SA drug-driver arrested twice in one day

A South Australian woman has been arrested twice in one day after she allegedly ignored a driving ban while on drugs.

The 52-year-old tested positive to drug-driving at Kadina on the Yorke Peninsula on Sunday morning and was instructed not to drive for 24 hours, police say.

She was caught driving an hour later and was arrested, only to be caught driving again two hours later in nearby Snowtown while on bail.

The woman, who has allegedly not held a licence since 2008, was arrested again and will face court in February on multiple charges.
