The Motorsport Commission, the committee responsible for all motorsport in Ireland, met to review the tragic events of last Friday at the Donegal International Rally, which left two marshalls dead.
They have issued a statement which said: "Having carefully considered all of the information available at this point of time, the Commission is satisfied that the agreed Safety Plan for the event was carried out in the correct manner.
"It is clear that what happened, whilst devastating in it's consequences, was an accident.
"The Motorsport Commission again extended it's deepest sympathies to the families and friends of George Clarke and Gerard McKenna.
"Motorsport Ireland officials will continue to work with representatives of the Donegal Motor Club and An Garda Siochana in the ongoing investigation.
"In the light of Friday's tragedy the Commission has taken a decision to review the current Safety Plans for all upcoming events.
"Safety of both spectators and competitors is of paramount importance in motorsport. To that end Motorsport Ireland has a Safety Review Committee which is currently looking at all aspects of safety in rallying.
"They have been directed to examine the circumstances of Friday's accident in their review which is due to be completed in September this year."
