Over the next four days, SA Police will be targeting speeding motorists through Operation Safe Speed.
The operation began at 1am today, Monday, August 26 and will finish at midnight on Thursday, August 29.
South Australia Police Superintendent Robert Gray, who is the officer in charge of the Traffic Support Branch, said speed was a factor when it came to road crashes.
"The aim of this operation is for police to influence and educate drivers about speeding," he said.
"Reductions in speed will save lives and minimise injuries."
"We know that vehicles travelling above the posted speed limit are more likely to be involved in a crash and are also more likely to be involved in a serious crash."
Superintendent Gray said the same operation was conducted in March with 911 detections across the state.
"Over the course of this Operation drivers can expect to see a large police presence on our roads, particularly in locations with the highest traffic volumes," he said.
"The road toll is currently at 75 (as of Sunday, August 25) and we, as a police force, cannot stress enough that we need the help and cooperation of the community to reduce the number of lives lost on our roads."
Crash data from 2018 shows that in about 20 per cent of fatal crashes excessive speed was a factor.
Police have stated that reducing the average travel speed by 5pc would reduce rural casualty crashes by 30pc and metropolitan crashes by 25pc.
The risk of a casualty crash almost doubles with every 5km/h speed increase on a 60km/h speed limited road, or with every 10km/h speed increase on 110km/h roads.
