Nick Schemanoff was left at the side of the road for two hours for paramedics reached him
Witnesses expressed their horror after the male motorcyclist was left untreated by paramedics after the Good Friday crash – as there were no ambulances available.
The victim was involved in a collision with a car on the A390 in Tavistock, Devon, at about 10.50am on Good Friday and appeared to have suffered serious injuries.
Paramedics arrived at around 12.45pm – just under two hours later – and he was eventually flown to Derriford Hospital via air ambulance.
Local resident Nick Schemanoff said it was "disgusting" that the biker was left for so long.
He said: "He was lying in the road and looked seriously hurt.
"A local doctor and my neighbour who is an IC [intensive care] nurse were treating him and put him on a neck brace.
The injured man had to flown to hospital in an air ambulance
"Another doctor who was driving past also helped.
It's disgusting that it took so long for the paramedics to get here

The South Western Ambulance Service Trust said it made more staff and vehicles available to combat the increased demand over the Bank Holiday weekend but said that emergency calls were significantly up from last year.

Ken Wenman, the Chief Executive of SWASFT, said: "With extra staff on duty, round the clock, we're ready but the truth is we have a finite number of ambulances and highly-trained staff available.
"This means we will, as always, prioritise and focus on those patients in a time-critical life-threatening condition."
