What Is a DNF in F1? Did Not Finish, Explained

DNF means 'Did Not Finish.' It is used in the results to show that a driver took the start but retired before completing the race, whether from an accident, an engine or gearbox failure, a puncture, or damage that made the car undriveable. A DNF is different from DNS ('Did Not Start') and DNQ ('Did Not Qualify'), which happen before the race begins.

Almost never. Because championship points are awarded only to the top ten classified finishers, a driver who records a DNF usually scores zero. The rare exception is if enough cars ahead also retire and the driver has completed 90% of the race distance, in which case they can still be classified in a points position despite stopping. See our guide to the F1 points system.

Historically the two biggest causes are collisions — often first-lap incidents — and mechanical failures such as engine, gearbox, hydraulic or power-unit problems. Punctures, brake failures, and crash damage from contact also feature. In the modern era reliability has improved dramatically, so accidents cause a larger share of DNFs than they once did.

Not always. If a car retires but has already completed at least 90% of the race distance, the driver is classified in the finishing order at the position they held, even though they did not cross the line running. This rule rewards drivers who nurse a wounded car close to the end, and it can turn what looks like a DNF into championship points.

A single DNF can swing a title fight because it usually means losing a full haul of points to a rival who finishes. Over a season, a driver or team with poor reliability or frequent incidents falls behind even if their car is fast on pace. This is why teams value finishing races, and why a run of DNFs is often more damaging than a run of low-points finishes.

A DNF ends a driver's race entirely. A [drive-through penalty](/what-is-a-drive-through-penalty-in-f1/) is an in-race punishment where the driver loses time by driving through the pit lane but continues racing. One is a retirement; the other is a time loss. A severe enough problem that follows a penalty can, of course, still lead to a DNF later in the same race.

Yes. A car can retire at any point in a race, including during a [safety car](/f1-safety-car-explained/) period — for example if earlier damage forces it to stop, or a failure develops while circulating slowly. The DNF is recorded whenever the car leaves the race for good, regardless of whether the race is running at full speed or neutralised.
