This is a very dangerous stretch of road which is often complicated by heavy tractor trailer usage. Drivers need to be aware that tractor trailers are massive and ten times the weight or more of their own vehicle. I observe unsafe and poor driving etiquette towards tractor trailers on a daily basis. If drivers dart around a tractor trailer at speed and the tractor trailer driver has a hard time seeing a vehicle within his mirrors this causes accidents. Perhaps checking to make sure that there is an actual human being inside the cab of the truck as drivers try and speed around this 18 wheeled 50,000 pound obstacle would help. I drive as aggressively as others on the highway, but when approaching a tractor trailer I make sure I can see the driver in his mirrors, and rather than dart around him and potentially cut him off, I try to observe his path and make sure its clear for not only myself, but also for everyone around me. You'd be surprised at how rare that is and how much respect is shown by tractor trailer drivers for not cutting them off. Simply communicating with a wave to their drivers side mirror as you get ready to pass or a headlight flash that lets them know that they can get over if they need to can go very far in adding safety to our roads.
I saw this accident scene as I traveled south that afternoon. The debris littered the road for half a mile. A Chrysler minivan looked as if it had been put into a car crusher. A Volvo sedan was also crushed badly. An emergency helicopter was used to transport one or more of the accident victims to nearby emergency facilities. Traffic was stopped for several miles.
I snapped a photo with my iPhone as I drove by at a crawl. I also immediately warned my social network fans, friends, family via facebook with a quick post concerning the location.
I am not a tractor trailer driver, but I have known a few in my lifetime, and their stories of how stupid decisions are made by drivers of smaller vehicles have scared me into respecting this larger, but fellow traveler on the highways.
