Traffic and Highway Patrol Commander, Assistant Commissioner Michael Corboy, said he was flabbergasted at the number of recent reports about people being detected drink driving with young children in the car - including one at Bossley Park earlier this week.
A woman will face court next month on high-range drink driving charges after being involved in a crash with her grandchildren in the car on Mimosa Road on Tuesday.
About 3.30pm, police were waiting to turn left onto Mimosa Road from Polding Street, Bossley Park, when they saw a Corolla collide with a vehicle being driven by a 17-year-old boy.
It will be alleged the Corolla's driver - a 56-year-old woman - left the scene, with police later locating the Corolla in a school zone further along Mimosa Road. The woman drove away from police, but later stopped at a children's crossing and got out of the car.
At the time, police observed an eight-year-old boy and a six-year-old girl in the Corolla. The woman was subjected to a roadside breath test, which returned a positive result.
A subsequent breath analysis returned an alleged reading of 0.167.
She was issued a Field Court Attendance Notice for driving with a high range PCA to attend Fairfield Local Court on Tuesday, July 16.
Child at risk notifications have been made and the children were released into the care of their mother.
Assistant Commissioner Corboy said anecdotally they have noticed many of these incidents taking place around school pick-up time.
"This is simply unacceptable. We know the school run can be stressful, but it is no excuse to get in the car under the influence of alcohol," he said.
"What would you say to other relatives if the youngest members of your family were killed or injured in a crash of your making?
"Children, regardless of whether they are pedestrians or passengers in a car, are our most vulnerable road users."
Assistant Commissioner Corboy called on friends and neighbours to act if they noticed a parent seemed like they shouldn't be driving.
"If you believe they are impaired, speak up and ensure they make arrangements with a friend or another parent to collect the kids from school," he said.
