Rain and the threat of tornados wasn't enough to keep truckers away from the Shell Rotella SuperRigs Contest in Concord, N.C. May 15 to 17.

The annual contest came to the Z-Max Dragway, adjacent to the famous Charlotte Motor Speedway, home of NASCAR. The competition saw big rigs from all over the country competing in a truck beauty contest, facing down the scrutinizing glare of exacting judges. ENR was there, and has compiled a slide show of some of the sights at the competition.
