Two days after Prince Philip was involved in a car crash that injured two women and prompted a debate on older drivers in Britain, the police gave him a warning after he was photographed driving on Saturday in another vehicle — this time apparently without a seatbelt.

British news outlets published a photo of the 97-year-old duke behind the wheel of a Land Rover outside the Sandringham Estate, a private property of the royal family in Norfolk County in eastern England.

The police said officers had approached the driver.

“Suitable words of advice have been given to the driver,” a spokeswoman for the Norfolk Police said in a statement on Sunday. She added that it was standard policy when “being made aware of or receiving such images showing this type of offense.”

News of the genteel warning to the husband of Queen Elizabeth II came as a woman who broke her wrist in the crash, Emma Fairweather, 46, complained in an interview with the British tabloid The Mirror that the prince has yet to offer her an apology.
