Las Vegas Motor Speedway
On October 16, 2011, the final race of the 2011 IndyCar season, the IZOD IndyCar World Championship, was held at Las Vegas. However, the race was halted by a horrific crash on lap 11 that involved 15 cars, some of which became airborne, and some of which burst into flames. The crash began when Wade Cunningham made light contact with James Hinchcliffe, but the situation turned into a big pile-up of cars. The crash allowed a red flag to be waved almost instantly, due to the remains of the damaged cars and the amount of debris on the track.
IZOD IndyCar World Championships
In 2004–2005, the Champ Car series held a race at Las Vegas Motor Speedway. Both editions were held under the lights on a Saturday night as part of the NASCAR Craftsman Truck Series weekend in the fall. After only two years, however, the race was considered unpopular and was removed from the schedule.
