SA Police has suspended the collection of fines for running a red light.

A Supreme Court judgement last week overturned a man's fine for running a red light, after it was found that the camera had not been tested properly.

The red light camera had not been tested while a vehicle actually passed through the intersection during a red light, as required by regulations.

Justice Greg Parker threw out the man’s fine and conviction, leaving police scrambling to ensure other such fines are valid.

Police will now temporarily close 134 red light camera intersections every 28 days so they can be tested.

All fines for running a red light in South Australia that have been issued but not yet paid will not be collected for the time being.

Additionally, Police will issue no new red light fines until it has sought legal advice.

SA Police says having to close intersections every 28 days would cause series obstructions.

“The Supreme Court judgement requires a testing process involving police vehicles activating the red-light camera in controlled conditions,” the statement said.

“This will inevitably cause traffic obstruction, however, this is unavoidable and will be managed as safely as possible to minimise disruption.

“SAPOL will commence the closure of intersections to conduct drive-through tests in accordance with the judgement as soon as possible.”

But the force say it still has “absolute confidence” in its red light camera system.

“However, we acknowledge that as a result of this judgement, we are obliged to review our testing and checking processes while we seek advice in relation to the Supreme Court decision,” the police statement said.

“All unpaid expiation notices issued prior to the judgement on 2 October 2020 and any offences detected from the date of the judgment will be suspended pending the outcome of the advice.”

The SA Government brought in about $13.3 million in fines for drivers failing to obey red and orange lights in the last financial year.
