right. Ralf Schumacher slid before turn one and he defended his position at the corner. That caused the left-front corner of Barrichello's Ferrari and the rear of Ralf Schumacher's Williams car to connect; Schumacher spun 180 degrees in front of the pack, sending him to the rear of the field. In doing so, Irvine was sent into a half-spin by Verstappen as Räikkönen drove near the pit lane wall with a broken transmission. Elsewhere, Häkkinen slowed to avoid piling into Ralf Schumacher. He fell from fourth to eighth as his teammate Coulthard moved from eighth to fourth after going into the grass to avoid the incidents. Verstappen moved from 18th to sixth by the end of the first lap by driving on the inside, as Ralf Schumacher fell from third to 20th over the same distance. At the end of the first lap, Michael Schumacher led his teammate Barrichello in second by 1.3 seconds, with Trulli a further 1.8 seconds behind in third. As the two Ferraris pulled away from the rest of the field on lap two, Panis' engine failed, pitching his car backwards into the gravel trap. Leaking oil pooled on the track and dripped onto his hot exhaust, where it ignited. Fisichella overtook his teammate Button for 11th as Ralf Schumacher moved from 20th to 14th. An unexpected monsoon shower began to fall on lap three. The two Ferraris continued to pull further away from the rest of the field, although they were unaware of Panis' deposited oil. Both drivers slid on the oil and into the gravel trap, and navigated back onto the track in third and seventh. Trulli took the lead with Coulthard in second. None of the leaders made pit stops to switch to wet-weather compound tyres immediately because half of the track was dry while the final hairpin was flooded. On lap four, Montoya, Bernoldi, Heidfeld and Villeneuve aquaplaned into a gravel trap and retired. Race officials deployed the safety car on the lap though several cars, including Trulli, Coulthard and Barrichello, aquaplaned into the turn 15 hairpin. During the safety car period, several drivers made pit stops for rain tyres. Although he had no radio communication with his team, Coulthard exited the pit lane leading while Ferrari had a fraught stop. After Ferrari technical director Ross Brawn called both Michael Schumacher and his teammate Barrichello for their first pit stops, Schumacher sat
