F1’s ruling body agreed on Sunday to a last-minute relaxation of restrictions on team radio just an hour before the start of the 2016 Formula 1 Rolex Australian Grand Prix.
The International Motoring Federation (FIA) eased the rules to allow drivers and teams to discuss their strategy by radio during the race.
After agreeing to review the matter, the FIA’s official Race Director Charlie Whiting met the teams and said that previous limits regarding strategies were now lifted.
In a list of allowable messages, Whiting wrote that teams could discuss: "The driver's own race pit stop strategy as well as those of his competitors, this is limited to the timing of pit stops and which tyres will be (or have been) used.
"For the avoidance of doubt, no car or power unit set up may be included in any such strategy discussion."
The FIA had previously said that it intended to enforce, rigorously, article 27.1 of the sporting regulations that state.
This states that "the driver must drive the car alone and unaided.”
