To be classified is the formal result as recorded by the FIA. Official places are recorded for qualifying and finishing.

You are classified, and recorded, as a finisher if you complete more than 90% of the race distance. The race distance may be amended if there is a red flag and points will be allocated under a sliding scale points system

Cars that do not finish due to crashing or mechanical failure are recorded as DNF (Did Not Finish).
