Following Sergio Perez’s win in Monaco and Max Verstappen’s third-place finish, Ferrari protested both drivers for crossing the pit exit line during an early tyre change in the race. The FIA investigated the matter afterwards but ultimately concluded that neither driver had committed an offence. The investigation revealed that Perez had not touched the line, whereas Verstappen crossed the line slightly.
The decision to clear Verstappen was due to a change in wording in the FIA’s International Sporting Code, which now states that drivers “must not cross” the line. The stewards deemed that Verstappen had not crossed as his wheel did not fully breach the line. However, this interpretation led to concerns from drivers about potential safety implications. As a result, the FIA revised the wording of its International Sporting Code to clarify the rule for crossing the line.
The revisions have been approved by the World Motor Sport Council and communicated to teams and drivers ahead of the Bahrain Grand Prix. The new wording now specifies that the limit for crossing the line is judged based on the outer edge of the tyre. Henceforth, the outside of any tyre should not exceed the outside of the relevant line painted on the track. The new rule also applies to pitlane entry lines. Niels Wittich, F1 race director, included a drawing in his pre-race Event Notes in Bahrain to illustrate where the new limits are.
