The 1994 San Marino Grand Prix  was a Formula One motor race held on 1 May 1994 at the Autodromo Enzo e Dino Ferrari, located in Imola, Italy. Michael Schumacher, driving for Benetton, won the race. Nicola Larini, with this Ferrari 412 T1, scored the first points of his career when he finished in second position. Mika Häkkinen finished third in a McLaren.

Austrian driver Roland Ratzenberger and three-time world champion Ayrton Senna were killed in separate accidents during the event. In addition to the two fatalities, other incidents saw injuries to driver Rubens Barrichello plus several mechanics and spectators. The deaths were the first fatalities in the Formula One World Championship since the 1982 Canadian Grand Prix, and the first with two driver deaths since the 1960 Belgian Grand Prix. Senna was given a state funeral in his home town of São Paulo, Brazil, where around 500,000 people (some numbers say 2 million) 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 verdict of not guilty.These tragedies 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. This led to a 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 incorporate large run-off areas to slow cars before they collide with a wall. As a result of increased standards in safety subsequent to this race, there were no fatalities for a period of 20 years from the deaths of Ratzenberger and Senna.

The Chronicle   The Race 

First start crash
Pedro Lamy leaving his wrecked Lotus 107C after hitting JJ Lehto's stalled Benetton B194, causing an early safety car.
No stoppage of the race was declared as a result of the accident between Lehto and Lamy,[ but the safety car driven by Max Angelelli was deployed, with all the remaining competitors holding position behind it while travelling at a reduced speed. During this period, as a result of travelling at slower speeds, tyre temperatures dropped. At the drivers' briefing before the race, Senna, along with Gerhard Berger, had expressed concern that the safety.

Restart, Senna crash and red flag
Once the track was reported clear of debris, the safety car was withdrawn and the race restarted at the conclusion of lap five
On the seventh lap, the second lap at racing speeds after the stoppage, Senna was leading Michael Schumacher. Going at a speed of 305 km/h (190 mph), Senna's car could not take the turn at the Tamburello left corner, and, continuing in a straight line, struck the unprotected concrete barrier at a speed of 211 km/h (131 mph), reduced as a result of the driver's effort to brake. As was subsequently ascertained, Senna was killed instantly.When track officials examined the wreckage of Senna's racing car, they found a furled Austrian flag. Senna had planned to raise it after the race, in honour of Ratzenberger
Second start
Michael Schumacher had a poor start because of wheelspin and Gerhard Berger took the lead on track — Schumacher still led the race overall due to the amount of time he was ahead of Berger before the race was stopped. Hill, from third, made contact attempting to overtake Schumacher at the Tosa corner, dropping Hill to the back of the field and was forced to make a pit stop in order to fit a new nose cone. Hill battled back to finish in sixth position.

Schumacher took the lead on track on lap 12 when Berger ran wide, before relinquishing the race lead overall to Berger when he made his first pit stop, confirming that his pace both before and after the red flag was down to his running a three-stop strategy, therefore racing with a lighter car. Berger made a pit stop at the end of lap 15 for his first of two scheduled stops, before retiring a lap later with handling problems. Häkkinen led his first ever laps of a Formula One World Championship race, before he made a pit stop at the conclusion of lap 18. Following the first series of pit stops, Schumacher resumed the race lead on aggregate, overtaking Nicola Larini on track at Tosa. Schumacher's extra pace as a result of his lighter fuel loads meant he was able to pull out enough of a gap to Häkkinen which enabled him to make an extra pit stop. Häkkinen's pace was very slow, allowing Larini to leapfrog him when drivers who planned to make two pit stops made their final pit stops.

Michael Schumacher won the race ahead of Larini and Häkkinen, giving him a maximum 30 points after 3 rounds of the 1994 Formula One season. It was the only podium finish of Larini's career, and the first of just two occasions when he scored world championship points
