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.

For the first four runnings, the race was advertised as a 500 km race. Starting in 1997, the race was moved to a night race. In 2000, it was moved from the fall to the spring, and returned to a day race. After 2000, the race was removed from the IndyCar Series for a decade.
