1994 San Marino Grand Prix

The 1994 San Marino Grand Prix (formally the 14° Gran Premio di San Marino) was a Formula One motor race held on 1 May 1994 at the Autodromo Enzo e Dino Ferrari, Imola, Italy. It was the third race of the 1994 Formula One season. Events at this race proved to be a major turning point in both the 1994 season, and in the development of Formula One itself, particularly with regard to safety.

The race weekend was marred by the deaths of Austrian driver Roland Ratzenberger and of three-time world champion Ayrton Senna in separate accidents. Other incidents saw driver Rubens Barrichello injured and several mechanics and spectators injured. BBC Television commentator Murray Walker described it as "the blackest day for Grand Prix racing that I can remember".

Michael Schumacher won the restarted race. In the press conference following the race, Schumacher said that he "couldn't feel satisfied, couldn't feel happy" with his win following the events that had occurred during the race weekend. Nicola Larini scored the first points of his career when he achieved a podium finish in second position. Mika Häkkinen finished third.

The race led to an increased emphasis on safety in the sport as well as the reforming of the Grand Prix Drivers' Association after a 12-year hiatus, and the changing of many track layouts and car designs. Since the race, numerous regulation changes have been made to slow Formula One cars down and new circuits, such as Bahrain International Circuit, incorporate large run-off areas to slow cars before they collide with a wall. Senna was given a state funeral in his home country of Brazil, where around 500,000 people lined the streets to watch the coffin pass. Italian prosecutors charged six people with manslaughter in connection with Senna's death, all of whom were later acquitted. The case took more than 11 years to conclude due to an appeal and a retrial following the original not guilty verdict.
