Sergeant Kenny Malaney said: “Although we have spoken to those who stopped to assist, we are still keen to hear from anyone who may have been on the M8 westbound that morning between 1.40am and 1.50am who may have seen the car driving on the road prior to the crash or the collision itself and who has not yet come forward.
“Dashcam video would also be helpful as it may have captured footage that could help our investigation.”
The force said a report will be submitted to the Procurator Fiscal.
