of motorists who take roadside alcohol breath tests found to be over the limit in 2013. Last night, senior police, MPs and road safety campaigners expressed astonishment at figures that reveal the scale of Britain’s hidden drug-driving epidemic.
