Buckingham Palace said Philip received a "precautionary checkup" at Queen Elizabeth Hospital in King's Lynn on Friday and was found to have "no injuries of concern".
"Eyewitnesses told BBC News that the Range Rover the Duke was driving was overturned in the crash and that he was "'very, very shocked' and shaken" after being helped out of the auto.
The other driver involved in the collision "suffered cuts while the female passenger sustained an arm injury, both requiring hospital treatment", police said in a statement.
The Palace has confirmed he still indeed does hold a valid driving licence, telling Express.co.uk "Prince Philip followed all the usual DVLA practices". The monarch, who is a big supporter of eco-friendly living, is often seen driving his Volvo XC60 T8 which runs both on petrol and electricity.
Warne said: "The roof was where the window should have been because it was on its side. Local police attended the scene", the Palace added in a statement.
"I saw it careering, tumbling across the road and ending up on the other side". "I saw a black, four-by-four type vehicle on its side and me and my son were like "oh my word, that doesn't look good". He then pulled him out of the Land Rover through the windscreen or sun roof.
One of the women who is aged 45-year-old broke her wrist during the incident.
Or are we barking up the wrong tree because in fact, the royals probably get helicopters for any arduous journey and, really, Prince Philip was on his way to the Sainsbury's in King's Lynn to get some snacks? When that person is the Duke of Edinburgh, the debate is a national one.
"One of the royal entourage gave me a wipe to wipe my hands", he said, adding that "a lot" of Prince Phillip's aides arrived at the scene in another vehicle very quickly.
The duke, who retired from public duties in 2017 but remains active, could also avoid prosecution by surrendering his licence, according to the lawyer known for representing celebrity clients like David Beckham.
Reportedly, the accident occurred as Prince Philip drove a Range Rover out of the driveway at about 3 p.m. Greenwich Mean Time in Great Britain - or 10 a.m. EST - near the village of Babingley.
While there is no age limit for driving in the United Kingdom, motorists must renew their licence at least 90 days before reaching the age of 70, and then every three years after that.
"If driving restrictions based on age and safety were introduced, we would be more likely to restrict young drivers rather than older drivers", he said.
