On lap 4 Patrese retired due to suspension failure. Whilst Prost extended his lead, Senna was under pressure from Hill who overtook him for second place on lap 11. On lap 25 Senna was given a stop-go penalty after overtaking a backmarker under yellow flags, which meant he re-entered the race behind Schumacher. Heavy rain then caused many drivers to spin with Fittipaldi and Prost retiring. Fittipaldi spun on lap 30 and as he was returning to the track Prost crashed into him. After the accident the safety car was brought out with Hill leading the race.
