F1's teams have been warned they risk penalties if personnel visit the stewards at a race in future without being invited. FIA race director Michael Masi wrote to all 10 teams in the wake of Sunday's British GP to clarify that visiting the stewards, who decide on incidents on the track and determine any penalties, will only be allowed by prior approval or official summons.
