Go back and check the sign. If it says "When children are present" then I think you win this. Around here we have all different kinds of school signs. Some have blinking lights and some dont. Some just have the times printed on them that the school zone is in effect. Then there are some that just say "When kids are present". I dont trust them though and follow the school zone whether kids are present or not. Too easy for a cop to say he saw a child walking around.
