The alternative to a standing start is a rolling start. Standing starts are often deemed safer in Formula sports, due to the higher acceleration speeds, which could cause problems if a rolling start were used, based on the speed of the safety car and regulations regarding the start (some forms of motorsport are strict on when cars may accelerate after the safety car enters pit lane—some do not permit acceleration until the cars are near the start line at starter's orders). A standing start can cause problems, however, such as stalled cars being hit by drivers who start behind them on the grid. Riccardo Paletti was killed in just such an accident at the 1982 Canadian Grand Prix. Another example was the 2007 Champ Car Mont-Tremblant, where multiple cars stalled on the start, resulting in a safety car. Motorsports using standing starts usually penalize drivers who "jump the start" by moving before the lights are extinguished.
