UNDATED (KDAL) - Some safety reminders for Halloween. Little "Trick or Treaters" should wear costumes that don't restrict vision and are short enough to prevent tripping over them. Kids should use glow sticks or flashlights and put reflective tape on their outfits to be better visible after dark. Motorists are urged to use extra caution when driving in neighborhoods where little ones will be crossing streets or walking on them. For those passing out the treats, keep sidewalks and porches clear of obstructions and well lit. Both UMD and UWS are opening residence halls for Trick or Treating on Halloween from 5 to 7p-m. The children must be accompanied by a parent or guardian and free parking is offered. For the older crowd planning to make the Halloween Party Scene, law enforcement will be out looking for drunk drivers and urge party goers to plan for a sober ride home with a designated driver or a cab.
