The Motor Sports Association has launched an investigation in partnership with the FIA into the British Formula 4 accident that left Billy Monger with life-changing injuries.
JHR Developments driver Monger, 17, lost both lower legs when he collided with Patrik Pasma at Donington Park in the third F4 race on April 16.
The series is backed by the FIA and an investigation into the crash is now underway.
No further details will be released until it is complete.
In a statement, the MSA said: “The Motor Sports Association is investigating the F4 British Championship incident at Donington Park that left Billy Monger with life-changing injuries.
“This investigation is ongoing with the support of the world governing body for motorsport, the FIA.
“Until this investigation is concluded, there can be no further comment regarding the specifics of the incident.
“The thoughts of all at the MSA are with Billy and his family at this difficult time, and it has been incredible to see the extraordinary outpouring of support from the motorsport community.”
As a result of the crash, Monger’s right leg was amputated just below his knee, while his left leg was amputated further up his thigh.
He remains in hospital in Nottingham and has had surgery each day since the crash.
Despite Monger’s injuries, JHR team boss Steven Hunter says he is incredibly positive about the situation.
“He’s doing really, really well – it’s awe-inspiring how positive he is,” Hunter told Autosport.
“He has been going for surgery every day but his attitude has been so positive and his Mum has never left his side, she’s been such a pillar of strength and love.”
A crowdfunding campaign set-up by Hunter and JHR driver coach Tom Ingram has so far raised £750,000 to help Monger with his rehabilitation.
“We knew we would get a good response as it really touched people’s hearts because of how it came about, but not as good as that though,” British Touring Car points leader Ingram told Autosport.
“When I set the target [£260,000] I thought it was a bit ambitious so to have exceeded it by that amount is mental.
“It just goes to show what everyone thinks of Billy and is testament to how well loved he is.”
