3. Historic Categories 1, 2, 3, 4 and 5
3.1. A valid Historic Rally Vehicle Identity Form( HRVIF)( or FIA Historic Technical Passport( HTP) issued by an FIA registered ASN, as appropriate), in addition to a CCLB / Vehicle Passport must be obtained from the ASN and both must be presented at scrutineering. No Vehicle is permitted to compete on an Event unless those documents are presented at scrutineering. The HRVIF is the definitive document for the technical specification of the vehicle for which it has been issued.
3.2. The HRVIF will remain valid for a period of 10 years from the date of issue and must be renewed whenever the registered owner of the Vehicle changes.
3.3. Vehicles in any of the Categories registered after the appropriate date may be permitted to hold an HRVIF in the absolute discretion of the ASN. An applicant for HRVIF for such a car must provide documentary evidence to the ASN Technical Department with the identity form application to show that the specific Vehicle( not model) was manufactured within the specified period. This evidence will include any technical documentation supplied by the manufacturer and any documents relative to the Vehicle and any information available concerning Chassis and engine numbers and any other details from reliable and authenticated sources as may be available. On receipt of satisfactory evidence the ASN may issue an Historic Rally Vehicle Identity Form which must be presented at scrutineering with the registration document in accordance with Art. 2.2 above.
3.4. Category 3, Category 4 and Category 5 Vehicles must also present their Homologation forms at scrutineering.
3.5. Upon issue of the validated HRVIF the applicant will be issued with two individually numbered ASN Registered Historic Rally Vehicle stickers( see App. 23 Drawing Number 3). These stickers are a visual affirmation of conformity with these Regulations and therefore must be affixed to the Vehicle one per side located on the rear section of the front wing and failure to respect this requirement is a breach of these Regulations and will render the Vehicle ineligible to compete and the Competitor subject to Judicial action.
