The Pittsburgh Left involves two cars facing one another waiting at a traffic light or other stop signal: one turning left and one going straight. The left-turning car will execute its turn through the intersection before the car going straight passes through the intersection, where normally it would yield. Permission to do so is either given by the car going straight, or sometimes taken by the left-turning car by starting through the left turn early enough so as not to obstruct the straight-going driver. This practice is seen as courteous, because a very small delay for the oncoming vehicle can eliminate a long delay for the left turning vehicle and those blocked behind it.
