A NSW mother was allegedly more than three times over the legal alcohol limit while driving her children to school.

The 41-year-old woman was stopped for a random breath test in the Macarthur Region, southwest of Sydney, shortly after 9am on Friday.

Police say her children, aged 12, 9 and 8, were in the car.

The woman allegedly returned a positive breath test and was taken to the police station where she underwent a breath analysis.

She returned a reading of 0.179, police say.

She is due to face court on June 13 charged with driving with a high range prescribed concentration of alcohol.
