Police are targeting people who are using mobile phones while driving during a five-day blitz which will run from Monday, October 21 to Friday, October 25.
As part of Operation Fatal Distraction, SA Police will focus on mobile phone use as well as other driver behaviours which can cause a lapse in concentration.
Officer in Charge of the Traffic Services Branch, Superintendent Robert Gray said the campaign, which began at midnight on Monday, will finish at 11.59 on Friday.
He said any motorist found using a hand held mobile phone, interacting with social media, or showing any other unlawful driver behaviour would run the risk of being issued with an expiation notice during the state-wide blitz.
"Research shows that using a mobile phone while driving increases the risk of crashing by at least four times," he said.
"Distraction is one of the biggest killers of South Australian drivers, and yet there is still a section of our motoring community who are not listening to our warnings.
"If your focus isn't 100 per cent on the road while driving then you're not only being irresponsible, but you're being incredibly selfish.
"Taking your eyes off the road, even for a split second, is a potentially fatal decision."
Police ran a similar operation in August which resulted in 483 expiation notices being issued for distraction based offences.
