Walcott's Haulage had a truck going down a street perpendicular to Little Sutton Street on 25 June 2007. It passed by Donna Noble and Sylvia Noble in their car.
Soon afterwards, Donna from a parallel world travelled back in time, and jumped in front of the truck. The collision stopped traffic, allowing Donna's earlier self to turn left instead of right, setting the Time Beetle's manipulation right. (TV: Turn Left)
