Ballakermeen High School has issued a reminder to parents as the roads around the school are becoming 'increasingly congested.'
It says that both in the morning and at the end of the school day, drivers are causing blockages.
Parents are asked to avoid the roads immediately next to the site, and drop children at a nearby safe drop-off area.
It adds that the school entrance should also not be used as a short cut through to St Catherine's Drive.
