Prosecution documents tendered to Dubbo Local Court said a group of girls at school in Gilgandra had been experiencing ongoing difficulties.

The documents said problems of bullying and harassment had started to involve "older female adults" in the town.

Police said the schoolgirl victims were at the stage where they believed they could not walk or drive in Gilgandra without being insulted, harassed or intimidated by Brook Moore "and her cohorts".

Moore, 20, has pleaded not guilty to charges of recklessly driving in a manner dangerous, not keeping left of oncoming motor vehicles, not giving way to pedestrians on a crossing, knowingly driving a vehicle in a manner that menaces others, driving behind another vehicle too closely to stop safely, using high beam on a vehicle in front and using a light on a vehicle likely to dazzle.

Moore appeared before Magistrate Andrew Eckhold this week seeking variations to her bail conditions.

The court was told Moore had moved to a new address and wanted permission to drive to Dubbo to attend antenatal appointments.

Court documents said the father of Moore's unborn child was in custody.

The documents said Moore was unemployed, not studying and well-known to police for driving complaints.

Since February she is alleged to have driven a vehicle "on a regular basis" in a manner that has intimidated and scared the teenage victims and their friends.

"She often swerves her vehicle into the direct path of the oncoming victims and accelerates," police facts alleged.

"She speeds up her vehicle behind vehicles driven by victims, driving at unsafe close distances and using high beam against the victims."

Moore is alleged to have driven recklessly in Miller Street and knowingly driven in a manner that menaced in Warren Road, Railway Street and Hargraves Lane.

Prosecution documents allege a white Holden Commodore driven by Moore had not kept left of oncoming traffic and failed to give way on a pedestrian crossing.

Police allege pedestrians in Gilgandra's main street needed to run from the path of a vehicle driven by Moore on February 16.

She is alleged to have accelerated over a driving line with half her vehicle on the incorrect side of the roadway.

The teenage victim travelling in another vehicle is alleged to have been forced to brake sharply and swerve to avoid a collision with Moore's vehicle and pedestrians.

Moore is alleged to have driven in a menacing manner on February 22, driving close to another vehicle and activating high beam four times, blinding a driver.

Court documents said the victims were scared and feared Moore was trying to pull them over to initiate a fight.

Moore is alleged to have followed a vehicle, her passengers are alleged to have "death stared" victims.

Obscenities are alleged to have been yelled.

The court heard a bail variation application (seeking approval for Moore to drive to antenatal sessions) had been adjourned to give Moore time to obtain a letter confirming details of scheduled medical appointments.

Police opposed allowing Moore to occupy a driver's seat.

"She lives with her parents," the prosecutor said.

"They could assist with transport (from Gilgandra to Dubbo)."

An Aboriginal Legal Service solicitor said Moore's parents worked full-time and the appointments were in the middle of the day.

After considering submissions Magistrate Eckhold said Moore would be allowed to drive to Dubbo if she carried a letter saying the purpose of the journey was to attend antenatal care.

The charges were adjourned to May 12.
