Walmart driver Ronald Emenheiser was named the 2015 Bendix Grand Champion at the 78th annual National Truck Driving Championships and National Step Van Driving Championships in St. Louis.

This year was his second trip to the National Truck Driving Championships. Hosted by American Trucking Associations, the event featured 431 competitors representing 85 different companies.

The skills course tested drivers' ability to judge distances, maneuver tight spaces, reverse, and position their vehicle exactly over scales, before barriers or around curves.
