Emergency services were called to the scene between junctions 8/9 and 10 at 8pm on Saturday (Jan 25) after a grey Peugeot 3008 hit the central reservation, causing it to rebound across the carriageways.
As it crossed the carriageways it hit a silver Volkswagen Passat, and left the road before colliding with trees.
Paramedics went to treat the 32-year-old driver of the Peugeot but he was pronounced dead at the scene.
His next of kin have been notified.
The road was briefly closed to allow specialist officers to carry out an investigation of the scene.
Contact PC Dave Morgan on 101 if you witnessed the collision.
