The FIA has released a list of the messages that will and will not be allowed to be sent to drivers as part of its clampdown on team radio.
Last week Charlie Whiting issued a directive to the teams informing them that the FIA would be banning messages aimed at improving a driver's performance
by rigorously enforcing Article 20.1 of the sporting regulations which states: "The driver must drive the car alone and unaided."
Following comments from the likes of Toto Wolff that the FIA's stance was a “controversial” one, the governing body has now issued a more definitive list of which messages will be allowed and which ones will be considered a breach of regulations.
- Acknowledgement that a driver message has been heard.
- Lap or sector time detail.
- Lap time detail of a competitor.
- Gaps to a competitor during a practice session or race.
- "Push hard", "push now", "you will be racing xx" or similar.
- Helping with warning of traffic during a practice session or race.
- Giving the gaps between cars in qualifying so as to better position the car for a clear lap.
- Puncture warning.
- Tyre choice at the next pit stop.
- Number of laps a competitor has done on a set of tyres during a race.
