A fan at the Tour de France caused an enormous pile-up when cyclist Tony Martin crashed into the fan's cardboard sign during Stage 1 on Saturday.
The fan was not looking at the incoming peloton while facing the camera and holding a sign that extended over the road. After the initial impact, Martin's team fell around the cyclist causing much of the pack to pile up around the collision.
Chaos erupted in the aftermath of the crash as riders waited for new bikes while others at the back of the pack waited for the road to clear.
