Following Lewis Hamilton and Max Verstappen's coming together at the British GP, F1 teams have been warned they risk punishment if their personnel speak with race stewards during ongoing investigations without prior approval.
The Briton took the chequered flag in front of his home fans but it wasn't without controversy, as he came together with the Red Bull driver on the opening lap. The incident resulted in a red flag, at which point both Toto Wolff and Christian Horner lobbied the stewards as they looked into the matter.
While Masi initially said he had no problems with teams speaking to stewards, that looks to have changed with Autosport reporting that teams have been warned that unprompted visits to the stewards will no longer be allowed.
Masi is said to have sent a note to all competitors telling them that stewards will only be available to those with prior approval or those that have been summoned.
If teams are found to be in breach of this they could face sanctions, which range from a simple reprimand all the way to a disqualification.
