Driver Age
ALL driver’s ages must be verified prior to completing the processing of their race entry and/or SKUSA membership. Verification would be a clear and official legal copy of his/her birth certificate or passport. Adult driver’s licenses will work, as well, but we prefer one of the other 2 official documents, if available.

SKUSA has many of the previous driver’s birth certificates on file, but mostly just those under 18. If not, you must attach an ‘Age Verification’ document to the online driver’s MSR application,  or send it via email to This e-mail address is being protected from spambots. You need JavaScript enabled to view it or fax to (951) 491-0809 with the application for a SKUSA membership/racing license. Be sure to check the Classes section of this event for more information, and sections 15.3 and 20.1.2 of the SKUSA Rulebook for minimum age requirements of each class.
