The South Australian government will consider advice from police on what legislative changes may be needed amid doubts over the operation of red light cameras at more than 100 intersections across Adelaide.
But Premier Steven Marshall has urged people to obey the road laws and take cameras out of the equation after the Supreme Court last week ruled a fine invalid because of the way police tested the devices.
"Police are looking at the most recent case. This is a concern of course," Mr Marshall said.
"My clear message to the people of South Australia is regardless of the action we have had to take in the recent couple of days, we want people to obey all of the road rules.
"We don't want to see people running red lights."
After last week's court ruling, 134 intersections across Adelaide will be closed to allow testing to be conducted.
All unpaid fines issued before the judgement last week and any offences detected since have also been put on hold as police seek legal advice.
The judgement found a 2018 red light camera fine was invalid because, in certifying each camera, police only photographed cars travelling through the intersection on a green light, not a red light.
"The Supreme Court judgement requires a testing process involving police vehicles activating the red light camera in controlled conditions," police said in a statement.
"There are significant challenges in closing intersections to enable police vehicles to activate red light cameras in these circumstances."
Police said it would require multiple officers to safely close and control each intersection during testing.
"This will inevitably cause traffic obstruction however this is unavoidable and will be managed as safely as possible to minimise disruption," the statement said.
Mr Marshall said police were looking at the court decision and considering whether legislative changes were needed and the government would wait on that advice before taking any action.
"Hopefully they will be able to provide some advice to the government very soon," he said.
