During the May 29-31, 2015 race weekend at Dover International Speedway, drivers will adorn their cars with the Autism Speaks blue puzzle piece. In total, 27 drivers from the NASCAR Sprint Cup Series, 16 drivers from the NASCAR XFINITY Series and 20 drivers from the NASCAR Camping World Truck Series will show their support for the cause.
This is the 9th consecutive year that the Monster Mile has partnered with Autism Speaks and the 5th year that FedEx has held the FedEx 400 benefitting Autism Speaks. Denny Hamlin will feature the puzzle piece more prominently on his No. 11 FedEx Cares Toyota.
