These rules are NEZ competition rules for Formula Offroad. These rules are revised each fall if requests for change of rules come from member countries competition boards/ASN's. Proposals for change of rules should be sent to before September 1st and NEZ-FOWG will review the proposals and try to issue regulation changes before November 1st if changes will be approved.

As no changes were made to rules between 2017 and 2018 the 2017 rules will also be used in 2018.
