A woman has been charged three times this week for driving on drugs, with a used syringe allegedly found beside a five-year-old passenger on one occasion.

Northern Territory Police said the 38-year-old was first charged on February 25, after being seen driving a vehicle with extensively damaged panels, a missing door handle, and sharp shards protruding from the right hand mirror and bumper.

A roadside drug analysis then returned a positive reading for methamphetamine.

Police said they then searched the vehicle and found a used syringe next to a five-year-old passenger.

The woman was arrested and taken to Katherine Police Station, and is awaiting the results of further testing after that incident.

She was charged again on February 28, after being spotted allegedly driving the same vehicle in the wrong direction down a one-way street.

Police said she returned a positive result for cannabis.

Yesterday, police again arrested the woman after she was seen in a different vehicle and tested positive for amphetamine and cannabis.

During the course of the week she was charged with 17 separate offences, including driving without L-plates, driving with a child unrestrained and driving while disqualified.

The woman was remanded in custody and issued with an immediate licence suspension.

She is due to appear in Katherine Local Court on Monday.

Sergeant Ian Kennon said the actions of the woman were extremely disappointing.

"This woman put the lives of herself and others at risk not once but three times," he said.

"She clearly has not learned her lesson based on her actions.

"Anyone disobeying the law can expect to suffer the consequences each time."

In 2018, 50 people died on Territory roads, making it the deadliest patch in Australia.

The Territory road toll for 2019 currently stands at six.
