DNF
Race Procedures
DNF stands for "Did Not Finish," indicating that a competitor started a race but failed to complete it.
In motorsport results, a DNF appears next to a driver's name when they're forced to retire from a race before reaching the checkered flag. Common causes include mechanical failures (like engine or transmission problems), crashes, or occasionally driver illness. A DNF typically results in zero championship points for that event.
While DNF is universal across racing disciplines from Formula 1 to NASCAR and MotoGP, specific rules may vary. For example, in Formula 1, drivers completing over 90% of the race distance before retiring are still classified in the results, though marked as not finishing.
