Of the 36,000 drug tests police have administered to NSW drivers in 2015, Insp Blair said almost 12 percent returned positive readings; while an operation in the Shoalhaven, on the NSW south coast, over the weekend netted 27 drug-affected drivers. In August 2014, NSW Roads Minister Duncan Gay said 11 percent of fatalities on NSW roads involved motorists with illicit drugs in their system.
Inspector Steve Blair, commander of the random drug testing unit, would not confirm exactly how many drug testing units would operate in NSW, but said by 2017 there would be "quite a large number out there" that are "portable and can radiate through the state."
Police claim drug driving offences are growing at an alarming rate, but the NSW Council for Civil Liberties does not support the further rollout of roadside drug testing technology. Stephen Blanks, president of the NSWCCL, said the strict liability offence was unfair to drivers.
"The testing only discloses prior drug usage, which may have no adverse impairment of driving ability. Cannabis can hang around in your system for days, maybe even a few weeks, but not have any impact on your ability to drive," he said.
"It is illegal to possess those drugs, but it's never been illegal to take them. It's a small point, but it's worth taking in mind."
Blanks said the absence of any threshold for drug use -- such as the 0.05 BAC for alcohol -- was a major reservation he held about drug testing.
"With alcohol, there is a threshold below which it is recognised that usage doesn't impair ability to drive. With drug tests, there is absolute zero tolerance," he said.
"The problem of drug driving are issues probably not best dealt with through random testing. Perhaps it should be other ways, like driver education or better laws around drug usage or possession. Society would get a better outcome if we took a health and harm minimisation approach, rather than a law enforcement approach."
