Red Bull and Ferrari broke the curfew last night in Montreal. The mechanics of the first two teams in the championship were in their garages in the evening, which is prohibited by the regulations. Indeed, it is not authorized to work on the single-seaters the day before the first free practice during a period of 13 hours.
In Canada, this period extended from Thursday evening at 8 p.m. to Friday morning at 9 a.m. (local time). The FIA has warned the two teams, but this is only the first prank for Ferrari and the second for Red Bull after Saudi Arabia when eight are tolerated by teams for the season.
