More than 40 million children will go trick-or-treating this year, and doctors with the American College of Emergency Physicians want to make sure parents know what they're up against.
Experts at the CDC say children are four times more likely to be hit by a car on Halloween night, compared to any other night of the year. They also experience more eye injuries from costume accessories, and burns from flammable costumes.
Emergency room doctors suggest all children stay in groups with an adult chaperon on Halloween night, and that they have a flashlight and stay on the sidewalk.
Doctors are also encouraging local community center, malls and schools to organize Halloween festivities so kids don't have to walk outside to trick-or-treat.
