Charlotte Motor Speedway has scheduled 35 hours of open testing for NASCAR Craftsman Truck, Busch and NEXTEL Cup Series teams in preparation for the track's slate of May races, including the May 21 NASCAR NEXTEL All-Star Challenge and the May 29 Coca-Cola 600.

The testing schedule:
April 26, NASCAR Craftsman Truck Series, 3 p.m. to 10 p.m.
May 3-4, NASCAR NEXTEL Cup Series, 3 p.m. to 10 p.m.
