Formula One will conduct a thorough investigation of Romain Grosjean's crash at the Brahain Grand Prix.
Grosjean had a miraculous escape from a fiery crash which split his Haas car in two pieces and destroyed a barrier. The French driver said the Halo device, placed on Formula One cars in 2018, had saved his life.
F1 managing director Ross Brawn praised the safety measures taken in recent years but said he was still concerned by the nature of the accident.
"We have to do a very deep analysis of all the events that occurred, because there were a number of things that should not have happened," Brawn said.
