Investigating officer Det Sgt Mark Dunne, from Thames Valley Police, said: “Although the detection system on the smart motorway was not functioning at the time, other drivers saw the stranded Nissan vehicle and took the necessary evasive action, and we received a number of 999 calls alerting us to the break down in a live lane.
“Tragically, prior to our arrival on scene, O’Sullivan collided with the Nissan, causing a catastrophic injury to Pulvinder.
“Our case was always that the manner of O’Sullivan’s driving was careless, regardless of the status of the smart motorway systems not alerting drivers to the stranded car at the time.
“Pulvinder was a much loved person, and I hope that her family can begin to move forward with their lives in some way now that sentencing has concluded.”
An inquest into Dhillon’s death is expected and O’Sullivan said he would cooperate with that process.
