A trucker’s dash cam was rolling to capture a stunning high speed crash that certainly looked fatal — until the moment that the motorist got out of his mangled vehicle and walked away.

The dash cam clip was shared by Facebook user Tony Stewart on September 10.

In the clip, a semi truck driver appears to be waiting at a traffic light when a white BMW skids past the dash cammer’s truck at a very high rate of speed and buries itself under the waiting truck’s trailer.

Stewart said, “What an idiot……wait for it! BTW the driver of the BMW walked away from this crash…watch till end you’ll see him exit car from the right.”

Stewart also shared a remarkable photo of the crashed BMW.
