The Princess of Wales brought the traffic to a halt, quite literally, as she continued a day of engagements in the Principality.
As she headed away from a visit to the Corgi factory in Ammanford, Catherine spotted some wellwishers who had turned out to see her as she continued her previously unannounced trip.
The Princess asked for her car to stop and she got out and made her way across to the group waiting at the roadside.
She was offered a toy banana by one young fan who asked her if she was a princess.
The unexpected stop came after Catherine had toured the factory which makes socks and jumpers.
She had tried her hand at adding the toe to a sock but had taken several attempts and joked that she was struggling to get the hang of it.
Earlier, the Princess visited the Ty Hafan Children’s Hospice to meet parents and young people supported there as well as the staff and volunteers who look after them.
Just before her arrival, it was announced that the Princess of Wales has become the patron of the hospice, taking over from King Charles.
The patronage was previously held by Diana, Princess of Wales.
During her time at Ty Hafan, Catherine played with some of the young people being looked after there and also made a hand print, which she signed, as a permanent reminder of her visit.
