It was a motorbike. A flatbed road maintenance lorry was turning right into Bowling Green Lane (coming up towards Mt Pleasant). It looks like the motorbike was trying to overtake as the bike was buried headfirst under the driver's side of the cab. Must have gone in flat as there was only damage to the lower half of the cab door. They were loading the rider into an ambulance when I got there, but it didn't look very hopeful i.e. the ambulance didn't go anywhere. I heard sirens going on about 20 minutes later though, so hopefully he was off to hospital.
I don't think there were any cyclists involved, but I could only see the scene from one side.
One of those look and look again accidents, poor sod and poor driver
