A provisional licence holder has been issued with more than $2000 in fines after police discovered four children travelling unrestrained in her vehicle during a routine traffic stop.

Officers pulled over the 23-year-old woman on Coolah Street at approximately 4:30pm on Monday, October 6, for a random breath test.

During their inspection of the vehicle, police observed four child passengers who were not properly restrained.

According to police, two of the children were not seated in child restraint seats at all, while the other two were seated in appropriate child seats but were not correctly fastened.

Police also allege the woman failed to display P-plates on her vehicle, despite holding a provisional licence.

The driver received three separate infringement notices. The most substantial penalty was for driving with four or more passengers whose seatbelts or restraints were not properly adjusted or fastened, carrying a fine of $1784 and the loss of six demerit points.

She was also fined $330 and lost two demerit points for failing to comply with P2 licence conditions and not displaying P-plates. An additional $140 fine was issued for using a light vehicle that did not comply with standards.

The combined penalties total $2254 in fines and eight demerit points.

The incident highlights the serious consequences of failing to properly secure child passengers, with NSW road rules requiring children to be restrained in age-appropriate child seats or booster seats based on their age and size.
