Wayne Peake said selfish drivers dropping children off at Mount St Joseph's Girls High School are causing dangerous conditions for pedestrians and other motorists.
WAYNE Peake is bracing himself for when students return to school after enjoying a brief respite during the summer holidays.
Mr Peake said selfish parents, taking children to Panania's Mount St Joseph's Girls High School from the south on Horsley Road - once they clear the M5 Motorway bridge - divert to the left of the traffic and drive forward as far as they can towards the Beaconsfield roundabout.
"The children leap out, whereupon the parents put on their right blinkers and immediately push back out into the single traffic line they left maybe 30 or 40m earlier," he said.
"In doing so, they co-incidentally promote their cars perhaps 15 or 20 places in the queue."
Mr Peake said this exacerbates existing traffic congestion and increases delays for other drivers.
"It's a rude and arrogant practice - and contravenes the road rules," he said.
Mount St Joseph Milperra assistant principal Stephen Mahoney confirmed that traffic outside the school was "challenging" and that parents faced difficulties at drop-off times.
"Traffic gridlock outside the school is problematic," he said.
"Horsley Road is in an industrial area adjacent to a university and the road is shared by truck drivers and university students and staff as well as parents at peak times.
"Parents picking-up their children using 'kiss n go' have been reminded regularly through school newsletters of the process for this to work most effectively.
"The school has clear procedures in place to ensure the safety of all the students at school pick-up and drop-off times and members of our school community are reminded of this process regularly."
