Autocross Guide & FAQ
Everything you need to know before your first SCCA Solo Autocross event with Delta Region.
What is SCCA Solo Autocross?
Autocross is a form of motorsports that emphasizes safe competition and active participation. An autocross is a timed competition in which drivers navigate one at a time through a defined course, racing against the clock rather than wheel-to-wheel with other cars.
Autocross is an accessible entry-level motorsport that provides a great stepping stone for drivers looking to sharpen their car control or move into other forms of racing. Skills learned on the autocross course directly translate to road racing as well as safer emergency handling on the street.
Courses are typically about a mile long and place demands on car handling, precision, and driver skill rather than raw engine power and outright speed. Courses are marked by traffic cones on a large paved area or motorsports skid pad, with classes that allow almost any vehicle—from economy sedans to purpose-built racing cars—to compete.
While top speeds usually do not exceed highway speeds, the activity level (measured in discrete turns and inputs per minute) can be higher than even Formula One due to the tight, technical elements packed into each course.
Delta Region Autocross
Delta Autocross events generally have the first car off around 10:45 AM on the day of the event and occur rain or shine (apocalyptic weather excepted). Event fees go towards covering site rental, sanctions and insurance, free water, chalk, cones, and club operations.
All Delta events are open to all drivers with an appropriate vehicle and valid driver's license or permit, as well as to spectators and riders over 12 years of age.
Additionally, Delta autocrossers are exceptionally friendly folks, and we love it when new people come out to race with us. (Except for the guy in the trailer behind the computer. He is a jerk, and he neither knows nor cares about your time.)
Delta provides loaner helmets to drivers who need them, and for all events we use an advanced electronic timing system with live Clokkr timing and Axware Autocross management software.
4 Simple Steps for Your First Event
Pre-Register on MotorsportReg
Sign up online before the event via our MotorsportReg link. Not sure what class your car is in? Ask in our Facebook group or select Novice and we'll help you at check-in.
Prep Your Car & Empty Loose Items
Remove all loose items from the cabin and trunk (floor mats, tools, water bottles). Check that your battery is securely tied down, tires have good tread, and lug nuts are tight.
Arrive Early, Tech & Walk the Course
Arrive by 8:00 AM so you have plenty of time to pass Tech Inspection, grab a free loaner helmet if you need one, apply your car numbers/class letters, and join the Novice Course Walk.
Drive One Heat, Work One Heat
Autocross is volunteer-powered! When your heat isn't driving, you'll help reset knocked cones on course or assist in grid—the best seat in the house to watch other lines.
