If you're prepared to cop a fine.
The legislation in most states says that you're required to ignore other traffic rules if it is safe to do so. The emphasis is on the 'safe to do so' so pulling over into a no stopping zone or bus lane is generally safe. Running a red is not.

Traffic Support Superintendent Mark Fairney said Mr MacDonald did not have a specific exemption, as emergency vehicles have (police, fire and ambulance), and so did not have any legal standing in disobeying the traffic light.

"Motorists have an obligation to give way to emergency vehicles but they also have an obligation to drive with due care and abide by the traffic laws," Mr Fairney said. "The driver in these circumstances would have a series of different options they could have considered.

"Disobeying the red traffic light is fraught with danger.

"A better option would be to wait until the traffic light changes to green and then provide a safe passage for the ambulance by moving out of its path in the safest way possible."

SA Ambulance Service chief executive Ray Creen agreed motorists should never risk their safety to accommodate ambulances.

"Whilst it was vital motorists do their very best to make a clear passage for an emergency vehicle driving with lights and sirens, we do not encourage motorists to break the law to get out of our way," he said.

"This includes driving at excessive speeds or running a red light. These are obviously dangerous things to do as they put both the driver and other motorists at risk."
