Since the 1990s
Churches started it. Parents wanted a Halloween with less gore, fewer strangers and no crossing busy roads in the dark, so congregations parked in a circle, opened their boots and handed out candy from the back. In car-dependent suburbs it simply worked better than a street of houses far apart — and a flat car park suits children with allergies, wheelchairs and strollers too.
Trunk or treat events in Libertyville run from Oct 25 to Oct 25, 2026: 1 event.
Yes: 9 more events are listed within reach of Libertyville, in Mundelein, Rockford, Hammond and Schaumburg and more. The soonest is Boo Bash (Ages 0–12 yrs) in Mundelein, on Sat, Oct 17.
A Halloween event where children go from car to car instead of door to door. Families park in one place — usually a church, school or community car park — open their boots, decorate them, and hand out candy from the back. It began at American churches in the 1990s as a safer, more contained alternative to trick-or-treating, and most now add a costume parade, games or a best-decorated-trunk contest.
Their costume, a treat bucket or bag, and something that glows — a glow stick or a small torch — because most events run after dark. Comfortable shoes help: a big car park is a lot of walking.
Pick a theme and fill the open boot with it. Monster mouths, pumpkin patches, haunted houses, outer space and under the sea are the favourites. Battery string lights matter most, since a car park has no sockets; then a backdrop, cobwebs or props, and a bowl of candy at the front edge.
Many are. Look for a teal pumpkin: it is the sign of a trunk handing out non-food treats such as glow sticks, stickers and small toys, part of the Teal Pumpkin Project for children with food allergies.
