Amy Jane Harrison, 30, of Sir Neville Howse Place, was caught driving with methamphetamine and cannabis in her system on May 29.

According to information presented to the court, police stopped Harrison in Adina Crescent, where she tested positive to the drugs.

"I used cannabis no more than six hours ago but I haven't had any meth," she said.

Police stopped Harrison again at 10.36am on August 31 at Lucknow after she drove past in a car with a smashed windscreen that was towing a box trailer full of split wood. Her driver's licence had been disqualified for six months on August 3 so she was charged with driving while disqualified during the traffic stop.

Harrison was fined $660 and her driver's licence was disqualified for six months for driving with drugs in her system.

She was fined another $550 for driving while disqualified and she was also disqualified for six months for that offence.
