|With effect from 1 July 2004, the regulations governing the use of SOS/OK boards in rallying have been amended to reflect those of the FIA. After an accident, the crew must display the red SOS sign if urgent medical attention is required, or the OK sign to indicate no assistance is necessary. Any following car that has the SOS sign displayed to them, or that sees a car where both crew members are still in the car but is not displaying a sign, must immediately and without exception stop to render assistance. All other cars following shall also stop, except the second car, which shall continue to the next radio point to report the accident. The same regulation was also approved for Off Road events from 1 July 2004, with a small variation that does not require a safety triangle to be placed before the scene of the accident.
