Several marshals and team members were injured in a chaotic DTM race at the Hungaroring on Sunday as heavy rain struck the circuit.
Although the race started in dry conditions, light rain began falling just after the start which gradually became heavier, forcing drivers to pit for wet weather tyres. However the amount of standing water in the pitland, coupled with the low-grip surface, saw several drivers overshoot or altogether miss their pit boxes.
Lucas Auer was the first to stop and as he tried to turn into his pit box his Mercedes didn't comply and hit a number of marshals, one of which sustained "severe leg injuries".
Edoardo Mortara ran into his pit gantry which subsequently fell onto his car and then Bruno Spengler ran into his mechanics, sending a couple of them flying.
A Safety Car was brought out before the race was red-flagged as ambulances made their way into the pitlane to attend to those injured.
A statement from the series said: "An injured marshal has severe leg injuries. Two further people have medium-level injuries.
"None of the injured people is in critical condition, they are all being transported to hospital."
Series boss Gerhard Berger added: "After what has happened today, of course, the sporting side takes a back seat. I wish the injured marshals and mechanics a speedy recovery."
