A woman has been arrested in Sydney’s west after allegedly drink driving with her children in the car.

According to police, the 40-year-old was pulled over on Moxhams Road at Northmead at about 10.30 last night “due to her manner of driving”.

The woman had her two children, aged five and seven, in the car with her and failed a roadside breath test.

She was arrested and taken to Parramatta Police Station where she allegedly blew almost three times the legal limit, a reading of 0.136.

The woman has been charged with mid-range drink driving and had her license suspended immediately.

Family and Community Services have been notified about the incident.

The mother will face court next month.
