Driving extremely erratically, randomly speeding up and slowing down, swerving off the road then suddenly swerving back on and almost hitting other cars. Possibly under the influence of something.
This guy has a set of Lights on his front dash. He turned them on while in traffic trying to get people to move out of his way. Saw him pull into work at an Auto zone parts store.
Great last minute reaction! Moved quick to avoid pile up and saved many from the same!
