Accident A55 ??

Hey, anyone see the full sped truck this morning around 8:45 on the approach to the Britannia bridge (A55 near Bangor), from what I could make out it was an Iveco and the front end was missing there didn’t seem to be an accident there and when I passed it, it was moving with the traffic (with his hazards on) but when a friend passed about 5-10 minutes after me he said it was stopped on the side of the road about 100 yards from where I seen him with a car blocking part of the road. Only thing I could think of what happened is that he had an accident earlier on and was trying to get it back to his depot when he broke down but I don’t know, anyone know what was going on?
Thanks.
