According to BT.com, Yoriko Hirose, 38, a research assistant from St Andrews, caught the moment on camera, and said: "I was on my way to work and saw a police car speeding next to me.
"Then I saw the officer get out and noticed the traffic was being held up by ducks in the middle of the road."
The Metroreports he added: "I just started filming. It was a dramatic moment. It was interesting and a bit surreal.
"The police did a good job. They managed to get the ducks off the road quite quickly."
