The Norfolk police are going to investigate the Duke of Edinburgh's car accident, leaving two people in need of hospital treatment, saying that appropriate action will be taken.
Prince Philip, 97, was returning to the Sandringham property on Friday, as further details emerged from the accident on Thursday which left him "very shaken and shocked" but otherwise rude.
A witness, Roy Warne, 75, who drove home, described the prince's Land Rover Freelander toppling over the road after the collision as he pulled out of a driveway near the Queen's Norfolk property to the A1
The car turned on its side after colliding with a Kia containing two female passengers and a nine-month-old baby. The women both suffered minor injuries and required hospital treatment, but were later discharged, police said.
Both drivers were breathing and gave negative readings.
The Norfolk police confirmed the nine-month-old baby boy in Kia uninjured.
A spokesman said: "Kia, a 28-year-old woman, led to the cutting of the knee while the passenger, a 45-year-old woman, maintained a broken wrist. Both deaths were treated at the Queen Elizabeth hospital in King's Bay. Lynn and was discharged last night.
"As is the standard procedure of damage collisions, the incident will be investigated and any appropriate precautions taken. We are aware of the public interest in this case, but as with any other investigation, it would be inappropriate to speculate on the causes of the collision until an investigation is completed. "
Warne told BBC Radio's Today program that he and another man helped rid the baby of the first vehicle. Warne helped get the prince out of his ruined Land Rover either through the sunroof or the broken windshield.
"I drove home and I saw a car, a black Range Rover, came out of a side road and rolled and ended on the other side of the road, and there was a huge collision with another car, "He said.
" I went to the other car. There was a baby in the back and with another man we got the baby out. Then I went to the black car to help and realized it was the Duke of Edinburgh. "
He said the prince was caught with his legs in the car's well." I asked him to move his left leg and it freed his right leg and then I helped him get out. "
Warne said: "The roof was where the window should have been because it was on its side. I think I helped him out through either the sunshade or the front windshield, but I'm a little blurred. "
Asked what the prince had said during the rescue, Warne replied:" I can't remember but it was nothing rude. He was apparently shaken, and then he went and asked if everyone else was okay. "
Prince Philip was able to stand and walk, but there was" a little blood, "Warne said, suggesting that the prince had been cut off broken glass." There was a little blood, and one of The royal followers gave me a drought to dry my hands, "he said.
Warne said about the crash:" I think it is undoubtedly hit [by the prince’s car]. It's my memory. "
By Prince Philips vehicle, he said," I didn't see it from the side street. I saw it career and tumbled across the road and ended up on the other side. It would take a massive force and it had rolled on the other side as well. "
The Prince was taken to Sandringham, where he was seen by a doctor as a" security measure, "Buckingham Palace said on Thursday.  Previously, concerns about road safety on A149 near Sandringham, on Friday, Norfolk County Council, Randomly planned to discuss security measures at A149 where the collision occurred, speed limit approved plans lowered from 60mph to 50mph and to implement an average speed monitoring system.
Older drivers must renew their driving license every three years after they are 70, but is not required to resume a driving test and there are no laws as to which age to stop driving.
Buckingham Palace said: "The Duke of Edinburgh has a valid driving license and completes all the usual DVLA processes. "
If the prince is considered responsible, he may be accused of driving without care and attention. The lawyer Nick Freeman, known as Mr. Loophole, who has represented celebrities prosecuted over alleged traffic offenses, said he believed that The prince could have a good defense if he blamed being blinded by the sun as a witness claimed. He could also avoid prosecution by surrendering his license, Freeman told the Press Association.
"If the sun was so low and right your eyes, it is sometimes impossible to see, and it might well have been the case, give him a defense, "Freeman said.
The Crown Crime Service would consider whether it was in the public interest to prosecute if the king was found guilty . "I think that even though he has found errors, I think someone advises him, would contact CPS and say, see, he now accepts that he should not drive and he will commit to over Give his license and not run again, said Freeman.
But the decision was to be balanced with the wishes of the other cars that both required hospital treatment, he added. "They can say," We don't care who he is. "They could think of his age, in his position he could afford a driver. He has all the facilities he should not risk the lives of others. They can push for a prosecution."
