Cyclists competing in the Tour Down Under this week might have been left a touch confused when a truck drove off with the finish line.

The archway over the finish line of stage one in the women's event in Adelaide got caught at a truck drove underneath it.

The action, caught during an ABC News broadcast, show the truck may have been a little bit too tall for the arch and instead of carrying on without an issue, it lifted the finish line and took it with it.
