Petty is also remembered for three of the many incredible crashes that he survived: In the 1970 Rebel 400 at Darlington, Petty was injured when his Plymouth Road Runner cut a tire and slammed hard into the wall separating the track from the pit area. The car flipped several times before coming to rest on its side. This accident injured Petty's shoulder, and helped Bobby Isaac to win the 1970 Grand National Championship. During the accident, Petty's head hit the track pavement several times, which, along with Joe Weatherly's fatal crash six years earlier, led NASCAR to mandate the installation of the Petty-developed safety net that covers the driver's side window. In a 1980 race at Pocono, Petty slammed the Turn 2 wall, nearly flipping the car. Petty barely escaped breaking his neck in the wreck and kept his injury hidden from NASCAR officials for the next races, knowing that another wreck could possibly kill him. Such an incident is unlikely to happen now because of modern NASCAR rules requiring an official series medical liaison to clear a driver after a crash. In the 1988 Daytona 500, on Lap 106, Petty got turned by Phil Barkdoll out of turn 4. Petty's car caught air and tumbled many times and rode along the catch fence and hurled parts all over the front stretch at the Daytona International Speedway. After several flips, Petty got t-boned by Brett Bodine before coming to a stop. Petty walked away with no serious injuries, except for temporary sight loss due to excessive g-forces. The crash was similar to the accident suffered by Bobby Allison during the 1987 Winston 500 at Talladega Superspeedway and Carl Edwards 2009 Talladega crash in that all three cars became airborne after turning sideways, and both cars damaged the spectator fencing (though Petty's crash did much less damage to the fencing). Petty's car became airborne despite the use of the carburetor restrictor plate, which was mandated by NASCAR for races at Talladega Superspeedway and Daytona International Speedway just prior to the start of the 1988 season.
