This Halloween evening will largely belong to keiki, who carry on the Oct. 31 tradition of trick-or-treating with frightful or delightful costumes to inspire an exchange of candy.

The Honolulu Police Department urges families to ensure that keiki under 12 trick-or-treat with adult supervision, and walk with a buddy if older. Pedestrian safety is also important, and both walkers and drivers must stay alert and follow rules of the road. Limit walking after dark, and use a flashlight if needed. Stay fire-safe, too: Keep decorations away from flames and heat sources, and don’t leave candles unattended inside those pumpkins.
