When Oscar Piastri drove his first FP1 session for Alpine in 2022, he had never run a current F1 car in a competitive weekend environment. The session was his first real opportunity to feel the tyre temperatures, braking forces, and steering weight that no simulator can fully reproduce. By the time he secured a corrida seat at McLaren for 2023, that FP1 mileage — along with other test opportunities — had given him a baseline that made the transition to full-time racing less of a shock.
That is the intent behind the FP1 rookie rule. In an era of severely limited testing, it forces teams to create track time for the next generation. But the rule carries a real competitive cost for the teams that must give up a practice session to comply.
What the FP1 Rookie Rule Requires
The rule mandates that each equipe must field an eligible young or inexperienced piloto in a set number of FP1 sessions per temporada. The current requirement is two sessions per car per year, which means a two-car equipe must provide at least four FP1 opportunities across the temporada.
The piloto must hold a valid FIA super licence and meet the eligibility criteria — primarily that they have started no more than two Grand Prix races. This ensures the sessions go to drivers who genuinely need the experience, not to established corrida drivers or equipe principals doing a promotional run.
The sessions count as official Grand Prix weekend practice. The rookie uses a corrida car, runs on the same track as the rest of the field, and generates data that the equipe can use for the rest of the weekend. The difference is that the regular corrida piloto must sit out, losing 60 minutes of practice time at a circuito they may be learning or where the car needs setup work.
Who Counts as Eligible
The eligibility criteria focus on corrida experience rather than age. A piloto who has started two or fewer Grands Prix is typically eligible, even if they have extensive experience in junior categories or other series. This prevents a situation where a piloto who made a one-off substitute appearance loses their eligibility entirely.
The super licence requirement is separate. The rookie must have accumulated enough points through junior category results to qualify for a super licence, or hold one through other qualifying criteria. This means the pool of eligible drivers is relatively small — typically current reserve drivers, Formula 2 contenders, or drivers transitioning from other series who have met the FIA's points threshold.
How Teams Choose Which Sessions to Sacrifice
Not all FP1 sessions are equally valuable to a corrida piloto. Teams typically look for weekends where the cost of losing FP1 is lowest:
Circuits the piloto knows well: If the corrida piloto has years of experience at a particular track, losing one practice session there is less damaging than at a new circuito where every lap matters for learning.
Non-sprint weekends: On a standard weekend, teams have three practice sessions before qualifying. On a sprint weekend, there is only one practice session before the sprint qualifying format begins. Losing FP1 on a sprint weekend is much more costly, so teams generally avoid using rookie sessions there.
Early-temporada rounds: Some teams prefer to use their rookie allocations early in the temporada, when the car is still being understood and the data from any piloto — even a rookie — contributes to the overall learning process.
Favorable conditions: Dry, consistent weather makes FP1 running more predictable and useful for a rookie. Chuva or variable conditions make the session more difficult to manage and reduce the data value for the equipe.
Why FP1 Is Difficult for Rookies
FP1 looks calm compared with qualifying or the corrida, but the demands on a rookie are significativo. The piloto has limited laps to learn the circuito in an F1 car, adapt to the braking points and corner speeds that are far beyond what they experienced in junior categories, and complete the equipe's run program without mistakes.
The equipe has a structured plan for the session — usually a combination of aero correlation runs, baseline setup work, and tyre data collection. The rookie must execute that plan while also managing traffic, radio procedures, steering wheel settings, and tyre warm-up cycles. Every off-track excursion or spin costs track time that cannot be recovered.
The pressure is also different from a corrida weekend in a junior category. The rookie is sharing a garage with a corrida piloto who needs the car prepared for FP2. Any damage or delay affects the corrida piloto's program too.
What Teams Get Back
The session is not purely a cost. A well-prepared rookie can provide useful data on tyres, balance, and track conditions. Some teams use the opportunity to run sensor packages or aero rakes that the corrida piloto would not normally carry, because the rookie's run plan can be structured around data collection rather than peak lap time.
The rule also accelerates the development of junior drivers who may become future corrida drivers. In an era where pre-temporada testing is limited to three days and in-temporada testing is virtually eliminated, FP1 is one of the few opportunities for a young piloto to gain meaningful F1 experience before being thrown into a corrida seat.
For the teams' academy programs, the FP1 requirement provides a tangible milestone. A junior piloto who has completed FP1 sessions has demonstrated that they can operate within an F1 weekend environment — a meaningful step up from simulator work and private tests.
Why the Rule Remains Controversial
The rule has critics. Some argue that forcing teams to give up competitive practice time is an unnecessary burden, particularly for smaller teams that cannot afford to lose any track time. Others argue that the requirement does not go far enough — two sessions per car per temporada is a small concession compared with the unlimited testing that previous generations of drivers enjoyed.
The balance point is that the rule creates opportunity without imposing excessive cost. Teams choose which sessions to use, they control the run plan, and they retain the data. The rookie gets real experience, and the sport gets a pipeline of drivers who have at least some exposure to F1 machinery before they arrive on the Grid full-time.
