#03 was recovering from getting caught on the grass but while trying to get back onto the the track #03 lost the rear end sending him into a spin, with #34 moving over trying to get out of the way he was to close to the spinning car infront off, with yellow flags warning #34 from danger infront off him he did not make enough space between him resulting with #34 going into the barrier.
Warning for both #03 (not taking care when rejoining the track) #34 (ignoring yellow flag and not taking care for danger infront of him).
