Something was not quite right, the trucker drifted downhill 45 minutes after hitting another trucker... and though he just hit a tree, said he was "all right" laying across the seat. Must be a medical problem, maybe diabetic shock?

According to this Facebook post, the driver of the tanker truck ran into another semi at a rest stop in Cottondale, Alabama on Feb. 28th.

The driver who was hit by the tanker captured the above video, 45 minutes after he was hit, while waiting for police to arrive. The recording driver, Bobby Bink Carr, said the crash may have been caused due to a medical condition.
