Trick or treating is primarily for children, allowing them to roam their neighborhood in spooky costumes in hopes of receiving candy or playing tricks. The age limit for trick or treating is a hot topic among parents every Halloween. In the UK, there is no legal age limit for trick or treating, but parents of children under 16 engaging in antisocial behavior while trick or treating may be held responsible for any fines. As children grow older and more independent, parents may feel comfortable letting them trick or treat without adult supervision. However, according to experts, children under 12 should always be accompanied by an adult on Halloween for safety reasons.
