The royal family’s security team ensures that, in certain situations, senior members are not required to wear a seatbelt.

Over the years, we’ve come to learn about the many unusual rules royals must follow—from always packing a black outfit when traveling to the strict ban on two heirs flying together on the same flight.

But it doesn’t stop there. Even the words they’re allowed to use are regulated, and senior members often have extra rules to abide by. For example, Kate Middleton reportedly has five more protocols to follow than her sister-in-law, Meghan Markle.

That said, not wearing a seatbelt while traveling in a car is illegal in the UK. So why is it that we almost never see the royals buckled up?

The decision was made with their safety in mind by members of their security team, who prioritize ensuring royals can be quickly extracted from a vehicle in an emergency.

Speaking to the Daily Mail, British security expert Michael Chandler explained: “The main reason royals might not wear seatbelts is because of security considerations. As you might imagine, there’s concerns about extracting a principal from a vehicle as quickly as possible.”
