Dale Earnhardt died from a basilar skull fracture caused by blunt-force trauma to his head in a crash on the final lap of the 2001 Daytona 500.

Quick Scoop: What did Dale Earnhardt die from?

On February 18, 2001, during the last lap of the Daytona 500 at Daytona International Speedway, Dale Earnhardt’s car made contact with another car, shot up the track, and hit the concrete retaining wall at high speed and a sharp angle.

The impact forces were extreme (estimated around 60 G), and although the car didn’t appear as catastrophically destroyed as some other crashes, the energy went straight into his body.

Doctors determined that the fatal injury was a basilar skull fracture, which is a break at the base of the skull where it meets the spine.

This type of fracture can cause massive internal bleeding and brainstem damage and is often instantly fatal, which is why he was pronounced dead shortly after arriving at Halifax Medical Center.

Investigations later concluded that several factors contributed to how deadly the crash was:

  • The speed and angle of impact with the wall.
  • A prior collision that left him slightly out of position in the seat.
  • Separation of the left lap belt, which allowed his body and head to move more violently inside the car.

His death, along with similar basilar skull fracture deaths in that era, pushed NASCAR into a major safety overhaul, including widespread adoption of the HANS (Head and Neck Support) device and other cockpit and barrier upgrades to better protect drivers’ heads and necks.
