The FIA has sent a further technical directive to the Formula 1 teams to confirm that the recently announced radio message restrictions will also extend to pit board signals.

FIA Race Director Charlie Whiting issued a three-page document to all teams that listed precisely what information can and cannot be shared with their drivers while they are on the circuit.

Under the expanded guidelines, drivers cannot be told where they are faster or slower than another driver, will be unable to receive messages instructing them to change a setting via their steering wheels or be given information on what adjustments they need to make to their fuel consumption.

From the Japanese Grand Prix onwards, a further clampdown will be introduced whereby teams will be unable to communicate updates on tyre pressures or temperatures, or warnings on brake wear or temperatures.

That doesn’t exclude every form of communication, and there’s still a lot of information which can be given, such as lap or sector time detail, the lap times of another driver, the time gap to another driver, tyre choice for the next stint, tyre puncture, damage warnings, whether certain flags are being waved, the deployment of the Safety Car and the state of the track surface.

The FIA has provided a full list of what is in and out of scope as follows:

Not allowed:

  • Sector time details of a competitor and specific information where a competitor is faster or slower.
  • Adjustments to power unit settings.
  • Adjustments of gearbox settings.
  • Information on differential settings.
  • Balancing the battery charge states or adjusting for performance.
  • Information on fuel flow settings (unless if requested to do so by Race Control).
  • Information on level of fuel saving needed.
  • Information on tyre pressures or temperatures (enforced from the Japanese Grand Prix onwards).
  • Discussions about clutch position and engine mapping for race start and pit stops.
  • Information on clutch maps or settings, e.g. bite point.
  • Instructions to perform burn-outs prior to race starts.
  • Information on brake balance or brake-by-wire settings.
  • Warning on brake wear or temperatures (enforced from the Japanese Grand Prix onwards).
  • Instruction to reset to default settings (other than in the case of a clearly identified problem with the car).
  • Answering a direct question from a driver, e.g. “Am I using the right torque map”?
  • Any message that appears to be coded.


  • Confirmation that a driver message has been heard/acknowledged.
  • 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”, etc.
  • Helping with warning of traffic during a practice session or race.
  • Communicating gaps between cars in qualifying so as to better position the car for a clear lap.
  • Puncture warnings.
  • Tyre choices at an upcoming pit stop.
  • Instructing or suggesting when to pit for a tyre change
  • The number of laps a competitor has done on a set of tyres during a race.
  • What tyre compounds a competitor is running.
  • Indication of a potential problem with a competitor’s car during a race.
  • Information concerning a competitor’s race strategy.
  • Yellow flags, blue flags, Safety Car deployment or other cautions.
  • Team orders

The FIA has confirmed that it will not be issuing warnings to teams who are breaching the technical directive governing Article 20.1 of the FIA Formula 1 Sporting Regulations, and that its Stewards would immediately impose sanctions as required.
