Daniel Ricciardo has reportedly undergone treatment in hospital after a motorbike accident in Queensland.

The retired Formula 1 star has been back in Australia and made a rare public appearance last week, speaking at a conference about moving on from his “crazy, high-speed life” in the sport.

But a run on a dirt bike earlier this week seemingly went wrong.

Ricciardo was riding outside Cairns when he crashed and suffered a collarbone injury, according to PlanetF1.

The report said he was taken to Mossman Hospital.

“While details are scant at present, Ricciardo is understood to have been in good spirits while being treated for his injury,” it said.

Ricciardo has been largely out of the public eye since being dropped by Red Bull almost 12 months ago.

Occasional social media posts have given a glimpse into his life of travel, while he spoke in July at a UK karting event that bears his name.

Similar comments on life in retirement followed on the Gold Coast this week.

“Well, I haven’t been shaving my face. The beard is my comfort right now,” the 36-year-old told Channel 7’s Mel McLaughlin.

“I had a fallout with my barber and then I lost my razor. It’s been a tough six months.”

Ricciardo said he has been “trying to figure out who I am”.

“I’ve lived this crazy, high-speed life for so long, and I just sat into a little bit of stillness. I suddenly wasn’t always surrounded by a tonne of people giving their opinions and thoughts,” he said.

“I’ve had a lot of time, I’ve done some hiking. I was in Alaska a few weeks ago and didn’t get mauled by a grizzly, which was a bonus.

“I’ve been trying to figure out who I am other than this race car driver.

“I’ve come to appreciate the little things more and the meaning of the importance of family and friends.

“I’ve always been driven, and that sometimes leads you to being selfish, so I’m trying to learn to be a bit more selfless and become a better listener.”

Wearing casual clothes and sipping a glass of whisky, Ricciardo addressed his F1 axing, saying: “This is it”.

“I never thought I would have this career. I never thought I’d be here, you know? That’s the truth,” he said.

“Yes, my dream was to be world champion, and there were years along the way where I genuinely felt like it was gonna happen.

“I got close, that’s OK. If I were a world champion sitting here today, would it change how I feel or how I view myself, or anything like that? I don’t think so.

“Maybe my ego would be big. We don’t want that. I have no regrets.”
