If drivers do not change their behaviour and slow down around schools, a tragic crash will happen, police say.
Police in Marlborough will be targeting drivers in an effort to convince people that they must slow down around schools, Acting Area Commander Senior Sergeant Peter Payne said.
"We need this community to step up too."
Over the past two months a speed camera has been set up at the schools where statistics show children were at greatest risk of being severely injured.
In April the speed camera recorded that 13.96 per cent of vehicles passing Spring Creek School were exceeding the speed limit.
