Bad Move Over

O’Bar describes the crash:

A Pot-O-Gold Sewage tank driver made a quick maneuver to pull over behind a Dallas County Sheriff on the shoulder near the junction of I-20E and I-635N in Balch Springs, TX. The driver of the Cheeseman trailer did not anticipate his quick stop and dove into the adjacent lane, cutting off a bulk tanker. The bulk tanker could not stop quick enough.
