Autocross events are low to medium speed car control events. Most events are held in large parking lots or airports but some events are held on race tracks and go-kart tracks. Courses are created using traffic cones, and sometimes outlined in chalk to help with visuals. Drivers take to the course one at a time with results determined by comparing each drivers time to complete the course. Penalties are given for significant contact with a cone or if a competitor misses part of the course.
