# List of fatalities at the Indianapolis Motor Speedway

The following is a list of 74 individuals whose deaths have been related to the Indianapolis Motor Speedway, located in Speedway, Indiana: 42 drivers, 1 motorcyclist, 13 riding mechanics, and 18 others including a pit crew member, track personnel, and spectators have sustained fatal injuries or have had fatal medical conditions. The fatalities are connected with Championship Car racing at the track unless otherwise noted.
59 of the 74 fatalities have occurred as part of the Indianapolis 500 (including the race, qualifying, and practice). Fatalities have also occurred in conjunction with the precursors to the 500 (which took place in 1909 and 1910), the Brickyard 400, the Moto GP event, the Speedway's golf course, and during private testing.
During World War I, while the Speedway was being used as a landing strip and a maintenance and refueling station for the 821st Aero Repair Squadron, at least one test pilot was fatally injured in a plane crash at the track. In July of 1926, the Speedway neighborhood of Indianapolis voted to incorporate itself as an independent town, Speedway, Indiana.

| Albert Opalko | Riding mechanic | May 28, 1937 | AAA | Indianapolis 500 | Qualifying | Having completed four of ten scheduled qualifying laps, Frank McGurk's car plunged through an inner rail, overturned and ejected both McGurk, who was hospitalized in serious condition but survived, and his riding mechanic Albert Opalko, who was killed. The crash was caused by a broken connecting rod. Opalko is the most recent driver to be fatally injured during an official qualifying run — all subsequent fatalities during time trials have occurred on warm-up laps, prior to receiving the green flag to officially start the respective runs. |
| Everett Spence | Spectator | May 30, 1938 | AAA | Indianapolis 500 | Race | When the tire and rim came off a wheel of the Elgin Piston Special driven by Emil Andres, the car was sent spinning, rolled over three times, ejecting the driver, and only came to a stop after penetrating the inner rail. Andres, who had sustained multiple injuries, was hospitalized in serious condition. The tire and rim, while traveling through the air, caught Everett G. Spence, 33, of North Terre Haute, Indiana, who was seated on a truck in the infield on turn two, and knocked him back onto another truck, inflicting fatal head injuries. |
| Floyd Roberts | Driver | May 30, 1939 | AAA | Indianapolis 500 | Race | Defending Indianapolis 500 winner Floyd Roberts was on lap 107, when Bob Swanson, who had just started relief driving for Ralph Hepburn, lost control of his car coming out of turn two and went sideways. Roberts's left front wheel came into contact with the right rear of Swanson's car, which ejected its driver before going up in smoke and fire, while Roberts's car shot through the turn's outer board fence and hurtled into the adjacent golf course. Chet Miller swung to the inside in trying to evade the wreck, but ripped through a fence and was thrown from his car when it overturned with two spectators being injured by flying debris. Swanson and Miller escaped with injuries as well, whereas Roberts died in Methodist Hospital. |
| Lawson Harris | Riding mechanic | September 20, 1939 | | Firestone tire test | Testing | Babe Stapp was rounding the first turn at approximately 116 mph (187 km/h), when a broken axle or tie-rod incapacitated the right front wheel of his car, which was rendered uncontrollable and crashed into a wall.

| Shorty Cantlon | Driver | May 30, 1947 | AAA | Indianapolis 500 | Race | Shorty Cantlon swerved to avoid Bill Holland's car, which had gone onto the inside grass and skidded back across the track. Cantlon's car went into the outside wall nearly head-on, causing him severe chest, leg and internal injuries. He died in the track hospital shortly afterward. |
| Ralph Hepburn | Driver | May 16, 1948 | AAA | Indianapolis 500 | Practice | Ralph Hepburn's Novi became loose and swerved towards the infield entering turn three. Hepburn tried to correct it as he drove over the infield grass, causing the car to turn sharply to the right, and it hit the outside wall head-on at approximately 130 mph (210 km/h). A physician on the scene said Hepburn died instantly from a skull fracture and crushed chest, and it took about twenty minutes to remove Hepburn's body from the car. |
| George Metzler | Driver | May 28, 1949 | AAA | Indianapolis 500 | Practice | George Metzler crashed in turn one. He died of a crushed chest and head injuries in Methodist Hospital six days later. |
| Chet Miller | Driver | May 15, 1953 | AAA | Indianapolis 500 | Practice | After practicing all day, at 3:15 p.m., Chet Miller was clocked with a lap of 138.46 mph (222.83 km/h) in his Novi Special. Going into turn one, he went too low, and the left-front wheel got into the apron and the car started skidding. The back end came around, and the car crashed into the outside wall nearly head-on in a crash similar to Ralph Hepburn's in 1948. It rode along the wall and came to a stop on the south short chute. Miller died of a basilar skull fracture and a brain hemorrhage. |
| Carl Scarborough | Driver | May 30, 1953 | AAA | Indianapolis 500 | Race | During one of the hottest runnings of the 500, Carl Scarborough died of what was reported as heat prostration a short time after yielding his car to a relief driver on lap 70. According to speedway historian Donald Davidson, when Scarborough pulled into the pits, smoke or a small fire may have broken out on the car, which crews quickly doused with fire extinguishers. In the process, Scarborough may have inhaled CO$_2$, which may have contributed to, or been the actual cause of death. |
| Manny Ayulo | Driver | May 16, 1955 | AAA | Indianapolis 500 | Practice | Smashing into the concrete wall on the first turn, Manuel Ayulo sustained critical injuries. He died in Methodist Hospital the following day. |
| Bill Vukovich | Driver | May 30, 1955 | AAA | Indianapolis 500 | Race | Bill Vukovich, the two-time and reigning Indianapolis 500 champion, was leading the race when Rodger Ward broke his axle and spun his car on the backstretch near turn three, and came to a stop in the middle of the track. Behind him were Al Keller and Johnny Boyd. Keller, attempting to avoid Ward, swerved off the course, came back on and T-boned the car of Boyd, pushing it into the path of Vukovich, who was attempting to lap the other three drivers. Vukovich's car ran over the right rear tire of Boyd's, sending both into the air. Boyd's and Vukovich's cars struck the golf course bridge (which has been replaced with a tunnel), with Boyd's car striking upside down and Vukovich's striking driver's side up. After landing, Vukovich's car hit and went over the outer wall, sending it into a high-speed cartwheel outside the track. The car clipped a couple of spectators' vehicles and eventually came to rest upside down and in flames. Vukovich died instantly of a basilar skull fracture. |
| Keith Andrews | Driver | May 15, 1957 | USAC | Indianapolis 500 | Practice | Keith Andrews was hired as a back-up driver to Giuseppe Farina. While negotiating turn four, Andrews got too low and lost control of his car, which skidded 755 feet (230 m) before smashing against the end of the inside retaining wall tail-first. The back end of the car shoved Andrews up against the steering wheel, breaking his neck and killing him instantly. |
| Pat O'Connor | Driver | May 30, 1958 | USAC | Indianapolis 500 | Race | On the opening lap, a 15-car pileup occurred in turn three. According to A. J. Foyt, Pat O'Connor's car hit that of Jimmy Reece, sailed 50 feet (15 m) in the air, landed upside down, and burst into flames. Although O'Connor was badly burned in the accident, medical officials said that he was probably killed instantly from a fractured skull. Rookie Indianapolis 500 announcer Lou Palmer called the first-lap crash for the Indianapolis Motor Speedway Radio Network. Palmer had been placed in turn three because "nothing ever happens there". |
| Jerry Unser | Driver | May 2, 1959 | USAC | Indianapolis 500 | Practice | Coming out of turn four, Jerry Unser Jr. lost control of his car, which spun and hit the outside and inside walls. The fuel tank was punctured and the car caught fire. Unser was taken to the hospital with burns. He died of complications 15 days later. His death led the Speedway to require fireproof uniforms to be worn by all drivers while on the track. |
| Bob Cortner | Driver | May 19, 1959 | USAC | Indianapolis 500 | Practice | On Monday, May 18, Bob Cortner passed his rookie test. The next day, Cortner took to the track for a practice run. Johnnie Parsons, who observed the accident, reported that the wind was blowing hard and that Cortner got caught in a crosswind. The car slid to the infield before shooting back across the track head-on into the outside wall. Cortner's face hit the steering wheel and it appeared he began bleeding internally. He was pronounced dead that evening, the cause being listed as "massive head injuries". |
| William Craig | Spectator | May 30, 1960 | USAC | Indianapolis 500 | Race | Two spectators in the infield, Fred H. Linder, 36, of Indianapolis, and William C. Craig, 37, of Zionsville, Indiana, were killed, and as many as 82 were injured, when a homemade scaffolding collapsed. Approximately 125–130 patrons had paid a small fee ($5–$10) to view the race from the 30 feet (9.1 m) tall scaffolding, erected by a private individual (Wilbur Shortridge Jr.) and not the speedway—a practice that was allowed at the time. During the parade lap as the field drove by, the people on the platform began to lean and wave at the cars, which caused the scaffolding to become unstable. It soon tipped forward and fell to the ground, crushing people who were underneath the structure, and the 125–130 people who were on it either fell or jumped to the ground. Linder and Craig were pronounced dead of broken necks, and over 80 were injured, about 22 seriously. |

| Tony Bettenhausen | Driver | May 12, 1961 | USAC | Indianapolis 500 | Practice | Tony Bettenhausen Sr. was testing a Stearly Motor Freight Special for his friend Paul Russo. Down the main stretch, the car smashed into the outside wall of the track and then rolled 325 feet (99 m) along the barrier. The car came to rest entangled in the fence on top of the wall in front of Grandstand A, with the tail of the car on fire. Results showed the accident was caused by an anchor bolt which fell off the front radius rod support, allowing the front axle to twist and mis-align the front wheels when the brakes were applied. Bettenhausen was killed instantly. |
| John Masariu | Safety worker | May 30, 1961 | USAC | Indianapolis 500 | Race | When Eddie Johnson hit the inside wall in turn four, a fire broke out on his car. A safety fire truck arrived and the flames were put out. Retreating from the scene, the truck driven by John B. Williams accidentally backed over his friend, John F. Masariu, 41, of Danville, Indiana, the principal of Ben Davis Junior High School, who was clearing a path for the vehicle. Masariu died of a crushed chest. |
| Dave MacDonald | Driver | May 30, 1964 | USAC | Indianapolis 500 | Race | Coming out of turn four on lap two, Dave MacDonald spun and crashed into the inside wall. The car exploded and went back onto the track, into the path of oncoming traffic. Eddie Sachs hit MacDonald's car, and his car caught fire as well. Sachs died instantly from blunt force injuries from the impact, but his body was only slightly burned. MacDonald, badly burned, died two and a half hours later in the hospital, his lungs seared from flame inhalation, causing acute pulmonary edema. |

The chassis dug into the grass and flipped upside-down, slid a short distance and then flipped back over as it reached the pavement again and came to rest upright in the south chute. Pollard was rushed to Methodist Hospital, and pronounced dead at 10:50 a.m. His injuries were reported to include pulmonary damage due to flame inhalation, third degree burns on both hands, face and neck, a fractured right arm, a fractured leg, and a severe spinal injury. |
| Swede Savage | Driver | May 30, 1973 | USAC | Indianapolis 500 | Race | On the 59th lap, Swede Savage lost control as he exited turn four. His car twitched back and forth, and then slid across to the inside of the track at nearly top speed. It hit the angled inside wall nearly head-on. The force of the impact, with the car carrying a full load of fuel, caused it to explode in a plume of flame. The engine and transaxle tumbled end-over-end to the pit lane entrance while Savage, still strapped in his seat, was thrown back across the circuit. He came to rest adjacent to the outer retaining wall, fully conscious and completely exposed while he lay in a pool of flaming methanol fuel. Savage was taken to a hospital with critical injuries, but was in stable condition. A little over a month later, he died in the hospital on July 2, 1973. In 2006, Steve Olvey, who tended to Savage at the circuit medical center, wrote Savage's death may have been from contaminated plasma from a blood transfusion (contraction of hepatitis B which caused liver failure). Angela Savage, Swede's daughter, has gone on record to say that the cause of death was lung failure. |
| Armando Teran | Team member | May 30, 1973 | USAC | Indianapolis 500 | Race | Armando M. Teran, 23, of Santa Monica, California, was a pit crew member for Graham McRae. Just moments after McRae's teammate Swede Savage had an ultimately fatal crash in turn four, Teran started sprinting up the pit lane. At the same time, a fire truck was signaled to head to the scene. Cleon Reynolds, the chief of the Speedway Fire Department, signaled for fire-safety truck driver Jerry Flake to proceed northbound up the pit lane to the crash scene. Flake was stationed at the south end of the pits. Flake, driving northbound, struck Teran, whose body was tossed about 50 feet (15 m). Teran sustained crushed ribs and a fractured skull, and was pronounced dead at 4:23 p.m. The incident was witnessed by thousands of spectators, as it occurred on the pit lane right at the start-finish line. It was erroneously reported by media that Flake was driving the wrong way, and was at fault; at the time, safety trucks were permitted to drive in the opposite direction of the racing cars. The following year, USAC prohibited safety trucks from driving in the opposite direction. |
| Leroy Elwell | Spectator | May 26, 1974 | USAC | Indianapolis 500 | Pre-race | Seated in Grandstand A, Leroy C. Elwell, 64, of Palm Beach, Florida, died of heart disease before the beginning of the race. |
| Tim Vail | Spectator | May 22, 1980 | USAC | Indianapolis 500 | | On Carburetion Day, Timothy S. Vail, 19, of Indianapolis, was in the "Snake Pit" area, the turn one section of the infield (where the finishing turns of the road course for cars and the opening turns of the road course for motorcycles now stand), when he was stopped for trying to reenter the area after having stopped at an automotive service station to refuel his Jeep CJ. According to Speedway reports, with a no pass out policy, he attempted to reenter the area without paying, then swerved to avoid a puddle when his vehicle overturned (a common problem with these vehicles). Vail died of a fractured skull. His passenger David A. Stegenmiller, 19, of Indianapolis, was thrown from the vehicle, and sustained slight injuries. |
| Gordon Smiley | Driver | May 15, 1982 | USAC | Indianapolis 500 | Qualifying | On his second warm-up lap, Gordon Smiley's car began to oversteer while rounding the third turn, causing the car to slightly slide. When Smiley steered right to correct this, the front wheels gained grip suddenly, sending his car directly across the track and into the wall nose first at nearly 200 mph (320 km/h). The impact shattered the March chassis, which completely disintegrated, causing the fuel tank to explode, and sent debris — as well as Smiley's exposed body — tumbling hundreds of feet across the short-chute connecting turns three and four. Smiley died instantly from massive trauma. |
| Lyle Kurtenbach | Spectator | May 24, 1987 | USAC | Indianapolis 500 | Race | On lap 130, Tony Bettenhausen Jr. lost a wheel in the third turn. Moments later, Roberto Guerrero hit the tire with his nose cone, launching it into the air. The tire went over the catch fence, and into the top row of the "K" grandstand (where the current North Vista stand is located), striking in the head Lyle G. Kurtenbach, 41, of Rothschild, Wisconsin. Kurtenbach died in Methodist Hospital at 1:46 p.m. |
| Stephen White | Trespasser | May 29, 1991 | | | | Three days after the 1991 race, Stephen C. White, 31, of Indianapolis, entered the grounds of the speedway early on Wednesday, May 29. At some point before 7:30 a.m., he started driving around the track in a GMC pickup truck. He completed three or four laps, approaching speeds of 100 mph (160 km/h). In an attempt to stop White, Luther Wray, a foreman in the speedway's maintenance department, parked a Dodge Caravan minivan on the track near the start-finish line. White was driving approximately 90 mph (140 km/h) when he struck the van. The impact launched the truck into the air, traveling approximately 150 feet (46 m) before landing. White was pronounced dead upon arrival at Methodist Hospital. |
| Jovy Marcelo | Driver | May 15, 1992 | USAC | Indianapolis 500 | Practice | Jovy Marcelo's car snapped around at warmup speed and impacted on the right side entering turn one at 172 mph (277 km/h). Marcelo was killed instantly by a basilar skull fracture. |
| Scott Brayton | Driver | May 17, 1996 | USAC | Indianapolis 500 | Practice | Scott Brayton had won the pole position for the 1996 Indy 500 on Saturday, May 11. At 12:17 p.m. on Friday, May 17, Brayton, testing a back-up car, did a half-spin in the middle of turn two, the car scrubbing off almost no speed as it spun. Its left side impacted the wall at over 200 mph (320 km/h), and the force was such that Brayton's head also impacted the wall. The car slid 600 feet (180 m) to a stop down the backstretch. The driver was found unconscious in the car, and was transported immediately to Methodist Hospital. He was pronounced dead at 12:50 p.m. EST, having been killed instantly by a basilar skull fracture. It was determined that Brayton likely ran over a piece of debris in turn four or on the main stretch, which punctured his right rear tire. Unaware of the debris, he completed the lap at 228.606 mph (367.906 km/h), then drove into turn one. The tire suffered rapid deflation in turn two, causing the car to go out of control. |
| Tony Renna | Driver | October 22, 2003 | IRL | Firestone tire test | Firestone tire test | Tony Renna had just recently signed with Chip Ganassi Racing for the 2004 season. Firestone was conducting an end of season tire test for the 2004 race on October 21-22, 2003. Reigning series champion Scott Dixon completed the first day of testing without incident, and the Ganassi team was changing the car over for Renna in order for him to test on the second day that evening. On the second day, it was about 50 °F (10 °C) air temperature, and the track surface cool. On Renna's fourth lap, he was driving approximately 218 mph (351 km/h) and spun out in turn three. While spinning, his car caught air underneath the chassis, which lifted into the air, and into the catch fence. Renna died instantly of massive internal trauma, and was pronounced DOA at Methodist Hospital in Indianapolis. The exact cause of the spin was unknown, and damage was observed to have been inflicted to the grandstand seating (which was vacant) in the immediate vicinity of the impact area. The investigation into this crash led to series regulations on minimum ambient and surface temperatures and a requirement that cameras be active at all times when there is a test, practice, qualifying, or race session. |
| Art Morris | Safety crew member | August 6, 2004 | NASCAR | Brickyard 400 | | Arthur E. Morris, 64, of Anderson, Indiana, was a 20-year Safety Patrol seasonal employee. In the infield at approximately 7:30 a.m. on a practice day, he had a heart attack causing him to crash his motor scooter into a concrete wall. Having sustained head and arm injuries, Morris was admitted to Methodist Hospital where he was pronounced dead at 10:30 a.m. |
| Peter Lenz | Rider | August 29, 2010 | AMA/USGPRU | Rev'It Moriwaki MD250H | Race | On the warm-up lap of race two of the USGPRU Moriwaki MD250H Powered by Honda championship event, Peter Lenz, 13, lost grip in the front when the motorcycle contacted the curbing at the exit of Turn 4 in the motorcycle layout (the exit of the Snake Pit, which is Turns 1-4 for motorcycles or Turns 12-14 for cars), resulting in a low-side crash. The motorcycle fell on the left, while Lenz slid, sat upright, and waved to warn riders. Two riders were extremely close during the formation lap, causing Xavier Zayat, 12, to not see Lenz, leading to a collision between Zayat's motorcycle and Lenz. Paramedics immediately placed Lenz into a cervical collar, intubated him, and performed CPR. He later died of his injuries in Methodist Hospital. Zayat subsequently won the 2015 Nicky Hayden Award for road racing and retired in 2022, attending Yale University. |
