Young children should never go trick or treating without an adult.

Older children should never trick or treat alone, they should always have at least two buddies.
Plan your trick or treat route before you go.
Carry at least one flashlight and check the batteries.
Take a cellular phone and watch with you if possible.
Wear flame retardant costumes.
Wait until you get home and your parents check your candy before you eat it.
Never go inside a house, only accept treats in the doorway.
Be weary of strangers trying to talk to you.
Walk, do not run.
Make sure to stay on sidewalks.
Cross the street at the corner or in a crosswalk.
Only visit homes that have their lights on.
