Three people, all from separate vehicles, were pronounced dead at the scene.
A Hampshire Police spokesman said a woman aged in her 20s from Portsmouth, a woman in her 50s from Southampton, and a man in his 30s from Southampton died.
The driver of the HGV, a 38-year-old man from Donnington, Shropshire, was arrested on suspicion of driving a vehicle while unfit through drugs and causing death by dangerous driving. He has been released under investigation while police enquiries continue.
Senior investigating officer DC Cate Paling said: “We are keen to speak with anyone who witnessed the collision, or the moments leading up to it, particularly anyone with dashcam footage.
