The tragic car crash that claimed the life of Princess Diana on August 31, 1997, has been the subject of extensive investigations over the past decades, uncovering disturbing evidence about the conditions leading up to the accident.
The thorough examinations of the wreckage and surrounding circumstances paint a grim picture that is still chilling.
One of the most significant findings was that the Mercedes carrying Diana and her companion Dodi Al Fayed collided into a pillar inside the Pont de l'Alma tunnel in Paris at speeds far exceeding the legal limit. The speedometer needle was reportedly jammed at around 95 to 110 km/h (59 to 68 mph), almost twice the speed limit of 50 km/h (31 mph). This excessive speed was a critical factor contributing to the fatal crash.
French investigators also found that the driver, Henri Paul, was intoxicated at the time of the crash, having consumed alcohol and antidepressants. His impaired condition severely compromised his ability to control the vehicle. Toxicology tests conducted both immediately after the accident and during the autopsy confirmed the presence of alcohol and drugs in his system, though he was not deemed legally drunk.
Additionally, forensic experts discovered that the car had made contact with another vehicle—a white Fiat Uno—shortly before the crash. Paint traces found on the Mercedes confirmed this collision, although the exact driver of the Fiat Uno was never conclusively identified despite exhaustive police efforts. This interaction is believed to have contributed to the loss of control that caused the fatal crash.
The crash investigation also revealed failings that compounded the tragedy. The passengers in the Mercedes were not wearing seat belts, which likely increased the severity of their injuries. Princess Diana herself suffered catastrophic internal injuries, including a severe heart injury caused by trauma during the collision. Despite prompt medical attention, her injuries were deemed unsurvivable under the circumstances.
