The Queen was reported to police for not wearing a seatbelt as she travelled to the State Opening of Parliament in her official call.
West Yorkshire Police said they received a 999 call about the royal journey.
But the force said the caller also thought it was a good idea to ring their local police force, as the Queen was travelled with Prince Charles through London from Buckingham Palace to Westminster.
Confirming the call in a tweet, it also pointed out that the call was not an emergency and should not have been made to 999.
“999 call received reporting that the Queen isn’t wearing a seatbelt. #not999 #notevenwestyorkshire,” the tweet read.
Under UK law, civil and criminal proceedings cannot be taken against the Queen.
Her press office said it would not comment on the tweet.
