M77 SB accident today

Leaving Glasgow headed south just after 13:00 I hit heavy traffic on the M77 which turned out to be an artic and a car, approx 5 ambulances 3/4 red cars with lights on the roof (fire) a fire engine police as expected, but I couldn’t think what could have happened as every panel on the car looked bashed and the artic was across hard shoulder/lane 1, anyone else see it?
