A woman driving with three unrestrained infants in the car has been arrested by Northern Territory police after testing positive for cannabis.
The 24-year-old was stopped as she was leaving Katherine on the Victoria Highway about 10pm on Wednesday, with three babies aged six weeks, 10 months and 20 months on the back seat.
Police allege they found a quantity of cannabis when they searched the car.
They have fined the woman almost $2000 for driving with unrestrained children, cannabis possession and failing to produce a licence.
Her 22-year-old female passenger was also fined $300 for cannabis possession.
At 11.30pm police pulled over another vehicle on the Stuart Highway, with the 38-year-old male driver testing positive to methamphetamine.
He was arrested to undergo a blood test and disqualified from driving for 24 hours.
The man has been served with a notice to appear in court charged with driving with a prohibited drug in his blood.
The charge carries a maximum penalty of six months imprisonment.
