Three people died after a blue Audi Q7 came off the M8 near Junction 31 west of Glasgow just after 5 am on Sunday morning, and it landed flat on its roof.
Two men aged 27 and a third man, 31, were pronounced dead at the scene.
Five others were taken to the hospital.
The crash as of now is largely believed to be a single crash.
A 35-year-old man was arrested on suspicion of road traffic offenses in relation to the crash.
A section of the M8’s westbound carriageway was shut for several hours on Sunday as the investigation into the crash continued.
