Did not finish

In racing, did not finish (DNF) denotes a result of a participant who does not finish a given race, either because of a mechanical failure, injury, or involvement in an accident. This may also be used in cases where the competitor has hit the time limit for the race, especially in speedcubing.

The term is used in:

• Automotive racing such as Formula One; NASCAR; IndyCar; off-road racing, including buggy, trucks, kart, and UTVs, both desert and short-track
• Motocross and quad racing, both desert and short-track
• Horse racing
• Competitive cycling
• Competitive track and distance running
• Competitive snow skiing and snowboarding
• Speedcubing

Race participants try to avoid receiving a DNF, as some associate it with poor driving.
