After collecting the pass, it will be necessary to go inside the Circuit to the booths by the Race Direction Tower to fill out the liability waiver and pick up the required material for entry to the track (car sticker, driver and eventual passenger wristband, receipt of payment or payment of the registration fee).
For a faster procedure, you can download and fill out the form at home and bring it with you: you will only have to sign it at the Race Direction Tower.
