The incident occurred on Thursday, June 30, when Mary, 52, and her husband, King Frederik, 56, were on a week-long tour of Greenland.
A video obtained by the Danish publication Ekstra Bladet shows the moment when Mary was nearly knocked to the ground by an elderly man on a scooter as she greeted crowds in Nuuk. Onlookers gasped audibly as Mary cried out, though she quickly regained her composure while her security team leapt into action.
A palace spokesperson later confirmed to Ekstra Bladet that no one was injured in the collision. Mary and Frederik continued with their schedule, traveling to Igaliku and Qassiarsuk on the island in the North Atlantic Ocean, which is part of the Realm of Denmark.
The couple was joined by their youngest children, 13-year-old twins Prince Vincent and Princess Josephine, for part of their trip, during which they sailed on the Royal Ship Dannebrog.
Frederik and Mary are now on their summer break at Gråsten Palace, as is traditional for the Danish royals.
It was also confirmed earlier this week that the couple, who celebrated their 20th wedding anniversary in May, are taking a private trip abroad. Their eldest son, Crown Prince Christian, 18, is acting as regent while his parents are out of the country.
