TOLEDO, Ohio (AP) - Proposed regulations for food trucks in a northwestern Ohio city have gone back to the mayor for more discussion after opposition from supporters of the mobile businesses.The Blade newspaper in Toledo reports that Toledo City Council declined to vote on Mayor Michael Collins' proposals last week. The regulations would have required operators of food trucks to apply for permits that could cost up to $1,000 per year and to obtain $1 million in liability insurance. The businesses also would be required to operate only during certain hours and in certain locations. Owners of food trucks blasted the proposals at last week's hearing. Collins later told the council the proposal was the beginning of a working document. He said he was taking it back and would await further discussion.
