According to the caption of the photo this is a multi-vehicle accident between four different pickup trucks on the race war. The race took place last Friday (Feb 18th 2005) at Daytona International Speedway. It looks like in the photo that the blue truck there completely lost it's tire as it is blowing sparks all over from it's driver side front wheel. The blue trucks hood is also crunched pretty good. In the larger photo there are two other truck, one of which has spun out into the grass at center of the track, and another where the hood looks like it is about to fly off. Both of the other trucks have smashed hoods as well.
