She was spotted behind the wheel of her Range Rover as she drove out of the Sandringham estate.
The Queen was wearing a headscarf and bright red lipstick and was accompanied by a companion and followed behind by her police protection officers.
It comes after she was seen driving along a public road, less than 24 hours after Prince Philip's accident, without wearing a seatbelt as she headed home after visiting her stables.
The Duke was not injured in the crash, which also involved a Kia car, but doctors are closely monitoring him. Two women in the Kia were taken to hospital and treated for minor injuries and then discharged.
