The safest time to go trick or treating with young children is when it is still light outside. The exact times vary depending on the location. It is common for young children to start trick or treating as early as 5:30 p.m.
Other ways to keep young children safe while trick-or-treating are to go out in groups with adult supervision, walk on sidewalks whenever possible, wear reflective clothing and carry a flashlight for when it gets dark. Young trick-or-treaters should wear costumes that fit right so they don't trip, wear shoes that are good for walking and make sure no masks or wigs hinder their ability to see well.
