"Jackass" star Ryan Dunn's Porsche careened off the highway and THROUGH a metal guardrail ... leaving behind a long trail of tire marks ... and the video tells the gruesome story.
As we previously reported, police found Dunn's car "off the road and in the woods" this morning in Pennsylvania -- completely engulfed in flames.
Thanks to Daily Local News for the clip.
