All adult attendees, whether driving or observing, must sign a waiver form to be on the autocross site. Minors must comply with current PCA regulations regarding observing and likewise for any 16- and 17-year-old entrants in the Junior Participation Program. All participants at an autocross event must comply with all rules set forth by the autocross and safety chairs or other PCA officials. All vehicle occupants while on course must provide and wear an approved helmet. Helmets built to Snell Foundation standards or other standards such as FIA 8860, SFI 31.1 and BS6658-85 Type A-FR are approved for use. Approved helmets must be manufactured to the current rating or the two most recent SA, M or K Snell ratings. For example, if the current Snell SA standard is SA2020, helmets meeting SA2020, SA2015 and SA2010 are allowed.

The complete set of rules governing autocross and other competitive events held at PCA’s annual Parade are updated for each year. To learn all the details of an autocross event, see pages 15-32 in the 2025 Parade Competition Rules document. The Shenandoah Region may need to adjust these autocross rules to accommodate attendance or setting, but these will give you an excellent understanding of the event.
