You must have an X on the back of your helmet and you must attend all novice drivers meetings. The above rules apply to all NCK races.

    4. If you break down and out for the day you must take your kart to the scales. The scales staff will verify your broken condition to apply for a rollover credit.
    5. NCK will NOT ACCEPT VERBAL / EMAILED REQUESTS FOR ROLLOVERS! You must fill out the rollover request form, have a NCK BOD member sign it, and then return it to the scales. Forms are available at the scales.
