Our RTVs are run under the auspices of the MSA. The MSA publish the rules we operate under, and also insure us during the event.
We apply to the MSA for a permit for each RTV. All sorts of motor sports events are run on similar permits, which the MSA have been issuing since 2000. In 17 years they have now passed the 100,000 mark! The 100,000th such event was an Autotest run by Bridgend Auto Club in October last year.
