If an accident blocks the track, the race is stopped by red flags shown at every marshalling post. If this occurs more than two laps into the race but before 75 per cent of the allocated distance has been completed, the race is restarted 20 minutes later, with the grid formed by the race order on the lap prior to the red flag. The cars must line up on the grid and cannot make for the pits. No fuel can be added to the cars on the grid. Because the results in this instance are an aggregate of the elapsed times of each competitor from the two parts of the race, it�s quite conceivable that strategies will be unaffected. Any advantage carried by one driver over a rival is still maintained in the aggregate result, even if not on track. But consider, say, the McLaren driver who was leading the Williams rival until pitting just before the stoppage. The slower Jordan and Sauber cars directly ahead of him � which might previously have been out of his way � are now holding him up because the restart has bunched them all together. The Williams rival who has not yet pitted is on a clear track and is brought in earlier than planned in order to take advantage of the McLaren�s delay and get out still ahead. Lots of celebration at Williams, glum faces at McLaren. Stoppages that occur after 75 per cent distance can throw the race wide open for different reasons. In this situation, the race is considered over, and the race order on the lap preceding the stoppage becomes the result. This would be very bad news for any driver who had pitted just prior to the stoppage. Who said life was fair?
