California ProKart Challenge

2025 K1 Circuit March Pit Passes and E-Waivers
As part of an overall effort to expedite driver check-in, we have eliminated the use of handwritten "Will Call" lists, although purchasing your tickets via Eventbrite below serves the same purpose. A few things will help us help you.
  •  Walking up to the Registration check-in desk WITH a printed copy OR your phone open to your BAR CODE is the quickest and easiest way to get you into the event. 
  • If you are not sure what the bullet above means, CHECK YOUR EMAIL! You should have received one from Eventbrite with the PDF barcode each time you purchase tickets. That is what we need to see AS YOU APPROACH the check-in area.
  • If you know the name of your MECHANIC or other attendee(s), please include their name(s) on their tickets. Adding their email address(es) will even send a copy directly to them. (NOTE: Mechanic passes are NOT automatically included with a driver’s race entry, nor can they be purchased with the entry through Motorsportreg.com. Only thru Eventbrite.)
  • If you don't know the name of your MECHANIC or other attendee(s), that's ok too – but you must send them a copy of their ticket. Even a screenshot of the barcode via text will work!
  • We can usually check someone in manually with a name look-up, but verification could delay their entry thru the gate -- so please make every attempt to provide them with their BAR CODED ticket.

Parents, Guardians and Team Principles

If you need to check in a driver for age or language reasons, you can still purchase a ticket for yourself below ahead of time – or you can purchase it at Driver Registration. Purchasing passes ahead of time below helps expedite check-in and keeps the lines moving faster.

E-Waivers

In addition to pre-purchasing your tickets below, we are now offering E-Waivers as a separate process while we evaluate integrated solutions that are compatible with our insurance carrier.  Once you purchase your tickets below, please make sure to complete the E-Waiver HERE. (If you are signing for a minor, please check the appropriate box on that form). This will create a credential with your picture that you can show at the Reg desk IN ADDITION to your Eventbrite ticket. We can look up your Eventbrite ticket so would prefer you present your E-Waiver Credential.

Please note: This is a LEGAL DOCUMENT so you must be clearly visible in your photo, similar to a passport or driver's license.
