Talkback radio ran hot with listeners stating their confusion about when why where it should be school zone time.
2GB's Ben Fordham found out that the RTA advertised twice on 2GB today, the official gazetted start of school zone time this school term.

The two 10 second ads at 8.00am and 3.00 pm, would not be a huge advertising cost when compared to the $6,158,511 in fines collected from one school zone cameras in 1 year at Moore Park Sydney

Flashing lights at school zones are the answer and as the opposition minister for roads Andrew Stoner has been so vocal on the RTA's slow roll out of lights, I'm sure it won't be long that all schools will have them after the March election.
