The automaker's in-car cameras will monitor driver behaviour and intervene if it deems it necessary, based on a number of factors.
If the driver looks away - such as instead focusing on a smartphone - or doesn't keep their hands on the wheel, a member of Volvo's on-call assistance team will check in, while drivers not watching the road or having their eyes closed will also be warned.
It's said that under the system - set to roll out to all of Volvo's cars by early 2020 - if they don't respond, the vehicle will slow down and even stop.
Henrik Green, senior vice president for research and development at Volvo Car Group, said in a statement: "When it comes to safety, our aim is to avoid accidents altogether rather than limit the impact when an accident is imminent and unavoidable.
"In this case, cameras will monitor for behavior that may lead to serious injury or death."
Although there have been some criticism of the cameras on the issue of privacy, Volvo has dismissed this by likening it to early backlash over seat belts being introduced in 1959.
A spokesperson also added: "With the cameras, Volvo aims to collect data only in the ambition to make its cars safer and only the data that is required for the systems.
"The cameras will not record video and no data will be gathered without the user's consent. Exact technical setup is yet to be determined."
