ODOT is asking drivers and trick-or-treaters to be especially cautious Thursday night. They want parents to make sure kids' costumes are visible, with reflective tape or lights, and to talk to kids about safely crossing streets and only at intersections,  and to watch for cars backing out of driveways. Drivers should be vigilant for pedestrians who aren't paying attention to cars. And if you're going to a Halloween party, make sure to have a sober ride home.
