A stunning 37 per cent increase in the amount of speeding drivers caught by SAPOL in the regions over the last three financial years has prompted the RAA to call for motorists to be more warey of driving safely.
The figures, obtained by the RAA from SAPOL, show that 21,383 roadside speeding fines were issued by police in the last financial year, up from 18,352 in 2019/20 and 15,560 in 2018/19.
The number motorists who instantly lost their licence for speeding 45km/h or more above the limit on regional roads also surged 20 per cent in the same period, and the total cost of speeding fines increase to $12.6m.
The biggest increases occurred in the Barossa Valley (up 133 per cent) and Mid North and Yorke Peninsula (up 45 per cent), which are among the state's most popular tourist destinations.
RAA Senior Manager Safety and Infrastructure Charles Mountain said motorists ran a greater risk than a fine for exceeding the speed limit.
"Speeding - especially on roads with limits of 90km/h to 110km/h - can have potentially catastrophic consequences for you, your loved ones and other roads users,'' he said.
"Motorists must also adjust their speed accordingly when speed limits change as the they approach towns or roadworks.''
Other dangerous driver behaviour on the increase was overtaking when it was unsafe to do so.
The number of drivers pulled over for this offence increased from 230 in 2018/19, to 243 in 2019/20 and 277 last financial year.
Mr Mountain urged drivers to be patient and concentrate on arriving safely at their destination.
"Drivers should make use of overtaking lanes, and RAA is calling for more of these lanes to be built to in an effort to reduce road trauma,'' he said.
