Almost 20 per cent of drivers tested for drugs in the latest phase of a roadside police blitz returned a positive result, but that was a drop from the results of an earlier stage. Stage three of the breath and drug roadside operation was held between July 15 and 22 across Geraldton and Dongara, with Perth officers targeting thousands of vehicles on each side of the road. A total of 6197 vehicles were stopped during the operation, including heavy haulage vehicles. Out of the 160 vehicles whose drivers were targeted for drug tests, 27 returned a positive swab result and were subsequently charged. That was a strike rate of 16.8 per cent. The positive drug results were higher in the first two phases, at nearly 25 per cent. In the latest blitz, five positive drug results were around Dongara and 22 were around Geraldton. Of the 6000-plus vehicles stopped for driver breath tests, just 18 blew over the limit in Geraldton and one in Dongara. Drug and breath squad Sgt Warren Conder said it was concerning a driver of a larger heavy haulage vehicle returned a positive swab for cannabis. “What is of note is that one for the positive drug tests was a heavy haulage vehicle,” he said. “The results are alarming because Dongara is a retirement town, but people drive through.” Sgt Conder said roadside drug testing was on the rise, not just in metropolitan areas, but in regional WA, too. “I would suggest drivers be cautious of that,” he said. “We will be back in the Mid West soon enough.” Sgt Conder said drug driving led to trauma and road accidents, and reminded the community to report suspicious behaviour to their local station. “If people are aware of drug driving they should report it to police,” he said.
