After the deaths of Ayrton Senna and Roland Ratzenberger at the San Marino Grand Prix , sweeping changes were announced by the FIA to the rules and regulations of Formula One in a bid to improve safety.

Both Williams and Simtek , the teams for whom Senna and Ratzenberger drove, ran only one car each during the race weekend.
