As the Queen traveled to Westminster this week for the State Opening of Parliament, one eagle-eyed observer noticed she wasn’t wearing her seat belt as she rode in the rear of the car.

This observer then decided that such a flagrant, public flouting road safety regulations ought not go unpunished – and so dialed 999.

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.

But under the Queen and law section of the Royal Family’s website, it states: “The Queen is careful to ensure that all her activities in her personal capacities are carried out in strict accordance with the law.”

It is unclear what the caller was trying to achieve by ringing the police.

The London Metropolitan Police recently released a list of 10 of the most ridiculous time-wasting calls it had received of late:

• A woman who had seen a clown in London selling balloons for £5 each, which was “much more than other clowns were charging”
• A woman who said she had bought a cold kebab and the shop would not give her a replacement
• A man who called 999 as he was advised to phone 111, but did not know the number
• A caller who dialled 999 at 4am on a Saturday and asked: “Where is the best place to get a bacon sandwich right now?”
• A man who said his 50p coin was stuck in a washing machine at his local launderette and wanted police to retrieve it
• Callers who missed their alarm and were going to be late for a flight and wanted officers to take them to the airport
• Callers in distress because their low fuel indicator light had come on
• A man who did not have change for a parking machine and who claimed staff at a car park had kidnapped him because they were refusing to let him out for free
• A woman who wanted police to deal with a pair of noisy foxes outside her home as they were preventing her from sleeping
• A woman who said there were men in her house trying to take her away. The men in question were actually police officers who had come to arrest her
