In a story that has made national headlines, a Dallas Area Rapid Transit (DART) van crashed into a line of stopped vehicles on the Dallas North Tollway on June 29, 2012. North Texas Transit Authority officials recently released the video publicly. It’s clear the van’s driver didn’t stop until he slammed into the cars, injuring several peoples. The van normally transports disabled passengers, but fortunately it had no one else aboard besides the driver. The driver of the first vehicle struck remains hospitalized in critical condition. It’s unclear why the van driver didn’t stop. But, it’s also frightening in that thousands of people take the Tollway every day. I used to take it almost daily when I worked in downtown Dallas. Officials are still investigating.
