32. General Car Requirements

No signal of any kind may pass between a moving car and anyone connected with the car's Competitor or driver, save for the following:

  • legible messages on a pit board;

  • body movement by the driver;

  • lap trigger signals from the pits to the car;

Lap marker transmitters must be battery-powered and, once operating, must be free-standing (not attached to any other pit equipment by means of wires or optical fibres) and incapable of receiving external information. Such lap triggers must use a transmitter operating with a carrier frequency above 10 GHz (radio or optical) and a beam half angle of no more than 36° when measured at the 3dB point, and must not be used for the transmission of any data from pit to car other than the lap mark. Lap mark data must be transmitted repeatedly and must be demonstrably consistent;

  • verbal communication between a driver and his Team by radio;

  • Telemetry: one-way (car to pit) telemetry is allowed.

IMPORTANT: no item, installation or antenna is permitted which may interfere at any time with the Official data logger, timing, GPS, radio or TV systems.

Provisional permission is given for two-way radio communications using approved voice over IP systems for the 2024 season. Data is only allowed from car to pits. Should any interference be reported on any of the official channels, including TV, Timekeeping including track limits, Lumirank, and all forms of telemetry (GPS, TPMS, Data Logger, RSTL etc) this permission will be immediately revoked. Approval for any such systems must be requested from the Sporting Board.

No equipment may be positioned on top of the pit wall or any adjacent structure, unless securely fixed to the satisfaction of the Officials. Any such equipment cannot protrude from the wall on the track side.

Electromagnetic radiation between 2 and 2.7 GHz is forbidden, save with the written consent of the Promoter.
