Before every race, it is not only the cars which are checked by a team of officially appointed scrutineers. The team manager and drivers from each team must present themselves and all the necessary documents, licences and authorisations for Administrative checks. In sports car racing driver line ups do not always remain constant throughout the season, and it is therefore important that this takes place at every event to ensure that everyone complies with the regulations. Drivers must also present their equipment for checks including helmet, HANS device, fireproof race suits, boots and gloves.
