Each Formula 1 team needs to satisfy the rule of running a ‘rookie’ driver twice in each of its cars during a season.
Rookies are defined as any driver with no more than one grand prix start to their name. So Kimi Antonelli (Mercedes) Isack Hadjar (Racing Bulls) and Gabriel Bortoleto (Sauber) all ticked off the rookie requirements for their cars in Australia and China.
As Ollie Bearman (Haas) already started three grands prix last year, he doesn't count, while Alpine rookie Jack Doohan could have counted for Australia because he made his F1 debut in Abu Dhabi last year, but Alpine already planned to use rookies for four sessions.
At Silverstone Arvid Lindblad (Red Bull) and Paul Aron (Sauber) will make their first practice starts of 2025.
