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 only counted for Australia because he made his F1 debut in Abu Dhabi last year.
This Friday at Barcelona, ex-Alpine junior turned Williams Academy Driver Victor Martins will take over Alex Albon's FW47 while Ryo Hirakawa will make his third FP1 appearance.
