Very unfortunately incident
I originally assumed that the Honda had lost it going through Kesselchen and hit the other tourist driver's stationary car (from a smaller scrape) which the marshals were tending to. I didn't realise it hit the Ring safety vehicle.
Hope the two marshals injured make a full and swift recovery. This is the kind of incident that could force the Ring's operators to review potential problems like this..... apparently (from what I read) previous working yellow light was before Breidscheid so no wonder the drivers had picked up the pace again assuming the track was clear. Read that the yellow light just before Bergwerk wasn't working??
