The39th International 500-Mile Sweepstakes was held at theIndianapolis Motor Speedway on Monday, May 30, 1955. The event was race 1 of 11 of the1955 AAA National Championship Trail and was race 3 of 7 in the1955 World Championship of Drivers.

The race is notable to many as the race in whichBill Vukovich was killed in a crash while seemingly on his way to an unprecedented third consecutive Indy 500 win.

Time trials was scheduled for four days.

Gusty winds, as well as the threat of rain, was observed on pole day, therefore nearly all of the competitors stayed off the track. Around the garage area, the drivers and teams agreed amongst themselves to sit out time trials for the afternoon, and instead qualify together in better conditions on Sunday. However, in the final 20 minutes,Jerry Hoyt, who had not been informed about the agreement, suddenly put his car in line, and pulled away for an unexpected qualifying attempt. His speed of 140.045 mph was not spectacular, but as the fastest (and only) car thus far of the day, he sat on the pole position. Without hesitation,Tony Bettenhausen Sr. took to the track moments later. After two fast laps, he was slowed by a gust of wind, and qualified second.Sam Hanks andPat O'Connor got their cars ready, but neither were able to complete attempts. The day closed with only two cars in the field, and Hoyt the surprising pole winner – to the dismay of several in the garage area.

Qualifying resumed in better conditions, and most of the drivers who stayed off the track Saturday took to the track on Sunday.Jack McGrath (142.580 mph) was the fastest qualifier, and lined up third. Hoyt's pole-winning speed from the day before ended up being only the 8th-fastest overall in the field – a record slowest ranked pole speed.

Near the end of the day,Manny Ayulo crashed due to a possible steering fault and died the following day.

Paul Russo, attempting to qualify the #18 Novi for Troy Ruttman, suffers a broken gearbox. This was the last appearance of a front-drive car at Indy.

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 amagneto 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.^[5]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 contactingJohnny 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.^[6] DriverEd 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 byBob Sweikert. The only other driver to retire due to contact for the remainder of the race wasCal Niday on lap 170.^[7]Art Cross led the race from laps 133 to 156, but after surrendering the lead toDon 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.^[8]

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 atMonza, and ahorrific accident at the24 Hours of Le Mans which saw nearly 100 fatalities includingPierre Levegh who was driving at the time of the accident. Following the year theAmerican Automobile Association ceased sanctioning auto races (including the Indy 500) and theUnited States Auto Club (USAC) was formed to handle sanctioning duties.^[9] It would take until 1959 for fire suits to be made mandatory for all drivers androll bars for all cars afterJerry Unser's fatal accident at the1959 Indianapolis 500.^[10]

The Indianapolis 500 was included in theFIAWorld Championship of Drivers from1950 through1960. The race was sanctioned byAAA through1955, and then byUSAC beginning in1956. At the time the new world championship was announced and first organized by theCSI, the United States did not yet have aGrand Prix. Indianapolis Motor Speedway vice president and general manager Theodore E. "Pop" Meyers lobbied that the Indianapolis 500 be selected as the race to represent the country and to pay points towards the world championship.^[17][18]

Drivers competing at the Indianapolis 500 in 1950 through 1960 were credited with participation in and earned points towards the World Championship of Drivers.^[19] However, the machines competing at Indianapolis were not necessarily run toFormula One specifications and regulations.^[20] The drivers also earned separate points (on a differentscale) towards the respectiveAAA orUSACnational championships. No points, however, were awarded by the FIA towards theWorld Constructors' Championship.

The 1955 Indianapolis 500 was round 3 of 7 on the1955 World Championship. The event, however, failed to attract interest from any of the regular competitors on the Grand Prix circuit. Race winnerBob Sweikert earned 8 points towards the World Championship. Despite not competing in any of the other World Championship events, he finished seventh in the final season standings.
