Jack McGrath, starting from the outside despite the fastest qualifying time, grabbed the initial lead, but was quickly challenged by Bill Vukovich, who was looking for his third consecutive win. Vukovich took the lead on lap four, surrendering it back to McGrath on lap 15 but regaining it on lap 16. Fred Agabashian, who had finished in the top ten the previous two years spun on lap 39 and could not continue. McGrath chased Vukovich until lap 54, when he pulled over with mechanical problems. Despite getting out of the car and attempting to repair it himself, he was forced to drop out with a magneto issue. With Vukovich having a considerable lead on lap 56, Rodger Ward, several laps down, flipped over twice, either due to a problem with the wind, oil, or breaking an axle. Although he landed on his wheels, the car was facing the wrong way.[4] Al Keller, attempting to avoid Ward, turned to the inside, going close to or on to the grass, before turning hard to the right and coming quickly back up the track and contacting Johnny Boyd. Boyd's car careened into Vukovich, who appeared to be attempting to also go to the left of Ward. Vukovich made a last second attempt to avoid Boyd to the right, but Boyd's car sent Vukovich hard into the outside barrier. Vukovich's front end also lifted into the air, causing the front to clear the barrier and the car to contact it with the rear, sending the car into a cartwheel, during which it hit several vehicles parked outside the track, and possibly a pole. The car burst into flames after it came to rest, and Vukovich died from injuries from the crash. Boyd's car also flipped but he and the other drivers escaped major injury.[5] Driver Ed Elisian stopped his car on the infield and ran across the track in an attempt to help Vukovich.

After 27 minutes of running under caution, Jimmy Bryan took over the lead of the race, but was forced to retire after ninety laps with a fuel pump issue, when the lead was taken over by Bob Sweikert. The only other driver to retire due to contact for the remainder of the race was Cal Niday on lap 170.[6] Art Cross led the race from laps 133 to 156, but after surrendering the lead to Don Freeland was forced to retire due to mechanical trouble on lap 168. Freeland similarly was passed by Sweikert on lap 160, and retired on lap 178. Sweikert led the remainder of the race. Sweikert stated that the winds made racing difficult, and perhaps led to a decision of racing cautiously and taking advantage of other's difficulty.[7]

The two deaths in the 500 were part of a particularly deadly year for motorsports, which also included four other Indy drivers dying in other races, Alberto Ascari being killed while testing a sports car at Monza, and a horrific accident at the 24 Hours of Le Mans which saw nearly 100 fatalities including Pierre Levegh who was driving at the time of the accident. Following the year the American Automobile Association ceased sanctioning auto races (including the Indy 500) and the United States Auto Club (USAC) was formed to handle sanctioning duties.[8] It would take until 1959 for fire suits to be made mandatory for all drivers and roll bars for all cars after Jerry Unser's fatal accident at the 1959 Indianapolis 500.[9]

Notes

• ^1 – Points towards the 1955 World Drivers' Championship
• ^2 – 1 point for fastest lead lap

• Pole position: Jerry Hoyt – 1:04.27 (while Hoyt started on the pole, Jack McGrath set the fastest time but started on the outside of the first row)
• Fastest Lead Lap: Bill Vukovich – 1:03.67
• Shared Drives:
  • Car #10: Tony Bettenhausen (123 laps) and Paul Russo (77 laps). They shared the 6 points for second place.
  • Car #77: Walt Faulkner (176 laps) and Bill Homeier (24 laps). They shared the 2 points for fifth place.
• While in the lead, Bill Vukovich hit the 3-car pileup of Al Keller, Johnny Boyd, and Rodger Ward. He was killed (by fracture to the skull) when his car became airborne and went out of the course on the back long straightaway, landing upside down and on fire. His death concluded a streak of three straight years leading the most laps in the race (likely to have been four straight, 1955 inclusive), a feat unequaled since.
• Formula 1 championship debut for Keith Andrews, Johnny Boyd, Ray Crawford, Al Herman, Al Keller, Eddie Russo, Shorty Templeman and Chuck Weyant
