Why runaway truck ramps are useful


This rather jerky video (obviously recorded at only one or two frames per second) shows a runaway truck on a California mountain road in April this year.  The truck uses a runaway ramp to stop itself, almost turning over in the process.  It's a very graphic illustration of why they build them - the thought of that much mass running amok at high speed through lighter vehicles further down the road is chilling.  Watch in full-screen mode for best results.
