SA Police have fined 510 drivers in the first week of Operation Distraction, targeting drivers using mobile phones or not wearing seatbelts.

314 drivers have been reported for using a mobile phone while driving and 196 road users have been ticketed for failing to wear a seatbelt.

Operation Distraction will target distracted drivers during the month of July.

124 of the 196 seatbelt offences were issued on South Australia's rural roads, with police saying rural drivers were taking an even greater risk due to the higher speeds allowed on country roads.

Police were targeting inattention, with recent statistics showing it was a contributing factor in approximately 60 percent of all rear-end collisions.
