Two ambulance staff escaped unhurt after their vehicle appeared to lose control and crash at a Sheffield roundabout while answering an emergency call.
Witnesses said the Yorkshire Ambulance Service vehicle left the road at the Coisley Hill/A57 Mosborough Parkway roundabout at Normanton Spring, demolishing a lamppost.
A spokeswoman for Yorkshire Ambulance Service NHS Trust said: “One of our ambulances was involved in a road traffic collision on Coisley Hill in Sheffield.
“At the time, the ambulance was responding to an emergency call, using lights and sirens.
“There was no delay in our response to the original 999 call and, thankfully, no-one sustained any injuries or required hospital care.
“We will assist the police with any enquiries regarding this incident.”
The spokeswoman said the ambulance, containing a paramedic and emergency care assistant, was responding to an incident ‘categorised as potentially life-threatening or serious’.
She said there was no delay in the patient receiving treatment as an ambulance clinician in a rapid response vehicle was already at the scene at the time of the collision.
She said: “As soon as we were alerted to the collision another double-crewed ambulance was deployed to the incident.”
The service has launched an investigation into the collision, which happened shortly before 9.30pm on Monday.
