Hwy 78 running between Stone Mountain to the center of Snellville has a reversible lane system. From 1am-11am it has 3WB lanes a turn lane and 2EB lanes. 11am-1am it has 3EB 1 turn and 2WB. The system has been around as long as I can remember (at least 87) however allot of accidents are caused by people like these who can't figure out the big green arrows, white curved arrows, and big red X's over each lane. So many accidents in fact they are in the process of figuring out a way to do away with the reversible lanes.

This lady can't figure out which lane is the turn lane so she sits in both of them…
