During a caution flag at the Daytona 500, something broke on Juan Pablo Montoya’s car. He spun hard into a safety truck, and the collision caused an instant explosion. Jet fuel — the safety truck held 200 gallons of kerosene — poured down the surface of Turn 3 at Daytona International Speedway after the accident.
