The New South Wales RTA has confirmed that its fixed digital speed camera on the Kingsway at Miranda incorrectly photographed motorists passing through a school zone outside of the zone's speed-limited hours.
"Last week the RTA detected a timing error at the school zone speed camera, affecting speeding offences from May 23 to June 11 inclusive," the RTA said on Friday.
"The timer on the school zone speed camera was out of sync due to a software error, which meant some motorists were being incorrectly detected for speeding."
With some 380 penalty notices issued, the total fine amount is understood to be worth about $49,000.
The RTA has confirmed that the fine amounts will be returned to the affected motorists, with the relevant demerit points wiped from their licences.
