The FIA is working with Formula One teams to make pit stops safer following a spate of unsafe releases in recent races.
Both Haas cars retired from the Australian Grand Prix with cross-threaded wheelnuts before a Ferrari mechanic suffered a broken leg when Kimi Raikkonen was released from a pit stop too early in Bahrain. There have also been unsafe releases during practice sessions since the start of the year, as well as an issue that saw a wheel come off Fernando Alonso's McLaren in testing.
"I think we can introduce a few things to decrease the likelihood of mistakes," FIA race director Charlie Whiting said.
