2003 Daytona 500

2000 NASCAR Busch Series champion Jeff Green won his second career Winston Cup pole.

Prior to the race, the drivers paid tribute by having decals on their cars in honor of the astronauts who were killed in the Space Shuttle Columbia disaster two weeks earlier, similar to the 1986 Daytona 500, in which they paid tribute to the fallen crew members of the Space Shuttle Challenger disaster.

In addition, the pledge of allegiance and pre-race opening invocation given by the Reverend Hal Marchman, in his next-to-last running of the event before his retirement and subsequent death, were recited.

This is the first Daytona 500 event that respected Winston Cup veteran Dave Marcis did not attempt since 1967, a whole season before he had started driving.

The green flag came nearly half an hour earlier than planned, due to the impending rain showers which officials feared would lead to the race having to be completed on another day.

Jeff Green was out in front at the start of the race, but he was quickly passed by Michael Waltrip who led the first 34 laps.
