The F1 Rule That Stops Haas From Using a Fifth Driver

Haas faces the final stretch of the season with a problem that few fans knew about: the FIA regulations limit to a maximum of four different drivers per team in a single season. The American team has already exhausted that quota, after having fielded Oliver Bearman and Esteban Ocon as full-time drivers and Ryo Hirakawa and Rafael Câmara as substitutes. A situation that in principle should not be an obstacle but that leaves the team without room for maneuver in the face of any unforeseen event in the three races that remain.

The rule, introduced in 2004, sought to bring order to an era in which teams changed drivers too frequently. Before that modification teams like Prost came to use five different drivers in a single season, with Jean Alesi, Gastón Mazzacane, Luciano Burti, Heinz-Harald Frentzen and Tomas Enge. Since then no one had exceeded that limit again, except Toro Rosso in 2017 and 2023. Now Haas faces a juncture that could test the FIA's flexibility.

The immediate problem is the Las Vegas Grand Prix. Haas will have to decide who accompanies Bearman in the car, the most logical option is Ryo Hirakawa who already replaced Ocon in Mexico and who is free after being proclaimed WEC champion with Toyota. Rafael Câmara, the other candidate, has commitments in Formula 2 where he leads the championship and is playing for the title in Qatar and Abu Dhabi, the decision therefore will depend on the team's priorities and the Brazilian's aspirations in the silver category.

The real headache would come if Bearman could not participate in any of the three remaining races. In that scenario Haas would be forced to field Câmara and Hirakawa during that weekend or to consider the return of Ocon, a possibility that seems remote after his abrupt departure from the team. Article B1.7.1 of the regulations contemplates the possibility of making an exception in situations of force majeure, but the team prefers not to have to resort to it.

The regulation conceived to prevent teams from resorting to an excessive number of drivers throughout the year, has become a headache for Haas at the worst moment. With Bearman as the only confirmed full-time driver and two substitutes who alternate according to their commitments the team needs nothing to go wrong in Las Vegas, Qatar and Abu Dhabi. Any setback would force the FIA to evaluate an exception for force majeure, a scenario that Haas prefers to avoid at all costs.

Haas's situation is a reminder that Formula 1 is not only governed by what happens on track, the regulations with their lights and shadows, condition the teams' decisions and can become an unexpected obstacle. Haas has managed the season wisely but now must navigate carefully so as not to be trapped by a rule that limits its capacity for reaction.

The three races that remain will be an exam of foresight and management for a team that despite the difficulties, continues fighting for its objectives in the championship.
