Buckling up seems to have become a bit of an afterthought for many.
SA Police say they're catching an average 18 motorists a day who aren't wearing a seatbelt.
That's despite stats that show not wearing a seatbelt is one of the leading causes of death and serious injury in motor vehicle collisions.
Occupants are ten times more likely to be killed in a crash than if they were belted up.
They kicked off Operation Belt Up on November 11 and will run that til this Sunday, November 19.
At least 19 people killed in crashes this year weren't wearing theirs.
"It's a terrible toll for their families and the wider community," SA Police Traffic Support Branch Inspector Ben Spencer said.
“Operation Belt Up has been a regular part of the regional road safety campaigns over the last year while Operation Distraction has been run in the metropolitan area.
"This operation is being run statewide due to Police concerns that the wider community needs to be reminded of the importance of not just doing up your own seatbelt, but making sure everyone in the vehicle is buckled up tight."
Preliminary data shows that in the first two days, Operation Belt Up detected 36 motorists or passengers who were not wearing their seatbelt.
Those caught doing the wrong thing can be issued with an expiation notice of $355 plus a $60 Victims of Crime Levy and lose three demerit points.
There's a similar penalty for passengers 16 and over, while the driver can be fined for not ensuring children are correctly belted up.
