One day from any of the pre-season tests, no less than 20 days before the start of the first round of the championship, must be set aside for testing of wet-weather tyres, arrangement of which 'will be made by the appointed tyre supplier in full consultation with the teams and the FIA'.
Any team substituting a driver with another 'who has not participated in an F1 race in the two previous calendar years' will be permitted one day of TCC under certain guidelines, including not taking place on a circuit hosting a race in the current calendar, and occurring with a 28-day period of the substitution. Should the proposed substitution not subsequently take effect, the team will lose a day of pre-season testing the following year.
In confirming that no testing can take place in August, the FIA also reinforced the 'summer shutdown' between the Hungarian and Belgian grands prix. Teams notify the FIA of their intended shutdown period prior to the start of the championship season.
