The local authority shall erect the signs within the first three hundred feet of the boundary of the local authority or within three hundred feet of the fixed system location, as applicable. If the signs cannot be located within the first three hundred feet of the boundary of the local authority or within three hundred feet of the fixed system location, the local authority shall erect the signs as close to that distance as possible. If a particular highway enters and exits the territory of a local authority multiple times, the local authority shall erect the signs as required by division (A)(1) of this section at the locations in each direction of travel where inbound traffic on the highway first enters the territory of the local authority and is not required to erect additional signs along such highway each time the highway reenters the territory of the local authority. The local authority is responsible for all costs associated with the erection, maintenance, and replacement, if necessary, of the signs. The local authority shall ensure that all signs erected under this division conform in size, color, location, and content to standards contained in the manual adopted by the department of transportation pursuant to section 4511.09 of the Revised Code and shall remain in place for as long as the local authority utilizes traffic law photo-monitoring devices to enforce any traffic law.
However, if a local authority is in substantial compliance with the requirements of division (A)(1) or (2) of this section, as applicable, a ticket issued by the local authority under sections 4511.096 to 4511.0912 of the Revised Code is valid.
