Drug drivers caught near SA schools

Four people have tested positive to drug driving near schools in Adelaide's northern suburbs in the space of a week.

The latest includes a 28-year-old Greenwith man and another man, 32, from Surrey Downs, who tested positive to driving under the influence of methamphetamine in separate areas on Wednesday.

They also face a long list of other driving offences.

Inspector Steve Kameniar said all four positive drug tests were detected during student drop-off times.

Both men received infringement notices and driver direction notices not to drive for 24 hours.
