The 1994 Formula One season was already under scrutiny for dangerous conditions when, during the San Marino Grand Prix weekend at Imola, a series of accidents unfolded. Austrian rookie Roland Ratzenberger died during qualifying after a front-wing failure caused a crash at high speed. Brazilian three-time world champion Ayrton Senna then suffered a fatal crash early in the race itself.
On 1 May 1994, the third race of the 1994 Formula One World Championship was held at the Autodromo Enzo e Dino Ferrari in Imola. Michael Schumacher won the race, but the event was overshadowed by two driver deaths, injuries to Rubens Barrichello, and harm to several mechanics and spectators. Italian prosecutors later charged six individuals, including Frank Williams and Adrian Newey, with manslaughter in connection with Senna's death; all were eventually acquitted after a case lasting over 11 years.
The deaths of Senna and Ratzenberger prompted immediate and lasting safety reforms across Formula One. The Grand Prix Drivers' Association was revived after a 12-year hiatus, track layouts and car designs were overhauled, regulations were introduced to reduce car speeds, and new circuits required large run-off areas. These measures contributed to a 20-year period without an F1 driver fatality, ending only with Jules Bianchi's crash at the 2014 Japanese Grand Prix.
