SA Police catch 10,000 drivers on drugs in seven years SOUTH Australian police have detected 10,000 drug drivers since roadside drug testing was introduced seven years ago. Police - who have drug-screened more than 47,000 people a year - say the disturbing figure was reached this month. Acting Assistant Commissioner Michael Cornish says it is a rate "four times greater per 100,000 head of population than any other Australian jurisdiction." Police say the high detection rate also is the result of traffic officers being trained to conduct the tests at any time. Last year, 20 per cent of drivers or riders who died on our roads in South Australia had detectable quantities of illegal drugs in their system,that impair the ability to safely operate a motor vehicle. Illicit drugs impair coordination, reduce reaction time, create poor vision and an inability to judge distance and speed. Drivers thinking of driving drugged better think again; with one of the largest drug driving roadside testing programs in the world right here in your backyard, it's only a matter of time before you get caught.
